The story

How it began

Eugene Sukup, a central-Iowa farmer, invented a stirring device to keep stored grain from spoiling and began building it in his machine shed near Sheffield in 1963.

That one product grew into Sukup Manufacturing Co., which the Sukup family built into the world's largest family-owned manufacturer of grain bins, dryers, and steel buildings — all from a town of a few hundred people.

Legacy

Legacy & philanthropy

Sukup made Sheffield, Iowa, a global address in agriculture, employing much of the surrounding countryside. The family also drew national attention for turning its grain-bin technology into the Safe T Home® — bins converted into durable housing for disaster and refugee relief.

The Sukup Family Foundation supports the community, and the family name adorns Iowa State's Sukup End Zone Club at Jack Trice Stadium.
