Hispaniola

Hispaniola (,  also )   is an island in the Caribbean that is part of the Greater Antilles. Hispaniola is the most populous island in the West Indies, and the region's second largest in area, after the island of Cuba. The 76192 km2 island is divided into two separate nations: the Spanish-speaking Dominican Republic (48,445 km2 to the east and the French/Haitian Creole-speaking Haiti (27,750 km2 to the west. The only other divided island in the Caribbean is Saint Martin, which is shared between France (Saint Martin) and the Netherlands (Sint Maarten).

Hispaniola is the site of one of the first European forts in the Americas, La Navidad (1492–1493), as well as the first settlement and proper town, La Isabela (1493–1500), and the first permanent settlement, the current capital of the Dominican Republic, Santo Domingo (est. 1498). These settlements were founded successively during each of Christopher Columbus's first three voyages.

The Spanish Empire controlled the entire island of Hispaniola from the 1490s until the 17th century, when French pirates began establishing bases on the western side of the island. The official name was La Española, meaning "The Spanish (Island)". It was also called Santo Domingo, after Saint Dominic.

Etymology
The island was called various names by its native people, the Taíno. The Taino had no written language, hence, historical evidence for these names comes through three European historians: the Italian Peter Martyr d'Anghiera, and the Spaniards Bartolomé de las Casas and Gonzalo Fernández de Oviedo. Based on a comprehensive survey and map prepared by Andrés de Morales in 1508, Martyr reported that the island as a whole was called Quizquella (or Quisqueya) and Ayiti referred to a rugged mountainous region on the western end of the island. Diego Álvarez Chanca, a physician on Columbus's second voyage, also noted that “Ayiti” or Haïti was the westernmost province of the island. On the other hand, Oviedo and Las Casas both recorded that the entire island was called Ayiti by the Taíno. The French pronunciation of Haïti and Ayiti are identical; in English the "h" becomes aspirated.

When Columbus took possession of the island in 1492, he named it Insula Hispana in Latin and La Isla Española in Spanish, both meaning "the Spanish island". Las Casas shortened the name to Española, and when Peter Martyr detailed his account of the island in Latin, he rendered its name as Hispaniola.

Due to Taíno, Spanish and French influences on the island, historically the whole island was often referred to as Haïti, Hayti, Santo Domingo, or Saint-Domingue. Martyr's literary work was translated into English and French soon after being written, the name Hispaniola became the most frequently used term in English-speaking countries for the island in scientific and cartographic works. In 1918, the United States occupation government, led by Harry Shepard Knapp, obliged the use of the name Hispaniola on the island, and recommended the use of that name to the National Geographic Society.

The name "Haïti" was adopted by Haitian revolutionary Jean-Jacques Dessalines in 1804, as the official name of independent Saint-Domingue, in tribute to the Amerindian predecessors. It was also adopted as the official name of independent Santo Domingo, as the Republic of Spanish Haiti, a state that existed from November 1821 until its annexation by Haiti in February 1822.

Pre-Columbian
The Archaic Age people arrived from mainland Central America or northern South America about 6,000 years ago, and are thought to have practised a largely hunter-gatherer lifestyle. During the 1st millennium BC, the Arawakan-speaking ancestors of the Taino people began to migrate into the Caribbean. Unlike the Archaic peoples, they practiced the intensive production of pottery and agriculture. The earliest evidence of the ancestors of the Taino people on Hispaniola is the Ostionoid culture, which dates to around 600 AD. The Taino represented the dominant group on the island during the period of European contact. Each society on the island was a small independent kingdom with a lead known as a cacique. In 1492, which is considered the peak of the Taíno, there were five different kingdoms on the island, the Xaragua, Higuey (Caizcimu), Magua (Huhabo), Ciguayos (Cayabo or Maguana), and Marien (Bainoa). Many distinct Taíno languages also existed in this time period. There is still heated debate over the population of Taíno people on the island of Hispaniola in 1492, but estimates range from no more than a few tens of thousands, according to a 2020 genetic analysis, to upwards of 750,000.

A Taíno home consisted of a circular building with woven straw and palm leaves as covering. Most individuals slept in fashioned hammocks, but grass beds were also used. The cacique lived in a different structure with larger rectangular walls and a porch. The Taíno village also had a flat court used for ball games and festivals. Religiously, the Taíno people were polytheists, and their gods were called Zemí. Religious worship and dancing were common, and medicine men or priests also consulted the Zemí for advice in public ceremonies.

For food, the Taíno relied on meat and fish as a primary source for protein. On the island they hunted small mammals, but also snakes, worms, and birds. In lakes and in the sea they were able to catch ducks and turtles. The Taíno also relied on agriculture as a primary food source. The indigenous people of Hispaniola raised crops in a conuco, which is a large mound packed with leaves and fixed crops to prevent erosion. Some common agricultural goods were cassava, maize, squash, beans, peppers, peanuts, cotton, and tobacco, which was used as an aspect of social life and religious ceremonies.

The Taíno people traveled often and used hollowed canoes with paddles when on the water for fishing or for migration purposes, and upwards of 100 people could fit into a single canoe. The Taíno came frequently in contact with the Caribs, another indigenous tribe. The Taíno people had to defend themselves using bows and arrows with poisoned tips and some war clubs. When Columbus landed on Hispaniola, many Taíno leaders wanted protection from the Caribs.

Post-Columbian

Christopher Columbus first landed at Hispaniola on December 6, 1492, at a small bay he named San Nicolas, now called Môle-Saint-Nicolas on the north coast of present-day Haiti. He was welcomed in a friendly fashion by the indigenous people known as the Taíno. Trading with the natives yielded more gold than they had come across previously on the other Caribbean islands and Columbus was led to believe that much more gold would be found inland. Before he could explore further, his flagship, the Santa Maria, ran aground and sank in the bay on December 24. With only two smaller ships remaining for the voyage home, Columbus built a fortified encampment, La Navidad, on the shore and left behind 21 crewman to await his return the following year.

Colonization began in earnest the following year when Columbus brought 1,300 men to Hispaniola in November 1493 with the intention of establishing a permanent settlement. They found the encampment at Navidad had been destroyed and all the crewmen left behind killed by the natives. Columbus decided to sail east in search of a better site to found a new settlement. In January 1494 they established La Isabela in present-day Dominican Republic.

In 1496, the town of Nueva Isabela was founded. After being destroyed by a hurricane, it was rebuilt on the opposite side of the Ozama River and called Santo Domingo. It is the oldest permanent European settlement in the Americas. The island had an important role in the establishment of Latin American colonies for decades to come. Due to its strategic location, it was the military stronghold of conquistadors of the Spanish Empire, serving as a headquarters for the further colonial expansion into the Americas. The colony was a meeting point of European explorers, soldiers, and settlers who brought with them the culture, architecture, laws, and traditions of the Old World.

Spaniards imposed a harsh regime of forced labor and enslavement of the Taínos, as well as redirection of their food production and labor to Spaniards. This had a devastating impact on both mortality and fertility of the Taíno population over the first quarter century. Colonial administrators and Dominican and Hieronymite friars observed that the search for gold and agrarian enslavement through the encomienda system were deciminating the indigenous population. Demographic data from two provinces in 1514 shows a low birth rate, consistent with a 3.5% annual population decline. In 1503, Spaniards began to bring enslaved Africans after a charter was passed in 1501, allowing the import of African slaves by Ferdinand and Isabel. The Spanish believed Africans would be more capable of performing physical labor. From 1519 to 1533, the indigenous uprising known as Enriquillo's Revolt, after the Taíno cacique who led them, ensued, resulting from escaped African slaves on the island (maroons) possibly working with the Taíno people.

Precious metals played a large role in the history of the island after Columbus's arrival. One of the first inhabitants Columbus came across on this island was "a girl wearing only a gold nose plug". Soon the Taínos were trading pieces of gold for hawk's bells with their cacique declaring the gold came from Cibao. Traveling further east from Navidad, Columbus came across the Yaque del Norte River, which he named Río de Oro (River of Gold) because its "sands abound in gold dust".

On Columbus's return during his second voyage, he learned it was the chief Caonabo who had massacred his settlement at Navidad. While Columbus established a new settlement the village of La Isabela on Jan. 1494, he sent Alonso de Ojeda and 15 men to search for the mines of Cibao. After a six-day journey, Ojeda came across an area containing gold, in which the gold was extracted from streams by the Taíno people. Columbus himself visited the mines of Cibao on 12 March 1494. He constructed the Fort of Santo Tomás, present day Jánico, leaving Captain Pedro Margarit in command of 56 men. On 24 March 1495, Columbus with his ally Guacanagarix, embarked on a war of revenge against Caonabo, capturing him and his family while "killing many Indians and capturing others." Afterwards, "every person of fourteen years of age or upward was to pay a large hawk's bell of gold dust", every three months, as "the Spaniards were sure there was more gold in the island than the natives had yet found, and were determined to make them dig it out."

16th century: gold, sugar and pirates
Gold mining using forced indigenous labor began early on Hispaniola. Miguel Díaz and Francisco de Garay discovered large gold nuggets on the lower Haina River in 1496. These San Cristobal mines were later known as the Minas Viejas mines. Then, in 1499, the first major discovery of gold was made in the cordillera central, which led to a mining boom. By 1501 Columbus's cousin, Giovanni Colombo, had discovered gold near Buenaventura. The deposits were later known as Minas Nuevas. Two major mining areas resulted, one along San Cristobal-Buenaventura, and another in Cibao within the La Vega-Cotuy-Bonao triangle, while Santiago de los Caballeros, Concepción, and Bonao became mining towns. The gold rush of 1500–1508 ensued, and Ovando expropriated the gold mines of Miguel Díaz and Francisco de Garay in 1504, as pit mines became royal mines for Ferdinand II of Aragon, who reserved the best mines for himself, though placers were open to private prospectors. King Ferdinand kept 967 natives in the San Cristóbal mining area, supervised by salaried miners.

Under the royal governor Nicolás de Ovando, the indigenous people were forced to work in the gold mines. By 1503, the Spanish Crown legalized the allocation of private grants of indigenous labor to particular Spaniards for mining through the encomienda system. Once the indigenous were forced into mining far from their home villages, they suffered hunger and other difficult conditions. By 1508, the Taíno population of about 400,000 was reduced to 60,000, and by 1514, only 26,334 remained. About half resided in the mining towns of Concepción, Santiago, Santo Domingo, and Buenaventura. The repartimiento of 1514 accelerated emigration of the Spanish colonists, coupled with the exhaustion of the mines. The first documented outbreak of smallpox, previously an Eastern hemisphere disease, occurred on Hispaniola in December 1518 among enslaved African miners. Some scholars speculate that European diseases arrived before this date, but there is no compelling evidence for an outbreak. The natives had no acquired immunity to European diseases, including smallpox. By May 1519, as many as one-third of the remaining Taínos had died. In the century following the Spanish arrival on Hispaniola, the Taíno population fell by up to 95% of the population, out of a pre-contact population estimated from tens of thousands  to 8,000,000. Many authors have described the treatment of Tainos in Hispaniola under the Spanish Empire as genocide.

Sugar cane was introduced to Hispaniola by settlers from the Canary Islands, and the first sugar mill in the New World was established in 1516, on Hispaniola. The need for a labor force to meet the growing demands of sugar cane cultivation led to an exponential increase in the importation of slaves over the following two decades. The sugar mill owners soon formed a new colonial elite.

The first major slave revolt in the Americas occurred in Santo Domingo during 1521, when enslaved Muslims of the Wolof nation led an uprising in the sugar plantation of admiral Don Diego Colon, son of Christopher Columbus. Many of these insurgents managed to escape where they formed independent maroon communities in the south of the island.

Beginning in the 1520s, the Caribbean Sea was raided by increasingly numerous French pirates. In 1541, Spain authorized the construction of Santo Domingo's fortified wall, and in 1560 decided to restrict sea travel to enormous, well-armed convoys. In another move, which would destroy Hispaniola's sugar industry, in 1561 Havana, more strategically located in relation to the Gulf Stream, was selected as the designated stopping point for the merchant flotas, which had a royal monopoly on commerce with the Americas. In 1564, the island's main inland cities Santiago de los Caballeros and Concepción de la Vega were destroyed by an earthquake. In the 1560s, English privateers joined the French in regularly raiding Spanish shipping in the Americas.

17th century
By the early 17th century, Hispaniola and its nearby islands (notably Tortuga) became regular stopping points for Caribbean pirates. In 1606, the government of Philip III ordered all inhabitants of Hispaniola to move close to Santo Domingo, to fight against piracy. Rather than secure the island, his action meant that French, English, and Dutch pirates established their own bases on the less populated north and west coasts of the island. In 1625, French and English pirates arrived on the island of Tortuga, just off the northwest coast of Hispaniola, which was originally settled by a few Spanish colonists. The pirates were attacked in 1629 by Spanish forces commanded by Don Fadrique de Toledo, who fortified the island, and expelled the French and English. As most of the Spanish army left for the main island of Hispaniola to root out French colonists there, the French returned to Tortuga in 1630 and had constant battles for several decades. In 1654, the Spanish re-captured Tortuga for the last time. In 1655 the island of Tortuga was reoccupied by the English and French. In 1660 the English appointed a Frenchman as Governor who proclaimed the King of France, set up French colours, and defeated several English attempts to reclaim the island. In 1665, French colonization of the island was officially recognized by King Louis XIV. The French colony was given the name Saint-Domingue. By 1670 a Welsh privateer named Henry Morgan invited the pirates on the island of Tortuga to set sail under him. They were hired by the French as a striking force that allowed France to have a much stronger hold on the Caribbean region. Consequently, the pirates never really controlled the island and kept Tortuga as a neutral hideout. The capital of the French Colony of Saint-Domingue was moved from Tortuga to Port-de-Paix on the mainland of Hispaniola in 1676.

In 1680, new Acts of Parliament forbade sailing under foreign flags (in opposition to former practice). This was a major legal blow to the Caribbean pirates. Settlements were made in the Treaty of Ratisbon of 1684, signed by the European powers, that put an end to piracy. Most of the pirates after this time were hired out into the Royal services to suppress their former buccaneer allies. In the 1697 Treaty of Ryswick, Spain formally ceded the western third of the island to France. Saint-Domingue quickly came to overshadow the east in both wealth and population. Nicknamed the "Pearl of the Antilles", it became the most prosperous colony in the West Indies, with a system of human slavery used to grow and harvest sugar cane during a time when European demand for sugar was high. Slavery kept costs low and profit was maximized. It was an important port in the Americas for goods and products flowing to and from France and Europe.

18th century onwards
European colonists often died young due to tropical fevers, as well as from violent slave resistance in the late eighteenth century. In 1791, during the French Revolution, a major slave revolt broke out on Saint-Domingue. When the French Republic abolished slavery in the colonies on February 4, 1794, it was a European first. The ex-slave army joined forces with France in its war against its European neighbors. In the second 1795 Treaty of Basel (July 22), Spain ceded the eastern two-thirds of the island of Hispaniola, later to become the Dominican Republic. French settlers had begun to colonize some areas in the Spanish side of the territory.

Under Napoleon, France reimposed slavery in most of its Caribbean islands in 1802 and sent an army to bring the island into full control. However, thousands of the French troops succumbed to yellow fever during the summer months, and more than half of the French army died because of disease. After an extremely brutal war with atrocities committed on both sides, the French removed the surviving 7,000 troops in late 1803, the leaders of the revolution declared western Hispaniola the new nation of independent Haiti in early 1804. France continued to rule Spanish Santo Domingo. In 1805, Haitian troops of General Henri Christophe tried to conquer all of Hispaniola. They invaded Santo Domingo and sacked the towns of Santiago de los Caballeros and Moca, killing most of their residents, but news of a French fleet sailing towards Haiti forced General Christophe to withdraw from the east, leaving it in French hands. In 1808, following Napoleon's invasion of Spain, the criollos of Santo Domingo revolted against French rule and, with the aid of the United Kingdom, returned Santo Domingo to Spanish control. Fearing the influence of a society of slaves that had successfully revolted against their owners, the United States and European powers refused to recognize Haiti, the second republic in the Western Hemisphere. France demanded a high payment for compensation to slaveholders who lost their property, and Haiti was saddled with unmanageable debt for decades. Haiti would Annex Spanish Haiti which had recently gained independence. However, suppression of the Dominican culture would lead to the Dominican War of Independence. This is one of the reasons for the tensions between the two countries today. Haiti would become one of the poorest countries in the Americas, while the Dominican Republic gradually has developed into one of the largest economies of Central America and the Caribbean.

Geography

Hispaniola is the second-largest island in the Caribbean (after Cuba), with an area of 76192 km2, 48440 km2 of which is under the sovereignty of the Dominican Republic occupying the eastern portion and 27750 km2 under the sovereignty of Haiti occupying the western portion.

The island of Cuba lies 80 km to the west across the Windward Passage; to the southwest lie Jamaica, separated by the Jamaica Channel, the Cayman Islands and Navassa Island; 190 km. Puerto Rico lies 130 km east of Hispaniola across the Mona Passage. The Bahamas and Turks and Caicos Islands lie to the north. Its westernmost point is known as Cap Carcasse. Cuba, Cayman Islands, Navassa Island, Hispaniola, Jamaica, and Puerto Rico are collectively known as the Greater Antilles. Hispaniola is also a part of the Antilles and the West Indies.

The island has five major ranges of mountains: The Central Range, known in the Dominican Republic as the Cordillera Central, spans the central part of the island, extending from the south coast of the Dominican Republic into northwestern Haiti, where it is known as the Massif du Nord. This mountain range boasts the highest peak in the Antilles, Pico Duarte at 3101 m above sea level. The Cordillera Septentrional runs parallel to the Central Range across the northern end of the Dominican Republic, extending into the Atlantic Ocean as the Samaná Peninsula. The Cordillera Central and Cordillera Septentrional are separated by the lowlands of the Cibao Valley and the Atlantic coastal plains, which extend westward into Haiti as the Plaine du Nord (Northern Plain). The lowest of the ranges is the Cordillera Oriental, in the eastern part of the country.

The Sierra de Neiba rises in the southwest of the Dominican Republic, and continues northwest into Haiti, parallel to the Cordillera Central, as the Montagnes Noires, Chaîne des Matheux and the Montagnes du Trou d'Eau. The Plateau Central lies between the Massif du Nord and the Montagnes Noires, and the Plaine de l'Artibonite lies between the Montagnes Noires and the Chaîne des Matheux, opening westward toward the Gulf of Gonâve, the largest gulf of the Antilles.

The southern range begins in the southwesternmost Dominican Republic as the Sierra de Bahoruco, and extends west into Haiti as the Massif de la Selle and the Massif de la Hotte, which form the mountainous spine of Haiti's southern peninsula. Pic de la Selle is the highest peak in the southern range, the third highest peak in the Antilles and consequently the highest point in Haiti, at 2680 m above sea level. A depression runs parallel to the southern range, between the southern range and the Chaîne des Matheux-Sierra de Neiba. It is known as the Plaine du Cul-de-Sac in Haiti, and Haiti's capital Port-au-Prince lies at its western end. The depression is home to a chain of salt lakes, including Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic.

The island has four distinct ecoregions. The Hispaniolan moist forests ecoregion covers approximately 50% of the island, especially the northern and eastern portions, predominantly in the lowlands but extending up to 2100 m elevation. The Hispaniolan dry forests ecoregion occupies approximately 20% of the island, lying in the rain shadow of the mountains in the southern and western portion of the island and in the Cibao valley in the center-north of the island. The Hispaniolan pine forests occupy the mountainous 15% of the island, above 850 m elevation. The flooded grasslands and savannas ecoregion in the south central region of the island surrounds a chain of lakes and lagoons in which the most notable include that of Lake Azuei and Trou Caïman in Haiti and the nearby Lake Enriquillo in the Dominican Republic, which is not only the lowest point of the island, but also the lowest point for an island country.

Climate

Hispaniola's climate shows considerable variation due to its diverse mountainous topography, and is the most varied island of all the Antilles. Except in the Northern Hemisphere summer season, the predominant winds over Hispaniola are the northeast trade winds. As in Jamaica and Cuba, these winds deposit their moisture on the northern mountains, and create a distinct rain shadow on the southern coast, where some areas receive as little as 400 mm of rainfall, and have semi-arid climates. Annual rainfall under 600 mm also occurs on the southern coast of Haiti's northwest peninsula and in the central Azúa region of the Plaine du Cul-de-Sac. In these regions, moreover, there is generally little rainfall outside hurricane season from August to October, and droughts are by no means uncommon when hurricanes do not come. On the northern coast, in contrast, rainfall may peak between December and February, though some rain falls in all months of the year. Annual amounts typically range from 1700 to 2000 mm on the northern coastal lowlands; there is probably much more in the Cordillera Septentrional, though no data exist. The interior of Hispaniola, along with the southeastern coast centered around Santo Domingo, typically receives around 1400 mm per year, with a distinct season from May to October. Usually, this wet season has two peaks: one around May, the other around the hurricane season. In the interior highlands, rainfall is much greater, around 3100 mm per year, but with a similar pattern to that observed in the central lowlands.

The variations of temperature depend on altitude and are much less marked than rainfall variations in the island. Lowland Hispaniola is generally more hot and humid, with temperatures averaging 28 C. with high humidity during the daytime, and around 20 C at night. At higher altitudes, temperatures fall steadily, so that frosts occur during the dry season on the highest peaks, where maxima are no higher than 18 C.

Fauna
There are many bird species in Hispaniola, and the island's amphibian species are also diverse. There are many species endemic to the island including insects and other invertebrates, reptiles, amphibians, fishs, birds and mammals (originally animals, native animals) and also (imported animals, introduced animals, not native animals or invasive species) just like farm animals, transport animals, house animals, pets and more. The two endemic terrestrial mammals on the island are the Hispaniolan hutia (Plagiodontia aedium) and the Hispaniolan solenodon (Solenodon paradoxus). There are also many avian species on the island, with six endemic genera (Calyptophilus, Dulus, Nesoctites, Phaenicophilus, Xenoligea and Microligea). More than half of the original distribution of its ecoregions has been lost due to habitat destruction impacting the local fauna and some of the original animals either threat, threatened with extinction or totally extinct, because of climate change or because they have been hunted by humans or their habitats have been felled or changed for some reasons or have become some of the animals have been threatened by (introduced animals, not native animals or invasive species) or there are fighting for space to survive and perhaps some animals that feed on the same plants or animals or just something like that.

Flora
The island has four distinct ecoregions. The Hispaniolan moist forests ecoregion covers approximately 50% of the island, especially the northern and eastern portions, predominantly in the lowlands but extending up to 2100 m elevation. The Hispaniolan dry forests ecoregion occupies approximately 20% of the island, lying in the rain shadow of the mountains in the southern and western portion of the island, and in the Cibao valley in the center-north of the island. The Hispaniolan pine forests occupy the mountainous 15% of the island, above 850 m elevation. The flooded grasslands and savannas ecoregion in the south central region of the island surrounds a chain of lakes and lagoons, the most notable of which are Etang Saumatre and Trou Caïman in Haiti and the nearby Lake Enriquillo in the Dominican Republic.

In Haiti, deforestation has long been cited by scientists as a source of ecological crisis; the timber industry dates back to French colonial rule. Haiti has seen a dramatic reduction of forests due to the excessive and increasing use of charcoal as fuel for cooking. Various media outlets have suggested that the country has just 2% forest cover, but this has not been substantiated by research.

Also extremely important are the rarely mentioned species of Pinguicula casabitoana (a carnivorous plant), Gonocalyx tetraptera, Gesneria sylvicola, Lyonia alaini and Myrcia saliana, as well as palo de viento (Didymopanax tremulus), jaiqui (Bumelia salicifolia), pino criciolio) (pino criciol), sangre de pollo (Mecranium amigdalinum) and palo santo (Alpinia speciosa). According to reports in the Dominican Republic and Haiti, the flora in this naturally protected area consists of 621 species of vascular plants, of which 153 are highly endemic to La Hispaniola. The most prominent endemic species of flora that abound in the area are Ebano Verde (green ebony), Magnolia pallescens, a highly endangered hardwood.

Recent in-depth studies of satellite imagery and environmental analysis regarding forest classification conclude that Haiti actually has approximately 30% tree cover; this is, nevertheless, a stark decrease from the country's 60% forest cover in 1925. The country has been significantly deforested over the last 50 years, resulting in the desertification of many portions of Haitian territory. Haiti's poor citizens use cooking fires often, and this is a major culprit behind the nation's loss of trees. Haitians use trees as fuel either by burning the wood directly, or by first turning it into charcoal in ovens. Seventy-one percent of all fuel consumed in Haiti is wood or charcoal. Haiti's government began establishing protected areas across the country in 1968. These 26 areas today represent nearly 7 per cent of the country's land and 1.5 per cent of its waters.

In the Dominican Republic, the forest cover has increased. In 2003, the Dominican Republic's forest cover had been reduced to 32% of its land area, but by 2011, forest cover had increased to nearly 40%. The success of the Dominican forest growth is due to several Dominican government policies and private organizations for the purpose of reforesting, and a strong educational campaign that has resulted in increased awareness by the Dominican people of the importance of forests for their welfare and other forms of life on the island.

Demographics

Hispaniola is the most populous Caribbean island with a combined population of 23 million inhabitants.

The Dominican Republic is a Hispanophone nation of approximately 11.3 million people. Spanish is spoken by essentially all Dominicans as a primary language. Roman Catholicism is the official and dominant religion and some Evangelicalism and Protestant churches and The Church of Jesus Christ and minority religions such as African religions, Afro-American religions-African diaspora religions, Haitian Vodou, Dominican Vodou, Dominican Santeria-Congos Del Espiritu Santo, Dominican Protestants-Pentecostals, Judaism, Islam and Baháʼí Faith, Hinduism, Buddhism, Unitarian Universalism, Jehovah's Witnesses, Pentecostalism and others also exist.

Haiti is a Creole-speaking nation of roughly 11.7 million people. Although French is spoken as a primary language by the educated and wealthy minority, virtually the entire population speaks Haitian Creole, one of several French-derived creole languages. Roman Catholicism is the dominant religion, practiced by more than half the population, although in some cases in combination with Haitian Vodou faith. Another 25% of the populace belong to Protestant churches.

Ethnic composition
The ethnic composition of the Dominican population is 73% mixed ethnicity, 16% white and 11% black. Descendants of early Spanish settlers and of black slaves from West Africa constitute the two main racial strains.

The ethnic composition of Haiti is estimated to be 95% black and 5% white and Mulatto.

In recent times, Dominican and Puerto Rican researchers identified in the current Dominican population the presence of genes belonging to the aborigines of the Canary Islands (commonly called Guanches). These genes also have been detected in Puerto Rico.

Economics

The island has the largest economy in the Greater Antilles; however, most of the economic development is found in the Dominican Republic, the Dominican economy being nearly 800% larger than the Haitian economy. , the estimated annual per capita income is US$868 in Haiti and US$8,050 in the Dominican Republic.

The divergence between the level of economic development in Haiti and the Dominican Republic makes its border the highest contrast of all western land borders.

Natural resources
The island also has an economic history and current day interest and involvement in precious metals. In 1860, it was observed that the island contained a large supply of gold, which the early Spaniards had hardly developed. By 1919, Condit and Ross noted that much of the island was covered by government granted concessions for mining different types of minerals. Besides gold, these minerals included silver, manganese, copper, magnetite, iron and nickel.

Mining operations in 2016 have taken advantage of the volcanogenic massive sulfide ore deposits around Maimón. To the northeast, the Pueblo Viejo Gold Mine was operated by state-owned Rosario Dominicana from 1975 until 1991. In 2009, Pueblo Viejo Dominicana Corporation, formed by Barrick Gold and Goldcorp, started open-pit mining operations of the Monte Negro and Moore oxide deposits. The mined ore is processed with gold cyanidation. Pyrite and sphalerite are the main sulfide minerals found in the 120-meter thick volcanic conglomerates and agglomerates, which constitute the world's second largest sulphidation gold deposit.

Between Bonao and Maimón, Falconbridge Dominicana has been mining nickel laterites since 1971. The Cerro de Maimon copper/gold open-pit mine southeast of Maimón has been operated by Perilya since 2006. Copper is extracted from the sulfide ores, while gold and silver are extracted from both the sulfide and the oxide ores. Processing is via froth flotation and cyanidation. The ore is located in the VMS Early Cretaceous Maimón Formation. Goethite enriched with gold and silver is found in the 30-meter thick oxide cap. Below that cap is a supergene zone containing pyrite, chalcopyrite, and sphalerite. Below the supergene zone is found the unaltered massive sulphide mineralization.

Halle Berry

Halle Maria Berry (born Maria Halle Berry; August 14, 1966) is an American actress. She began her career as a model and entered several beauty contests, finishing as the first runner-up in the Miss USA pageant and coming in sixth in the Miss World 1986. Her breakthrough film role was in the romantic comedy Boomerang (1992), alongside Eddie Murphy, which led to roles in The Flintstones (1994) and Bulworth (1998) as well as the television film Introducing Dorothy Dandridge (1999), for which she won a Primetime Emmy Award and a Golden Globe Award.

Berry established herself as one of the highest-paid actresses in Hollywood during the 2000s. For her performance of a struggling widow in the romantic drama Monster's Ball (2001), Berry became the only African-American woman to win the Academy Award for Best Actress, and the first woman of color. Berry took on high-profile roles such as Storm in four installments of the X-Men film series (2000–2014), the henchwoman of a robber in the thriller Swordfish (2001), Bond girl Jinx in Die Another Day (2002), and the title role in the much-derided Catwoman (2004).

A varying critical and commercial reception followed in subsequent years, with Perfect Stranger (2007), Cloud Atlas (2012) and The Call (2013) being among her notable film releases in that period. Berry launched a production company, 606 Films, in 2014 and has been involved in the production of a number of projects in which she performed, such as the CBS science fiction series Extant (2014–2015). She appeared in the action films Kingsman: The Golden Circle (2017) and John Wick: Chapter 3 – Parabellum (2019) and made her directorial debut with the Netflix drama Bruised (2020).

Berry has been a Revlon spokesmodel since 1996. She was formerly married to baseball player David Justice, singer-songwriter Eric Benét, and actor Olivier Martinez. She has two children, one with Martinez and another with model Gabriel Aubry.

Early life
Berry was born Maria Halle Berry in Cleveland, Ohio, on August 14, 1966, to Judith Ann (née Hawkins), an English immigrant from Liverpool, and Jerome Jesse Berry, an African-American man. Her name was legally changed to Halle Maria Berry at the age of five. Her parents selected her middle name from Halle's Department Store, which was then a local landmark in Cleveland. Berry's mother worked as a psychiatric nurse, and her father worked in the same hospital as an attendant in the psychiatric ward; he later became a bus driver. They divorced when Berry was four years old, and she and her older sister Heidi Berry-Henderson were raised exclusively by their mother. She has been estranged from her father since childhood, noting in 1992 that she did not even know if he was still alive. Her father was abusive to her mother, and Berry has recalled witnessing her mother being beaten daily, kicked down stairs, and hit in the head with a wine bottle.

Berry grew up in Oakwood, Ohio, and graduated from Bedford High School, where she was a cheerleader, honor student, editor of the school newspaper, and prom queen. She worked in the children's department at Higbee's Department store. She then studied at Cuyahoga Community College. In the 1980s, she entered several beauty contests, winning Miss Teen All American 1985 and Miss Ohio USA in 1986. She was the 1986 Miss USA first runner-up to Christy Fichtner of Texas. In the Miss USA 1986 pageant interview competition, she said she hoped to become an entertainer or to have something to do with the media. Her interview was awarded the highest score by the judges. She was the first African-American Miss World entrant in 1986, where she finished sixth and Trinidad and Tobago's Giselle Laronde was crowned Miss World.

Early work and breakthrough (1989–1999)
In 1989, Berry moved to New York City to pursue her acting ambitions. During her early time there, she ran out of money and briefly lived in a homeless shelter and a YMCA. Her situation improved by the end of that year, and she was cast in the role of model Emily Franklin in the short-lived ABC television series Living Dolls, which was shot in New York and was a spin-off of the hit series Who's the Boss?. During the taping of Living Dolls, she lapsed into a coma and was diagnosed with type 1 diabetes. After the cancellation of Living Dolls, she moved to Los Angeles.

Berry's film debut was in a small role for Spike Lee's Jungle Fever (1991), in which she played Vivian, a drug addict. That same year, Berry had her first co-starring role in Strictly Business. In 1992, Berry portrayed a career woman who falls for the lead character played by Eddie Murphy in the romantic comedy Boomerang. The following year, she caught the public's attention as a headstrong biracial slave in the TV adaptation of Queen: The Story of an American Family, based on the book by Alex Haley. Berry was also in the live-action Flintstones film as Sharon Stone, a sultry secretary who attempts to seduce Fred Flintstone.

Berry tackled a more serious role, playing a former drug addict struggling to regain custody of her son in Losing Isaiah (1995), starring opposite Jessica Lange. She portrayed Sandra Beecher in Race the Sun (1996), which was based on a true story, shot in Australia, and co-starred alongside Kurt Russell in Executive Decision. Beginning in 1996, she was a Revlon spokeswoman for seven years and renewed her contract in 2004.

She starred alongside Natalie Deselle Reid in the 1997 comedy film B*A*P*S. In 1998, Berry received praise for her role in Bulworth as an intelligent woman raised by activists who gives a politician (Warren Beatty) a new lease on life. The same year, she played the singer Zola Taylor, one of the three wives of pop singer Frankie Lymon, in the biopic Why Do Fools Fall in Love.

In the 1999 HBO biopic Introducing Dorothy Dandridge, she portrayed Dorthy Dandridge, the first African American woman to be nominated for the Academy Award for Best Actress. It was to Berry a heartfelt project that she introduced, co-produced and fought intensely for it to come through. Berry won awards including a Primetime Emmy Award and Golden Globe Award.

Worldwide recognition (2000–2004)
Berry portrayed the mutant superhero Storm in the film adaptation of the comic book series X-Men (2000) and its sequels, X2 (2003), X-Men: The Last Stand (2006) and X-Men: Days of Future Past (2014). In 2001, Berry appeared in the film Swordfish, which featured her first topless scene. At first, she was opposed to a sunbathing scene in the film in which she would appear topless, but Berry eventually agreed. Some people attributed her change of heart to a substantial increase in the amount Warner Bros. offered her; she was reportedly paid an additional $500,000 for the short scene. Berry denied these stories, telling one interviewer that they amused her and "made for great publicity for the movie." After turning down numerous roles that required nudity, she said she decided to make Swordfish because her then-husband, Eric Benét, supported her and encouraged her to take risks.

Berry appeared as Leticia Musgrove, the troubled wife of an executed murderer (Sean Combs), in the 2001 feature film Monster's Ball. Her performance was awarded the National Board of Review and the Screen Actors Guild Award for Best Actress. She became the only African-American woman to win the Academy Award for Best Actress. The NAACP issued the statement: "Congratulations to Halle Berry and Denzel Washington for giving us hope and making us proud. If this is a sign that Hollywood is finally ready to give opportunity and judge performance based on skill and not on skin color then it is a good thing." This role generated controversy. Her graphic nude love scene with a racist character played by co-star Billy Bob Thornton was the subject of much media chatter and discussion among African Americans. Many in the African-American community were critical of Berry for taking the part. Berry responded: "I don't really see a reason to ever go that far again. That was a unique movie. That scene was special and pivotal and needed to be there, and it would be a really special script that would require something like that again."

Berry asked for a higher fee for Revlon advertisements after winning the Oscar. Ron Perelman, the cosmetics firm's chief, congratulated her, saying how happy he was that she modeled for his company. She replied, "Of course, you'll have to pay me more." Perelman stalked off in a rage. In accepting her award, she gave an acceptance speech honoring previous black actresses who had never had the opportunity. She said, "This moment is so much bigger than me. This is for every nameless, faceless woman of color who now has a chance tonight because this door has been opened."

As Bond girl Giacinta 'Jinx' Johnson in the 2002 blockbuster Die Another Day, Berry recreated a scene from Dr. No, emerging from the surf to be greeted by James Bond as Ursula Andress had 40 years earlier. Lindy Hemming, costume designer on Die Another Day, had insisted that Berry wear a bikini and knife as a homage. Berry has said of the scene: "It's splashy", "exciting", "sexy", "provocative" and "it will keep me still out there after winning an Oscar." According to an ITV news poll, Jinx was voted the fourth toughest girl on screen of all time. Berry was hurt during filming when debris from a smoke grenade flew into her eye. It was removed in a 30-minute operation. After Berry won the Academy Award, rewrites were commissioned to give her more screentime for X2.

She starred in the psychological thriller Gothika opposite Robert Downey, Jr. in November 2003, during which she broke her arm in a scene with Downey, who twisted her arm too hard. Production was halted for eight weeks. It was a moderate hit at the United States box office, taking in $60 million; it earned another $80 million abroad. Berry appeared in the nu metal band Limp Bizkit's music video for "Behind Blue Eyes" for the motion picture soundtrack for the film. The same year, she was named No. 1 in FHM's 100 Sexiest Women in the World poll.

Berry starred as the title role in the film Catwoman, for which she received US$12.5 million. and is widely regarded by critics as one of the worst films ever made. She was awarded the Worst Actress Razzie Award for her performance; she appeared at the ceremony to accept the award in person (while holding her Oscar from Monster's Ball) with a sense of humor, considering it an experience of the "rock bottom" in order to be "at the top." Holding the Academy Award in one hand and the Razzie in the other she said, "I never in my life thought that I would be up here, winning a Razzie! It's not like I ever aspired to be here, but thank you. When I was a kid, my mother told me that if you could not be a good loser, then there's no way you could be a good winner."

Established actress and career fluctuations (2005–2013)

Her next film appearance was in the Oprah Winfrey-produced ABC television film Their Eyes Were Watching God (2005), an adaptation of Zora Neale Hurston's novel, with Berry portraying a free-spirited woman whose unconventional sexual mores upset her 1920s contemporaries in a small community. She received her second Primetime Emmy Award nomination for her role. Also in 2005, she served as an executive producer in Lackawanna Blues, and landed her voice for the character of Cappy, one of the many mechanical beings in the animated feature Robots.

In the thriller Perfect Stranger (2007), Berry starred with Bruce Willis, playing a reporter who goes undercover to uncover the killer of her childhood friend. The film grossed a modest US$73 million worldwide, and received lukewarm reviews from critics, who felt that despite the presence of Berry and Willis, it is "too convoluted to work, and features a twist ending that's irritating and superfluous." Her next 2007 film release was the drama Things We Lost in the Fire, co-starring Benicio del Toro, where she took on the role of a recent widow befriending the troubled friend of her late husband. The film was the first time in which she worked with a female director, Danish Susanne Bier, giving her a new feeling of "thinking the same way," which she appreciated. While the film made US$8.6 million in its global theatrical run, it garnered positive reviews from writers; The Austin Chronicle found the film to be "an impeccably constructed and perfectly paced drama of domestic and internal volatility" and felt that "Berry is brilliant here, as good as she's ever been."

In April 2007, Berry was awarded a star on the Hollywood Walk of Fame in front of the Kodak Theatre at 6801 Hollywood Boulevard for her contributions to the film industry, and by the end of the decade, she established herself as one of the highest-paid actresses in Hollywood, earning an estimated $10 million per film.

In the independent drama Frankie and Alice (2010), Berry played the leading role of a young multiracial American woman with dissociative identity disorder struggling against her alter personality to retain her true self. The film received a limited theatrical release, to a mixed critical response. The Hollywood Reporter nevertheless described the film as "a well-wrought psychological drama that delves into the dark side of one woman's psyche" and found Berry to be "spellbinding" in it. She earned the African-American Film Critics Association Award for Best Actress and a Golden Globe Award nomination for Best Actress – Motion Picture Drama. She next made part of a large ensemble cast in Garry Marshall's romantic comedy New Year's Eve (2011), with Michelle Pfeiffer, Jessica Biel, Robert De Niro, Josh Duhamel, Zac Efron, Sarah Jessica Parker, and Sofía Vergara, among many others. In the film, she took on the supporting role of a nurse befriending a man in the final stages (De Niro). While the film was panned by critics, it made US$142 million worldwide.

In 2012, Berry starred as an expert diver tutor alongside then-husband Olivier Martinez in the little-seen thriller Dark Tide, and led an ensemble cast opposite Tom Hanks and Jim Broadbent in The Wachowskis's epic science fiction film Cloud Atlas (2012), with each of the actors playing six different characters across a period of five centuries. Budgeted at US$128.8 million, Cloud Atlas made US$130.4 million worldwide, and garnered polarized reactions from both critics and audiences.

Berry appeared in a segment of the independent anthology comedy Movie 43 (2013), which the Chicago Sun-Times called "the Citizen Kane of awful." Berry found greater success with her next performance, as a 9-1-1 operator receiving a call from a girl kidnapped by a serial killer, in the crime thriller The Call (2013). Berry was drawn to "the idea of being a part of a movie that was so empowering for women. We don't often get to play roles like this, where ordinary people become heroic and do something extraordinary." Manohla Dargis of The New York Times found the film to be "an effectively creepy thriller," while reviewer Dwight Brown felt that "the script gives Berry a blue-collar character she can make accessible, vulnerable and gutsy[...]." The Call was a sleeper hit, grossing US$68.6 million around the globe.

Continued film and television work (2014–present)
In 2014, Berry signed on to star and serve as a co-executive producer in CBS drama series Extant, where she took on the role of Molly Woods, an astronaut who struggles to reconnect with her husband and android son after spending 13 months in space. The show ran for two seasons until 2015, receiving largely positive reviews from critics. USA Today remarked: "She [Halle Berry] brings a dignity and gravity to Molly, a projected intelligence that allows you to buy her as an astronaut and to see what has happened to her as frightening rather than ridiculous. Berry's all in, and you float along." Also in 2014, Berry launched a new production company, 606 Films, with producing partner Elaine Goldsmith-Thomas. It is named after the Anti-Paparazzi Bill, SB 606, that the actress pushed for and which was signed into law by California Governor Jerry Brown in the fall of 2013. The new company emerged as part of a deal for Berry to work in Extant.

In the stand-up comedy concert film Kevin Hart: What Now? (2016), Berry appeared as herself, opposite Kevin Hart, attending a poker game event that goes horribly wrong. She provided uncredited vocals to the song, "Calling All My Lovelies" by Bruno Mars from his third studio album, 24K Magic (2016). Kidnap, an abduction thriller Berry filmed in 2014, was released in 2017. In the film, she starred as a diner waitress tailing a vehicle when her son is kidnapped by its occupants. Kidnap grossed US$34 million and garnered mixed reviews from writers, who felt that it "strays into poorly scripted exploitation too often to take advantage of its pulpy premise — or the still-impressive talents of [Berry]." She next played an agent employed by a secret American spy organisation in the action comedy sequel Kingsman: The Golden Circle (2017), as part of an ensemble cast, consisting of Colin Firth, Taron Egerton, Mark Strong, Julianne Moore, and Elton John. While critical response towards the film was mixed, it made US$414 million worldwide.

Alongside Daniel Craig, Berry starred as a working-class mother during the 1992 Los Angeles riots in Deniz Gamze Ergüven's drama Kings (2017). The film found a limited theatrical release following its initial screening at the Toronto International Film Festival, and as part of an overall lukewarm reception, Variety noted: "It should be said that Berry has given some of the best and worst performances of the past quarter-century, but this is perhaps the only one that swings to both extremes in the same movie." Berry competed against James Corden in the first rap battle on the first episode of TBS's Drop the Mic, originally aired on October 24, 2017.

She played Sofia, an assassin, in the film John Wick: Chapter 3 – Parabellum, which was released on May 17, 2019, by Lionsgate. She is, as of February 2019, executive producer of the BET television series Boomerang, based on the film in which she starred. The series premiered February 12, 2019.

Berry made her directorial debut with the feature Bruised in which she plays a disgraced MMA fighter named Jackie Justice, who reconnects with her estranged son. The film premiered at the Toronto International Film Festival in September 2020 and was released on Netflix in November 2021. Berry received a positive review from Deadline for her performance.

In January 2023, Berry signed with Range Media Partners as a producer and director.

Berry was ranked No. 1 on People "50 Most Beautiful People in the World" list in 2003 after making the top ten seven times and appeared No. 1 on FHM "100 Sexiest Women in the World" the same year. She was named Esquire magazine's "Sexiest Woman Alive" in October 2008, about which she stated: "I don't know exactly what it means, but being 42 and having just had a baby, I think I'll take it." Men's Health ranked her at No. 35 on their "100 Hottest Women of All-Time" list. In 2009, she was voted #23 on Empire's 100 Sexiest Film Stars. The same year, rapper Hurricane Chris released a song titled "Halle Berry (She's Fine)" extolling Berry's beauty and sex appeal. At the age of 42 (in 2008), she was named the "Sexiest Black Woman" by Access Hollywood's "TV One Access" survey. Born to an African-American father and a white mother, Berry has stated that her biracial background was "painful and confusing" when she was a young woman, and she made the decision early on to identify as a black woman because she knew that was how she would be perceived.

Personal life
Berry dated Chicago dentist John Ronan from March 1989 to October 1991. In November 1993, Ronan sued Berry for $80,000 in what he claimed were unpaid loans to help launch her career. Berry contended that the money was a gift, and a judge dismissed the case because Ronan did not list Berry as a debtor when he filed for bankruptcy in 1992.

According to Berry, a beating from a former abusive boyfriend during the filming of The Last Boy Scout in 1991 punctured her eardrum and caused her to lose 80% of her hearing in her left ear. She has never named the abuser, but said that he was someone "well known in Hollywood". In 2004, her former boyfriend Christopher Williams accused Wesley Snipes of being responsible for the incident, saying, "I'm so tired of people thinking I'm the guy [who did it]. Wesley Snipes busted her eardrum, not me."

Berry first saw baseball player David Justice on TV playing in an MTV celebrity baseball game in February 1992. When a reporter from Justice's hometown of Cincinnati told her that Justice was a fan, Berry gave her phone number to the reporter to give to Justice. Berry married Justice shortly after midnight on January 1, 1993. Following their separation in February 1996, Berry stated publicly that she was so depressed that she had considered taking her own life. Berry and Justice were divorced on June 20, 1997.

In May 2000, Berry pleaded no contest to a charge of leaving the scene of a car accident; she was sentenced to three years' probation, fined $13,500, and ordered to perform 200 hours of community service.

Berry married her second husband, singer-songwriter Eric Benét, on January 24, 2001, following a two-year courtship. Benét underwent treatment for sex addiction in 2002. By early October 2003, they had separated, and their divorce was finalized on January 3, 2005.

In November 2005, Berry began dating French-Canadian model Gabriel Aubry, whom she had met at a Versace photoshoot. Berry gave birth to their daughter in March 2008. On April 30, 2010, Berry and Aubry announced that their relationship had ended some months earlier. In January 2011, Berry and Aubry became involved in a highly publicized custody battle,  centered primarily on Berry's desire to move with their daughter from Los Angeles, where Berry and Aubry resided, to France, the home of French actor Olivier Martinez, whom Berry had started dating in 2010, having met him while filming Dark Tide in South Africa. Aubry objected to the move on the ground that it would interfere with their joint custody arrangement. In November 2012, a judge denied Berry's request to move the couple's daughter to France. Less than two weeks later, on November 22, 2012, Aubry and Martinez were both treated at a hospital for injuries after engaging in a physical altercation at Berry's residence. Martinez performed a citizen's arrest on Aubry, and because it was considered a domestic violence incident, was granted a temporary emergency protective order preventing Aubry from coming within 100 yards of Berry, Martinez, and the child with whom he shares custody with Berry, until November 29, 2012. In turn, Aubry obtained a temporary restraining order against Martinez on November 26, 2012, asserting that the fight had begun when Martinez had threatened to kill Aubry if he did not allow the couple to move to France. Leaked court documents included photos showing significant injuries to Aubry's face, which were widely displayed in the media. On November 29, 2012, Berry's lawyer announced that Berry and Aubry had reached an amicable custody agreement in court. In June 2014, a Superior Court ruling called for Berry to pay Aubry $16,000 a month in child support as well as a retroactive payment of $115,000 and $300,000 for Aubry's attorney fees.

Berry and Martinez confirmed their engagement in March 2012, and married in France on July 13, 2013. In October 2013, Berry gave birth to their son. In 2015, after two years of marriage, the couple announced they were divorcing. The divorce was finalized in December 2016. In August 2023, issues dealing with custody and child support were settled.

Berry started dating American musician Van Hunt in 2020, which was revealed through her Instagram.

Activism
Along with Pierce Brosnan, Cindy Crawford, Jane Seymour, Dick Van Dyke, Téa Leoni, and Daryl Hannah, Berry successfully fought in 2006 against the Cabrillo Port Liquefied Natural Gas facility that was proposed off the coast of Malibu. Berry said, "I care about the air we breathe, I care about the marine life and the ecosystem of the ocean." In May 2007, Governor Arnold Schwarzenegger vetoed the facility. Hasty Pudding Theatricals gave her its 2006 Woman of The Year award. Berry took part in a nearly 2,000-house cellphone-bank campaign for Barack Obama in February 2008. In April 2013, she appeared in a video clip for Gucci's "Chime for Change" campaign that aims to raise funds and awareness of women's issues in terms of education, health, and justice. In August 2013, Berry testified alongside Jennifer Garner before the California State Assembly's Judiciary Committee in support of a bill that would protect celebrities' children from harassment by photographers. The bill passed in September.

In May 2024, Berry advocated for more research and education on menopause by supporting a bill introduced by Senators Patty Murray and Lisa Murkowski. Berry said, "I'm in menopause, OK?... The shame has to be taken out of menopause. We have to talk about this very normal part of our life that happens. Our doctors can't even say the word to us, let alone walk us through the journey."

Robert Koch

Heinrich Hermann Robert Koch (, ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist. As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology. As such he is popularly nicknamed the father of microbiology (with Louis Pasteur ), and as the father of medical bacteriology. His discovery of the anthrax bacterium (Bacillus anthracis) in 1876 is considered as the birth of modern bacteriology. Koch used his discoveries to establish that germs "could cause a specific disease" and directly provided proofs for the germ theory of diseases, therefore creating the scientific basis of public health, saving millions of lives. For his life's work Koch is seen as one of the founders of modern medicine.

While working as a private physician, Koch developed many innovative techniques in microbiology. He was the first to use the oil immersion lens, condenser, and microphotography in microscopy. His invention of the bacterial culture method using agar and glass plates (later developed as the Petri dish by his assistant Julius Richard Petri) made him the first to grow bacteria in the laboratory. In appreciation of his work, he was appointed to government advisor at the Imperial Health Office in 1880, promoted to a senior executive position (Geheimer Regierungsrat) in 1882, Director of Hygienic Institute and Chair (Professor of hygiene) of the Faculty of Medicine at Berlin University in 1885, and the Royal Prussian Institute for Infectious Diseases (later renamed Robert Koch Institute after his death) in 1891.

The methods Koch used in bacteriology led to the establishment of a medical concept known as Koch's postulates, four generalized medical principles to ascertain the relationship of pathogens with specific diseases. The concept is still in use in most situations and influences subsequent epidemiological principles such as the Bradford Hill criteria. A major controversy followed when Koch discovered tuberculin as a medication for tuberculosis which was proven to be ineffective, but developed for diagnosis of tuberculosis after his death. For his research on tuberculosis, he received the Nobel Prize in Physiology or Medicine in 1905. The day he announced the discovery of the tuberculosis bacterium, 24 March 1882, has been observed by the World Health Organization as "World Tuberculosis Day" every year since 1982.

Early life and education
Koch was born in Clausthal, Germany, on 11 December 1843, to Hermann Koch (1814–1877) and Mathilde Julie Henriette (née Biewend; 1818–1871). His father was a mining engineer. He was the third of thirteen siblings. He excelled academically from an early age. Before entering school in 1848, he had taught himself how to read and write. He completed secondary education in 1862, having excelled in science and math.

At the age of 19, in 1862, Koch entered the University of Göttingen to study natural science. He took up mathematics, physics and botany. He was appointed assistant in the university's Pathological Museum. After three semesters, he decided to change his area of study to medicine, as he aspired to be a physician. During his fifth semester at the medical school, Jacob Henle, an anatomist who had published a theory of contagion in 1840, asked him to participate in his research project on uterine nerve structure. This research won him a research prize from the university and enabled him to briefly study under Rudolf Virchow, who was at the time considered "Germany's most renowned physician". In his sixth semester, Koch began to research at the Physiological Institute, where he studied the secretion of succinic acid, which is a signalling molecule that is also involved in the metabolism of the mitochondria. This would eventually form the basis of his dissertation. In January 1866, he graduated from the medical school, earning honours of the highest distinction, maxima cum laude.

Anthrax
Robert Koch is widely known for his work with anthrax, discovering the causative agent of the fatal disease to be Bacillus anthracis. After officially becoming a district physician in Wollstein (today's Wolsztyn), Poland, in 1872, Robert began to delve into the disease called Anthrax. Near Wollstein, anthrax disease was regularly taking the lives of humans and livestock without evidence explaining why. Eventually, in 1876, Koch was able to make an incredible discovery that anthrax was triggered by one singular pathogen. Koch’s discovery of the dormant stage, the anthrax spores, allowed him to successfully unravel the mystery behind the anthrax disease. By gaining a better understanding of this pathogen, he was able to shed light on the bacterium’s remarkable resistance to environmental factors (“Robert Koch – Nobel Lecture” 2018). This groundbreaking achievement marked Koch as the pioneer scientist to discover that a microscopic organism was causing a disease to spread. His findings were especially impressive as they were done in a poorly equipped laboratory in Wollstein.

He published the discovery in a booklet as "Die Ätiologie der Milzbrand-Krankheit, Begründet auf die Entwicklungsgeschichte des Bacillus Anthracis" (The Etiology of Anthrax Disease, Based on the Developmental History of Bacillus Anthracis) in 1876 while working at in Wöllstein. His publication in 1877 on the structure of anthrax bacterium marked the first photography of a bacterium. He discovered the formation of spores in anthrax bacteria, which could remain dormant under specific conditions. However, under optimal conditions, the spores were activated and caused disease. To determine this causative agent, he dry-fixed bacterial cultures onto glass slides, used dyes to stain the cultures, and observed them through a microscope. His work with anthrax is notable in that he was the first to link a specific microorganism with a specific disease, rejecting the idea of spontaneous generation and supporting the germ theory of disease.

Career
After graduation in 1866, Koch briefly worked as an assistant in the General Hospital of Hamburg. In October of that year, he moved to Idiot's Hospital of Langenhagen, near Hanover, as a general physician. In 1868, he moved to Neimegk and then to Rakwitz in 1869. As the Franco-Prussian War started in 1870, he enlisted in the German army as a volunteer surgeon in 1871 to support the war effort. He was discharged a year later and was appointed as a district physician (Kreisphysikus) in Wollstein in Prussian Posen (now Wolsztyn, Poland). As his family settled there, his wife gave him a microscope as a birthday gift. With the microscope, he set up a private laboratory and started his career in microbiology.

Koch began conducting research on microorganisms in a laboratory connected to his patient's examination room. His early research in this laboratory yielded one of his major contributions to the field of microbiology, as he developed the technique of growing bacteria. Furthermore, he managed to isolate and grow selected pathogens in a pure laboratory culture. His discovery of the anthrax bacillus (later named Bacillus anthracis) hugely impressed Ferdinand Julius Cohn, professor at the University of Breslau (now the University of Wrocław), who helped him publish the discovery in 1876. Cohn had established the Institute of Plant Physiology and invited Koch to demonstrate his new bacterium there in 1877. Koch was transferred to Breslau as district physician in 1879. A year after, he left for Berlin when he was appointed a government advisor at the Imperial Health Office, where he worked from 1880 to 1885. Following his discovery of the tuberculosis bacterium, he was promoted to Geheimer Regierungsrat, a senior executive position, in June 1882.

In 1885, Koch received two appointments as an administrator and professor at Berlin University. He became Director of Hygienic Institute and Chair (Professor of hygiene) of the Faculty of Medicine. In 1891, he relinquished his professorship and became a director of the Royal Prussian Institute for Infectious Diseases (now the Robert Koch Institute) which consisted of a clinical division and beds for the division of clinical research. For this, he accepted harsh conditions. The Prussian Ministry of Health insisted after the 1890 scandal with tuberculin, which Koch had discovered and intended as a remedy for tuberculosis, that any of Koch's inventions would unconditionally belong to the government and he would not be compensated. Koch lost the right to apply for patent protection. In 1906, he moved to East Africa to research a cure for trypanosomiasis (sleeping sickness). He established the Bugula research camp where up to 1000 people a day were treated with the experimental drug Atoxyl.

Techniques in bacteria study
Robert Koch made two important developments in microscopy; he was the first to use an oil immersion lens and a condenser that enabled smaller objects to be seen. In addition, he was also the first to effectively use photography (microphotography) for microscopic observation. He introduced the "bedrock methods" of bacterial staining using methylene blue and Bismarck (Vesuvin) brown dye. In an attempt to grow bacteria, Koch began to use solid nutrients such as potato slices. Through these initial experiments, Koch observed individual colonies of identical, pure cells. He found that potato slices were not suitable media for all organisms, and later began to use nutrient solutions with gelatin. However, he soon realized that gelatin, like potato slices, was not the optimal medium for bacterial growth, as it did not remain solid at 37 °C, the ideal temperature for growth of most human pathogens. And also many bacteria can hydrolyze gelatin making it a liquid. As suggested to him by his post-doctoral assistant Walther Hesse, who got the idea from his wife Fanny Hesse, in 1881, Koch started using agar to grow and isolate pure cultures. Agar is a polysaccharide that remains solid at 37 °C, is not degraded by most bacteria, and results in a stable transparent medium.

Development of Petri dish
Koch's booklet published in 1881 titled "Zur Untersuchung von Pathogenen Organismen" (Methods for the Study of Pathogenic Organisms) has been known as the "Bible of Bacteriology." In it he described a novel method of using glass slide with agar to grow bacteria. The method involved pouring a liquid agar onto the glass slide and then spreading a thin layer of gelatin over it. The gelatin made the culture medium solidify, in which bacterial samples could be spread uniformly. The whole bacterial culture was then put on a glass plate together with a small wet paper. Koch named this container as feuchte Kammer (moist chamber). The typical chamber was a circular glass dish 20 cm in diameter and 5 cm in height and had a lid to prevent contamination. The glass plate and the transparent culture media made observation of the bacterial growth easy.

Koch publicly demonstrated his plating method at the Seventh International Medical Congress in London in August 1881. There, Louis Pasteur exclaimed, "C'est un grand progrès, Monsieur!" ("What a great progress, Sir!") It was using Koch's microscopy and agar-plate culture method that his students discovered new bacteria. Friedrich Loeffler discovered the bacteria of glanders (Burkholderia mallei) in 1882 and diphtheria (Corynebacterium diphtheriae) in 1884; and Georg Theodor August Gaffky, the bacterium of typhoid (Salmonella enterica) in 1884. Koch's assistant Julius Richard Petri developed an improved method and published it in 1887 as "Eine kleine Modification des Koch’schen Plattenverfahrens" (A minor modification of the plating technique of Koch). The culture plate was given an eponymous name Petri dish. It is often asserted that Petri developed a new culture plate, but this was not so. He simply discarded the use of glass plate and instead used the circular glass dish directly, not just as a moist chamber, but as the main culture container. This further reduced the chances of contaminations. It would also have been appropriate if the name "Koch dish" had been given.

Tuberculosis
During his time as the government advisor with the Imperial Health Agency in Berlin in the 1880s, Koch became interested in tuberculosis research. At the time, it was widely believed that tuberculosis was an inherited disease. However, Koch was convinced that the disease was caused by a bacterium and was infectious. In 1882, he published his findings on tuberculosis, in which he reported the causative agent of the disease to be the slow-growing Mycobacterium tuberculosis. He published the discovery as "Die Ätiologie der Tuberkulose" (The Etiology of Tuberculosis), and presented before the German Physiological Society at Berlin on 24 March 1882. Koch said,"When the cover-glasses were exposed to this staining fluid [methylene blue mixed with potassium hydroxide] for 24 hours, very fine rod-like forms became apparent in the tubercular mass for the first time, having, as further observations showed, the power of multiplication and of spore formation and hence belonging to the same group of organisms as the anthrax bacillus... Microscopic examination then showed that only the previously blue-stained cell nuclei and detritus became brown, while the tubercle bacilli remained a beautiful blue."

There was no particular reaction to this announcement. Eminent scientists such as Rudolf Virchow remained sceptical. Virchow clung to his theory that all diseases are due to faulty cellular activities. On the other hand, Paul Ehrlich later recollected that this moment was his "single greatest scientific experience." Koch expanded the report and published it under the same title as a booklet in 1884, in which he concluded that the discovery of tuberculosis bacterium fulfilled the three principles, eventually known as Koch's postulates, which were formulated by his assistant Friedrich Loeffler in 1883, saying:"All these factors together allow me to conclude that the bacilli present in the tuberculous lesions do not only accompany tuberculosis, but rather cause it. These bacilli are the true agents of tuberculosis."

Cholera
In August 1883, the German government sent a medical team led by Koch to Alexandria, Egypt, to investigate a cholera epidemic there. Koch soon found that the intestinal mucosa of people who died of cholera always had bacterial infection, yet could not confirm whether the bacteria were the causative pathogens. As the outbreak in Egypt declined, he was transferred to Calcutta (now Kolkata) India, where there was a more severe outbreak. He soon found that the river Ganges was the source of cholera. He performed autopsies of almost 100 bodies, and found in each bacterial infection. He identified the same bacteria from water tanks, linking the source of the infection. He isolated the bacterium in pure culture on 7 January 1884. He subsequently confirmed that the bacterium was a new species, and described as "a little bent, like a comma." His experiment using fresh blood samples indicated that the bacterium could kill red blood cells, and he hypothesized that some sort of poison was used by the bacterium to cause the disease. In 1959, Indian scientist Sambhu Nath De discovered this poison, the cholera toxin. Koch reported his discovery to the German Secretary of State for the Interior on 2 February, and published it in the Deutsche Medizinische Wochenschrift (German Medical Weekly) the following month.

Although Koch was convinced that the bacterium was the cholera pathogen, he could not entirely establish critical evidence the bacterium produced the symptoms in healthy subjects (following Koch's postulates). His experiment on animals using his pure bacteria culture did not cause the disease, and correctly explained that animals are immune to human pathogen. The bacterium was then known as "the comma bacillus", and scientifically as Bacillus comma. It was later realised that the bacterium was already described by an Italian physician Filippo Pacini in 1854, and was also observed by the Catalan physician Joaquim Balcells i Pascual around the same time. But they failed to identify the bacterium as the causative agent of cholera. Koch's colleague Richard Friedrich Johannes Pfeiffer correctly identified the comma bacillus as Pacini's vibrioni and renamed it as Vibrio cholera in 1896.

Tuberculosis treatment and tuberculin
Koch gave much of his research attention to tuberculosis throughout his career. After medical expeditions to various parts of the world, he again focussed on tuberculosis from the mid-1880s. By that time the Imperial Health Office was carrying out a project for disinfection of sputum of tuberculosis patients. Koch experimented with arsenic and creosote as possible disinfectants. These chemicals and other available drugs did not work. His report in 1883 also mentioned a failed experiment in an attempt to make a tuberculosis vaccine. By 1888, Koch turned his attention to synthetic dyes as antibacterial chemicals. He developed a method for examining antibacterial activity by mixing the gelatin-based culture media with a yellow dye, auramin. His notebook indicates that by February 1890, he tested hundreds of compounds. In one of such tests, he found that an extract from the tuberculosis bacterium culture dissolved in glycerine could cure tuberculosis in guinea pigs. Based on a series of experiments from April to July 1891, he could conclude that the extract did not kill the tuberculosis bacterium, but destroyed (by necrosis) the infected tissues, thereby depriving bacterial growth. He made a vague announcement in August 1890 at the Tenth International Medical Congress in Berlin, saying, In a communication which I made a few months ago to the International Medical Congress [in London in 1881], I described a substance of which the result is to make laboratory animals insensitive to inoculation of tubercle bacilli, and in the case of already infected animals, to bring the tuberculous process to a halt.

I can tell […] that much, that guinea pigs, which are highly susceptible to the disease [tuberculosis], no longer react upon inoculation with tubercle virus [bacterium] when treated with that substance and that in guinea pigs, which are sick (with tuberculosis), the pathological process can be brought to a complete standstill. By November 1890, Koch demonstrated the effectiveness of the extract in treating humans by administering the vaccine through the Bacillus Calmette-Guerin (BCG) technique. This absorbs the vaccine through the skin by means of multiple shallow punctures on the skin and many patients and doctors went to Berlin to get Koch's remedy. While this was effective in humans, his experiments also revealed that when the substance was inoculated into his tuberculosis-infected test guinea pigs, they presented with severe symptoms. This outcome, characterized by an exaggerated immune response, coined the term “Koch’s phenomenon.” This is known as an extreme skin reaction that manifests itself at the BCG vaccination site within a few days after the vaccine is administered to an individual infected with tuberculosis. When a normal guinea pig was inoculated with pure tubercle bacillus, the wound would close rapidly and heal within several days. Afterwards, the site of the injection would open and form an ulcer until the animal died. However, if the same inoculated culture was injected into a guinea pig that was previously infected with tuberculosis, the site of the injection becomes dark, and eventually heals normally and quickly (Moreland, 2024). The uncertainty in the chemical nature coined the term phenomenon in the name “Koch’s phenomenon.”

Koch published his experiments in the 15 January 1891 issue of Deutsche Medizinische Wochenschrift, and The British Medical Journal immediately published the English version simultaneously. The English version was also reproduced in Nature, and The Lancet in the same month. The Lancet presented it as "glad tidings of great joy." Koch simply referred to the medication as "brownish, transparent fluid." Josephs Pohl-Pincus had used the name tuberculin in 1844 for tuberculosis culture media, and Koch subsequently adopted as "tuberkulin."

The first report on the clinical trial in 1891 was disappointing. By then 1061 patients with tuberculosis of internal organs and of 708 patients with tuberculosis of external tissues were given the treatment. An attempt to use tuberculin as a therapeutic drug is regarded as Koch's "greatest failure." With it his reputation greatly waned. But he devoted the rest of his life trying to make tuberculin as a usable medication. His discovery was not a total failure: the substance is now used to test for hypersensitivity in tuberculosis patients.

Acquired immunity
Koch observed the phenomenon of acquired immunity. On 26 December 1900, he arrived as part of an expedition to German New Guinea, which was then a protectorate of the German Reich. Koch serially examined the Papuan people, the indigenous inhabitants, and their blood samples and noticed they contained Plasmodium parasites, the cause of malaria, but their bouts of malaria were mild or could not even be noticed, i.e. were subclinical. On the contrary, German settlers and Chinese workers, who had been brought to New Guinea, fell sick immediately. The longer they had stayed in the country, however, the more they too seemed to develop a resistance against it.

Koch's postulates
During his time as government advisor, Koch published a report on how he discovered and experimentally showed tuberculosis bacterium as the pathogen of tuberculosis. He described the importance of pure cultures in isolating disease-causing organisms and explained the necessary steps to obtain these cultures, methods which are summarized in Koch's four postulates. Koch's discovery of the causative agent of anthrax led to the formation of a generic set of postulates which can be used in the determination of the cause of most infectious diseases. These postulates, which not only outlined a method for linking cause and effect of an infectious disease but also established the significance of laboratory culture of infectious agents, became the "gold standard" in infectious diseases.

Although Koch worked out the principles, he did not formulate the postulates, which were introduced by his assistant Friedrich Loeffler. Loeffler, reporting his discovery of diphtheria bacillus in 1883, stated three postulates as follows:  From 424:  "Wenn nun die Diphtherie eine durch Mikroorganismen bedingte Krankheit ist, so müssen sich auch bei ihr jene drei Postulate erfüllen lassen, deren Erfüllung für den stricten Beweis der parasitäten Natur einer jeden derartigen Krankheit unumgänglich nothwendig ist: 1)  Es müssen constant in den local erkrankten Parteien Organismen in typischer Anordnung nachgewiesen werden. 2)  Die Organismen, welchen nach ihrem Verhalten zu den erkrankten Theilen eine Bedeutung für das Zustandekommen dieser Veränderungen beizulegen wäre, müssen isolirt und rein gezüchtet werden. 3)  Mit den Reinculturen muss die Krankheit experimentell wieder erzeugt werden können." (Now if diphtheria is a disease that's caused by microorganisms, then it must also be able to fulfil those three postulates whose fulfilment is absolutely necessary for the strict proof of the parasitic nature of any such disease: 1) In the given diseased patients, there must always be shown [to be present] organisms in typical disposition. 2)  The organisms to which one would attribute — according to their behaviour in the diseased parts — a relevance for the occurrence of these changes, must be isolated and cultured in pure form. 3) The disease must be able to be reproduced experimentally via pure cultures.)
 * 1. The organism must always be present in every case of the disease, but not in healthy individuals.
 * 2. The organism must be isolated from a diseased individual and grown in pure culture.
 * 3. The pure culture must cause the same disease when inoculated into a healthy, susceptible individual.

The fourth postulate was added by an American plant pathologist Erwin Frink Smith in 1905, and is stated as:

 * 4. The same pathogen must be isolated from the experimentally infected individuals.

Personal life
In July 1867, Koch married Emma (Emmy) Adolfine Josephine Fraatz, and the two had a daughter, Gertrude, in 1868. Their marriage ended after 26 years in 1893, and later that same year, he married actress Hedwig Freiberg (1872–1945).

On 9 April 1910, Koch suffered a heart attack and never made a complete recovery. On 27 May, three days after giving a lecture on his tuberculosis research at the Prussian Academy of Sciences, Koch died in Baden-Baden at the age of 66. Following his death, the Institute named its establishment after him in his honour. He was irreligious.

Awards and honours
Koch was made a Knight Grand Cross in the Prussian Order of the Red Eagle on 19 November 1890, and was elected a Foreign Member of the Royal Society (ForMemRS) in 1897. In 1905, he was awarded the Nobel Prize in Physiology and Medicine "for his investigations and discoveries in relation to tuberculosis." In 1906, research on tuberculosis and tropical diseases won him the Order Pour le Merite and in 1908, the Robert Koch Medal, established to honour the greatest living physicians. Emperor Wilhelm I awarded him the Order of the Crown, 100,000 marks and appointment as Privy Imperial Councillor, Surgeon-General of Health Service, and Fellow of the Science Senate of Kaiser Wilhelm Society.

Koch established the Royal Prussian Institute for Infectious Diseases in Berlin in 1891. After his death, it was renamed Robert Koch Institute in his honour.

The World Health Organization has observed "World Tuberculosis Day" every 24 March since 1982 to commemorate the day Koch discovered the tuberculosis bacterium.

Koch's name is one of 23 from the fields of hygiene and tropical medicine featured on the frieze of the London School of Hygiene & Tropical Medicine building in Keppel Street, Bloomsbury.

A large marble statue of Koch stands in a small park known as Robert Koch Platz, just north of the Charity Hospital, in the Mitte section of Berlin. His life was the subject of a 1939 German-produced motion picture that featured Oscar-winning actor Emil Jannings in the title role. On 10 December 2017, Google showed a Doodle in celebration of Koch's birthday.

Koch and his relationship to Paul Ehrlich, who developed a mechanism to diagnose TB, were portrayed in the 1940 movie Dr. Ehrlich's Magic Bullet.

Louis Pasteur
At their first meeting at the Seventh International Medical Congress in London in August 1881, Koch and Pasteur were friendly towards each other. But the rest of their careers followed with scientific disputes. The conflict started when Koch interpreted his discovery of anthrax bacillus in 1876 as causality, that is, the germ caused the anthrax infections. Although his postulates were not yet formulated, he did not establish the bacterium as the cause of the disease: it was an inference. Pasteur therefore argued that Koch's discovery was not the full proof of causality, but Pasteur's anthrax vaccine developed in 1881 was. Koch published his conclusion in 1881 with a statement: "anthrax never occurs without viable anthrax bacilli or spores. In my opinion no more conclusive proof can be given that anthrax bacilli are the true and only cause of anthrax," and that vaccination such as claimed by Pasteur would be impossible. To prove his vaccine, Pasteur sent his assistant Louis Thuillier to Germany for demonstration and disproved Koch's idea. They had a heated public debate at the International Congress for Hygiene in Geneva in 1882, where Koch criticised Pasteur's methods as "unreliable," and claimed they "are false and [as such ] they inevitably lead to false conclusions." Koch later continued to attack Pasteur, saying, "Pasteur is not a physician, and one cannot expect him to make sound judgments about pathological processes and the symptoms of disease."

Tuberculin
When Koch discovered tuberculin in 1890 as a medication for tuberculosis, he kept the experiment secret and avoided disclosing the source. It was only after a year under public pressure that he publicly announced the experiment and the source. Clinical trials with tuberculin were disastrous and complete failures. Rudolf Virchow's autopsy report of 21 subjects treated with tuberculin to the Berlin Medical Society on 7 January 1891 revealed that instead of healing tuberculosis, the subjects died because of the treatment. One week later, Koch publicised that the drug was a glycerine extract of a pure cultivation of the tuberculosis bacilli. The German official report in late 1891 declared that tuberculosis was not cured with tuberculin. From this moment onwards, Koch's prestige fell apart. The reason for his initial secrecy was due to an ambition for monetary benefits for the new drug, and with that establishment of his own research institute. Since 1885, he had tried to leave government service and create an independent state-run institute of his own. Following the disappointment, he was released from the University of Berlin and forced to work as Director of the Royal Prussian Institute for Infectious Diseases, a newly established institute, in 1891. He was prohibited from working on tuberculin and from claiming patent rights in any of his subsequent works.

Human and cattle tuberculosis
Koch initially believed that human (Mycobacterium tuberculosis) and cattle tuberculosis bacilli (now called Mycobacterium bovis) were different pathogens when he made the discovery in 1882. Two years later, he revoked that position and asserted that the two bacilli were the same type. This later assumption was taken as a fact in veterinary practice. Based on it, legislations were made in the US for the inspection of meat and milk. In 1898, an American veterinarian Theobald Smith published a detailed comparative study and found that the tuberculosis bacteria are different based on their structure, growth patterns, and pathogenicity. In addition, he also discovered that there were variations in each type. In his conclusion, he made two important points:

 * 1) Human tuberculosis bacillus cannot infect cattle.
 * 2) But cattle bacillus may infect humans since it is very pathogenic.

By that time, there was evidence that cattle tuberculosis was transmitted to humans through meat and milk. Upon these reports, Koch conceded that the two bacilli were different but still advocated that cattle tuberculosis was of no health concern. Speaking at the Third International Congress on Tuberculosis, held in London in July 1901, he said that cattle tuberculosis is not dangerous to humans and there is no need for medical attention. He said, "I therefore consider it unnecessary to take any measures against this form of TB. The fight against TB clearly has to concentrate on the human bacillus." Chair of the congress, Joseph Lister reprimanded Koch and explained the medical evidence of cattle tuberculosis in humans.

The 1902 Nobel Prize in Physiology or Medicine
The Nobel Committee selected the 1902 Nobel Prize in Physiology or Medicine to be awarded for the discovery of the transmission of malaria. But it could not make the final decision on whom to give it to — the British surgeon Ronald Ross or the Italian biologist Giovanni Battista Grassi. Ross had discovered that the human malarial parasite was carried by certain mosquitoes in 1897, and the next year that bird malaria could be transmitted from infected to healthy birds by the bite of a mosquito. Grassi had discovered Plasmodium vivax and the bird malaria parasite, and towards the end of 1898 the transmission of Plasmodium falciparum between humans through mosquitoes Anopheles claviger. To the surprise of the Nobel Committee, the two nominees exchanged polemic arguments against each other publicly justifying the importance of their own works. Robert Koch was then appointed as a "neutral arbitrator" to make the final decision. To his disadvantage, Grassi had criticised Koch on his malaria research in 1898 during an investigation of the epidemic, while Ross had established a cordial relationship with Koch. Ross was selected for the award, as Koch "threw the full weight of his considerable authority in insisting that Grassi did not deserve the honour".

Hogshead

A hogshead (abbreviated "hhd", plural "hhds") is a large cask of liquid (or, less often, of a food commodity). More specifically, it refers to a specified volume, measured in either imperial or US customary measures, primarily applied to alcoholic beverages, such as wine, ale, or cider.

Etymology

English philologist Walter William Skeat (1835–1912) noted the origin is to be found in the name for a cask or liquid measure appearing in various forms in Germanic languages, in Dutch oxhooft (modern okshoofd), Danish oxehoved, Old Swedish oxhuvud, etc. The Encyclopædia Britannica of 1911 conjectured that the word should therefore be "oxhead", "hogshead" being a mere corruption.

Varieties and standardisation
A tobacco hogshead was used in British and American colonial times to transport and store tobacco. It was a very large wooden barrel. A standardized hogshead measured 48 in long and 30 in in diameter at the head (at least 550 L, depending on the width in the middle). Fully packed with tobacco, it weighed about 1000 lb.

A  hogshead in Britain contains about 300 L.

The Oxford English Dictionary (OED) notes that the hogshead was first standardized by an act of Parliament (2 Hen. 6. c. 14) in 1423, though the standards continued to vary by locality and content. For example, the OED cites an 1897 edition of Whitaker's Almanack, which specified the gallons of wine in a hogshead varying most particularly across fortified wines: claret/Madeira 46 impgal, port 57 impgal, sherry 54 impgal. The American Heritage Dictionary claims that a hogshead can consist of anything from (presumably) 62.5 to 140 USgal. A hogshead of Madeira wine was approximately equal to 45–48 gallons (0.205–0.218 m3). A hogshead of brandy was approximately equal to 56–61 gallons (0.255–0.277) m3.

Eventually, a hogshead of wine came to be 63 USgal, while a hogshead of beer or ale is 54 gallons (250 L if old beer/ale gallons, 245 L if imperial).

A hogshead was also used as unit of measurement for sugar in Louisiana for most of the 19th century. Plantations were listed in sugar schedules by the number of hogsheads of sugar or molasses produced. Used for sugar in the 18th and 19th centuries in the British West Indies, a hogshead weighed on average 16 cwt / 812kg. A hogshead was also used for the measurement of herring fished for sardines in Blacks Harbour, New Brunswick and Cornwall.
