Schoep's Ice Cream was founded by E.J. Schoephoester in 1928. Schoephoester produced and sold the ice cream in his grocery store. By 1937 Schoep's Ice Cream had become well known locally and E. B. Schoephoester sold his company to Peter B. Thomsen, a butter maker. The company has been kept in the Thomsen family, and as of 2008 it was owned in part by nineteen members of the Thomsen family.
