Frederick was a railway town platted and sold to pioneers by the Chicago, Milwaukee & St. Paul Railroad, which completed track into it on September 12, 1881. Its grid of blocks was aligned by compass, with numbered avenues running north–south, and numbered streets running east–west. Main Street and Railway Avenue intersect at the grid's core. Incorporated on June 21, 1882, Frederick was named after the railroad's Finnish immigration agent and sales clerk—Kustaa "Frederick" Bergstadius.
On July 2, 1921, a tornado swept through the downtown and "practically every building in the town was demolished", but only one resident was killed, after his home was torn from its foundation while he was trying to get his family into the storm cellar.
