History
The town was named for its founder, Daniel Dimmick, who emigrated here from Mansfield, Connecticut by way of Hennepin, Illinois in 1833. The railroad was extended to Dimmick by the Illinois Central Railroad. In 1873, a rail depot was constructed to replace an earlier one that had fallen into disrepair and the town was platted. By 1876, the town was home to three stores and a blacksmith. A post office was established at Dimmick in 1877, and remained in operation until 1912. Passenger service continued until the early 1930s before being discontinued.References
