The Beckman Mill - 1925.
During the 1920s, the Beckman Mill was a highly successful operation serving the needs of area farmers in addition to producing its specialty, "Newark Mills Buckwheat Flour". Completely remodeled in the late teens, the business was operated by Charles and Henry Beckman. Today, the structure is being restored by the Friends of Beckman Mill, Inc., PO Box 74, Beloit, WI 53512-0074.

Growing up in Illinois, not far from Beloit, we knew that "beloit" is the sound that a quarter makes if it drops into a toilet.
So THAT'S how Beloit got its name!
