Crawford County, Iowa

In 1865, four eastern townships of Monona County were separated from that county and incorporated into Crawford County's boundary.

After several adjustments and reorganizations, the present arrangement of Crawford County townships was completed in June 1872.

Étienne Bézout

Étienne Bézout (31 March 1730 – 27 September 1783) was a French mathematician who was born in Nemours, Seine-et-Marne, France, and died in Avon (near Fontainebleau), France.

Work
In 1758 Bézout was elected an adjoint in mechanics of the French Academy of Sciences. Besides numerous minor works, he wrote a Théorie générale des équations algébriques, published at Paris in 1779, which in particular contained much new and valuable matter on the theory of elimination and symmetrical functions of the roots of an equation: he used determinants in a paper in the Histoire de l'académie royale, 1764, but did not treat the general theory.

Publications

Legacy
After his death, a statue was erected in his birth town, Nemours, to commemorate his achievements.

In 2000, the minor planet 17285 Bezout was named after him.

Chickasaw County, Iowa

Chickasaw County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 12,012. Its county seat is New Hampton. The county was named for the southern Indian Nation whose chief was Bradford.

History
Chickasaw County was founded in January 1851. It was named after the Chickasaw tribe, which lived in the Southern United States at the time.

The first nonindigenous settlers arrived in 1848 and the first county seat was from 1854 in Bradford, in the southwestern corner of the county. In the spring of 1857, the seat was moved to New Hampton, located near the geographic center, and was then called Chickasaw Center. The first county offices were housed in private houses and in the school building. The first courthouse, a wood-frame building, was erected in 1865. That building was enlarged in 1876, but a fire on March 26, 1880, destroyed it (townspeople managed to save the records). A brick/stone replacement structure was completed in 1881, and included a soaring clock tower. This building was enlarged in 1905 and again in 1906, but by the twenties it again was too small. The present structure, featuring Bedford stone, was built in 1929 and put into use in 1930.

Geography
According to the US Census Bureau, the county has a total area of 506 sqmi, of which 504 sqmi is land and 1.3 sqmi (0.3%) is water.

Cass County, Iowa

Cass County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 13,127. Its county seat is Atlantic. It was named to honor Lewis Cass, who was the 1848 Democratic nominee for president.

History
Cass County is named in honor of Lewis Cass, a Michigan senator and an unsuccessful Democratic candidate for the presidency in 1848. The county was established within its present boundaries in 1851 and originated in 1853. Religious persecution was responsible for bringing the first people of European ancestry to Cass County. The Mormons, fleeing from Illinois, were the earliest settlers, and established a community at Indiantown in 1846.

At Indiantown, two of the three commissioners selected to locate a county seat were chosen. The site they chose was 1 mi from Indiantown and named Lewis. Most of the people and businesses in Indian Town moved to Lewis shortly after it was laid out. In 1856, a frame courthouse was built, and eight years later a small stone building was completed for the county treasurer's office. In 1857, there was an attempt to relocate the county seat to Grove City; it was unsuccessful. On October 20, 1869, after a due canvass of the vote on the re-location of the county seat, the Board declared the city of Atlantic the county seat and ordered the county officers to that place. In 1872, the first courthouse built in Atlantic was completed. Until it was completed county offices were held in various empty buildings. Ten years later the county built its second courthouse at Atlantic. The $65,000 building was destroyed by a fire in 1932. The fire started in the clock tower and gutted all of the second floor. Most of the county records and equipment were saved.

The present, fourth, courthouse was completed in 1934. While it was being built, county offices were located in the Atlantic Motors building, where an attempted robbery of the treasurer's safe took place. The robbers were interrupted and escaped, but without any money. The final cost of the fourth courthouse was $130,000: $65,000 came from a county bond issue, $46,500 from insurance and the remaining was covered by a Public Works Administration federal grant. The concrete and brick building is three stories high. It was dedicated on December 26, 1934, with the main speaker being the Governor of Iowa, Clyde L. Herring. The Board of Supervisors approved a new jail addition, which was dedicated in 1984.

Geography
According to the U.S. Census Bureau, the county has a total area of 565 sqmi, of which 564 sqmi is land and 0.7 sqmi (0.1%) is water.

Calhoun County, Iowa

Calhoun County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 9,927. Its county seat is Rockwell City.

History
Calhoun County was formed on January 15, 1851, from open land originally named Fox County. It was renamed in 1853 after the seventh US vice president secessionist John C. Calhoun. When the tracks of the Illinois Central Railroad were laid through the county in 1870, the county seat was moved from Lake City to Rockwell City. The first train reached Rockwell City on August 7, 1882, and the population count doubled in the same year. The first courthouse, built of wood, burned to the ground in 1884 and the county government moved into a nearby hotel. In 1913, the current courthouse was built.

On July 6, 1893, Pomeroy was struck by a tornado that measured F5 on the Fujita scale. With a damage path 500 yd wide and 55 mi long, the tornado destroyed about 80% of the homes in Pomeroy. The tornado killed 71 people and injured 200.

Geography
According to the U.S. Census Bureau, the county has a total area of 572 sqmi, of which 570 sqmi is land and 2.1 sqmi (0.4%) is water.

Ecology
Calhoun County is located entirely within the Des Moines Lobe of the Western Corn Belt Plains ecoregion, as defined by the United States Environmental Protection Agency (EPA). One of the flattest regions in Iowa, the Des Moines Lobe ecoregion is a distinctive area naturally defined by Wisconsin glaciation but modified by humans for extensive agriculture. In general, the land is level to gently rolling with some areas of relief defined by glacial features like moraines, hummocky knobs, and kettles, and outwash deposits. The lobe does not have any loess deposits like the Loess Hills to the west.

The stream network is poorly developed and widely spaced, with major rivers carving valleys that are relatively deep and steep-sided. Almost all of the natural lakes of Iowa are found in the northern part of this region (the Iowa Great Lakes). Most of the region has been converted from wet prairie to agricultural use with substantial surface water drainage. Only a small fraction of the wetlands remain, and many natural lakes have been drained as a result of agricultural drainage projects via drainage tiles or ditches.

Butler County, Iowa

Butler County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 14,334. Its county seat is Allison. The county was organized in 1854 and named for General William O. Butler.

History
Butler County was formed on January 15, 1851, from open land. It was named after Kentucky native William Orlando Butler, a general and hero of the Mexican–American War, who ran as Vice President of the United States in 1848. Until 1854, the county was governed by other counties. Only at this time did it have enough inhabitants to establish its own local government. The first court proceedings were conducted in a small log cabin of a settler. In 1858, the first courthouse was completed in Clarksville. After it was sold shortly thereafter to the local school district, it was used as a schoolhouse from 1863 until 1903.

Clarksville was the first county seat, from 1854 to 1860, after which Butler Center became the seat. Because locals became disenchanted with Butler Center (partially because of its inaccessibility during the winter), Allison was made the county seat on January 10, 1881, after the tracks of the Dubuque and Dakota Railroad had been laid there.

Butler County is the only county in Iowa that does not have any stop lights, four-lane roads (US Highway or interstate), a hospital, or a movie theatre. There are also no national fast-food chains in Butler county.

Geography
According to the U.S. Census Bureau, the county has a total area of 582 sqmi, of which 580 sqmi is land and 1.6 sqmi (0.3%) is water.

Politics

Roosevelt in 1932 and 1936. Finally, the most recent occurrence was in 1996, when incumbent Bill Clinton won the county with a plurality, aided in part by a strong third party performance by Ross Perot; furthermore, Clinton only defeated Republican candidate Bob Dole in Butler County by only 25 votes and a slim margin of 0.38%. No Democrat has ever received more than 57% of the vote in the county's history.

Kier, between Fairbank and Littleton, appeared on many maps in the 19th century and early 20th century. The area is now settled by Amish. Several towns named Middlefield existed southeast of Winthrop, but none are populated today. Newtonville was located a few miles south of Monti. The houses at Castleville were later moved to Aurora.

Boone County, Iowa

Boone County is a county in the U.S. state of Iowa. As of the 2020 census, the population was 26,715. Its county seat is Boone.

Boone County comprises the Boone, IA Micropolitan Statistical Area, which is included in the Des Moines-Ames-West Des Moines, IA Combined Statistical Area.

History
The land that now forms Boone and several other Iowa counties was ceded by the Sac and Fox nation to the United States in a treaty signed on October 11, 1842.

On January 13, 1846, the legislative body of the Indiana Territory authorized creation of twelve counties in the Iowa Territory, with general descriptions of their boundaries. Boone County's name referred to Captain Nathan Boone, son of Daniel Boone, an American pioneer who formed the Wilderness Trail and founded the settlement of Boonesborough, Kentucky.

County residents selected Boonesboro as the county seat in 1851. The first building erected in the new settlement was a double log house, to be used as interim county office and courthouse. It was supplemented by a two–story building erected in 1856, then replaced by a three-story building in 1868.

The nearby settlement of Montana was incorporated in 1866, when a railway station was built there. It was renamed to Boone in 1871. It continued to grow, and it annexed the settlement of Boonesboro (which had also been incorporated in 1866) in 1887, thus becoming the county seat.

After the second courthouse became too small for the county's expanding populace, a new building (the present courthouse) replaced it. It was completed in 1917.

Geography
According to the U.S. Census Bureau, the county has a total area of 574 sqmi, of which 572 sqmi is land and 2.1 sqmi (0.4%) is water.
