HAMMEL & HENKER COMPANY
Hammel & Henker Company.
Beginning operations on February 8, 1879, at Eighteenth and Pine STREETS, Hammel & Henker mill had a capacity of 150 barrels of flour daily or approximately 5,400 tons annually. The mill employed twelve, but most of the work was done by machinery. "Rooster" brand flours was the specialty of the company with wheat flour, rye flour, graham flour, buckwheat flour and pancake flour sold in Dubuque, Illinois, Wisconsin, and Iowa where competition with larger mills was less.
The last flour was processed at the mill in 1933 when production was entirely converted to feed processing. The mill burned down on May 12, 1943, but business continued selling equipment needed by farmers.
