Beet Sugar Factory Site

E. H. Dyer, 'father of the American beet sugar industry,' built the factory in 1870 on a corner of his farm. It began to process sugar beets on November 15, 1870, and produced 293 tons of sugar during its first operating season. The plant has since been completely rebuilt on the original site.
