Near Mankato in Blue Earth County, Minnesota — The American Midwest (Upper Plains)
The Seppman wind mill produced flour until it fell victim to natural disasters and new milling technology.
Realizing the need for a local source of flour, Louis Seppman, a stone mason by trade, began construction of this mill in 1862. Two years later the mill was operational. On days with a favorable wind, Louis Seppman, could transform about 150 bushels of wheat a day into fairly good flour.
Natural Disasters Hamper Operations
Operation went well until 1873 when lightning struck, knocking off two of the arms and sails. These were replaced and operation continued until 1880 when a tornado again tore off two arms. These were not replaced but operation continued until 1890 when another storm finally damaged the structure beyond repair.
Extensive structural damage, together with competition from water and steam powered mills and the invention of the "roller process," made this windmill unprofitable to operate. It never produced flour again and closed in 1890.
