After the Black Hawk War was over in 1832, the United States government surveyed the west bank of the Rock River at the present-day site of Janesville. In the following years, settlers retraced the soldiers’ steps and developed Janesville along the Rock River. In the summer of 1835, the first settlers arrived. Inman and Holmes, living in Milwaukee then, set out on July 15th to search for land in the Rock River valley together. They came upon the remains of Black Hawk’s camp two days later. The settlers found the land to their liking, but there were no other settlers in the area, so they returned to Milwaukee to gather supplies and make settlement plans. A few months later, Inman, Holmes, Joshua, and George Follner returned to the Rock River banks. The first permanent structure on the present-day Janesville site was a log cabin. In December 1835, Samuel St. John and his family of five arrived at the house, and all nine settlers spent the winter together.
The following Spring, several land claims and “paper towns” were platted on lands near Inman’s cabin. The county seat was established in 1836 on a small plot of land owned by Henry Janes on the east bank of the Rock River, which today is marked by the intersection of Milwaukee and Main streets. Janes applied for a post office on the site, recommending himself as postmaster and calling it “Black Hawk.” Janes was appointed postmaster by Amass Kindle, then US Postmaster General, but the office was renamed Janesville.
As a county seat, Janesville was an influential government center. Water power development along the Rock River also contributed to the City’s early prosperity. Along the Rock River were built dams, bridges, lumber mills, grist mills, and woolen mills in the 1840s. Before the Civil War, wheat and three railroad lines propelled growth. Janesville was incorporated as a city in 1853. In the following decades, flour milling, woolen and cotton production, cigar, shoe, and brick manufacturing, stone quarrying, tobacco warehousing, agricultural implement manufacturing, and eventually automobile manufacturing contributed to the economy’s and population’s expansion. From a settlement of less than 300 people in 1840, Janesville grew to 3,000 in 1850, 8,789 in 1870, 13,185 in 1900, and 22,186 in 1925. In the 19th century, most of Janesville’s residents were natives of New York and New England. English, Irish, Scottish, and Welsh immigrants constituted the largest group of European immigrants.

#60 Early woolen mill, Janesville, 1870

PJanesville's first woolen mill built in 1849. Men, women, and child laborers stand in front of the stone three-story structure, said to be on the site of what became the Panoramic Corporation and thus the longest continuously occupied industrial site in the city. This may be the oldest photograph in existence showing a Janesville labor force at its place of employment. The mill was constructed in 1849 as the Whitaker Mill. F. A. Wheeler and Sons then ran it. Payne, Hastings, and Co. took over the mill sometime between 1866 and 1870. In 1873, the company was reorganized as the McLean Woolen Mills. Around the turn of the twentieth century, it became known as the Rock River Woolen Mills. The stone building in this photo burned down around 1881 and was replaced by a new structure which was still standing in 1982 as part of the Panoramic complex. A JANESVILLE GAZETTE article from March 11, 1871, described what went on on each floor of the mill: the lower level was used for storage.
