The Adams County Fair originated back in 1941 as a fall festival and livestock show. It was a one-day event held “on the square” in Mendon. While most events these days are held in the evening, at that time there were no night time activities. The original board officers were as follows: Vernon O’Brien, president; Harry Evans, vice president; Sidney Wright, secretary; and Walter Wessel, treasurer. Board members were: Virgil M. Conover, A. M. Parrick, Joel Dickerman, Lloyd M. Curry, Ralph Clair, Wilmer Cornwell, Ray Thyson and Glenn Mittelberg.
