When the Wisconsin Central Railroad was building its line through the wilderness heading toward Lake Superior, it finished its 1872 construction season with rails completed to the site of today's Colby. The place was initially called "Section 53," but the railroad renamed the station in honor of Charles L. Colby, partner in the construction company that was building the railroad, and the son of the railroad's financier Gardner L. Colby. Colby is the birthplace of Colby cheese. A historical marker in downtown Colby commemorates the development of Colby cheese by Joseph Steinwand in 1874. Colby cheese is no longer made in the city of Colby, although a factory east of town cuts and packages it. The former Colby cheese factory west of the city is a dilapidated building.
