History
Brookfield is west of Milwaukee in Waukesha County in an area originally inhabited by Potawatomi Indians. The first white settler, William Howe, arrived in 1820 with a Presidential Land Grant giving him title to the area. Soon after, Robert Curren bought a claim in 1836 and established a tavern and inn.
In May 1838, Jacques View Jr., with a large party of white settlers, led the local Potawatomi west. Caroline Quiner, the mother of Laura Ingalls Wilder, was born in a cabin in 1839 in what is now the City of Brookfield, near the current intersection of Brookfield Road and Davidson Road. By 1839, the population needed a schoolhouse, as the 1840 census showed a population of 148. In these 1840s, George Gebhardt started trading with the surrounding Potawatomi and Menominee neighbors. In 1843, Brookfield's first church, St. Dominic, was built by the Irish Catholic congregation. In 1848, the first telegraph lines were laid through Brookfield, towards Waukesha. Communication was made easier due to this. In 1849, cholera reached Brookfield, and one Laura Grover recalls, "The death-like stillness was appalling; nothing was seen but the death carts rolling round the streets gathering the recent dead... I believe there were fifty deaths from cholera that day." The same year, 64 Brookfield residents voted in favor of giving suffrage to black residents, and 0 the other way. In 1850, cholera again went through Brookfield, and according to one Earl Thayer, "The cholera returned... more terrible than the year before. People literally died walking along the streets. Official reports put the toll at over 300."
In 1850, the Milwaukee and Mississippi Railroad (now the Canadian Pacific Rail) built a railroad through the town, which in 1853 erected a depot, forming the Brookfield Junction. In the year 1850, the Town of Brookfield had 1,944 inhabitants and in land area covered 36 square miles. The town slowly grew over following years, with the economy being mostly agricultural, with Brookfield Junction serving as a commercial center for the surrounding farms. The Civil War had little effect on this town, despite the severe losses of members serving from the state. "More than 12,000 died: 3,802 were killed in action or died of wounds and 8,499 died from disease, exposure, and other causes." In 1867, a second rail depot was constructed, which still stands.
In the 1900s, Brookfield gained a new reputation. Waukesha County was called Cow County, U.S.A., as according to advertisers, they claimed that in the county there were more cows than people. This was, of course, fantastical, although there were cows. This did help cement Wisconsin's dairy reputation. The Spanish flu, killed many people in the area, but not as many as cholera had in the past. On May 31, 1914, a tornado hit, devastating the farmers and the rural area.
