It was originally platted in 1865 one mile west of the present site by A. J. Burbank for land speculators; Burbank erected a three-story hotel on the townsite, and a post office opened, 1867-74. When the Chicago Great Western Railroad came in 1885, the railroad platted the new site, and the original townsite land was sold off for farming. A new post office was established in 1886.
