Here's a brief history of the company Corteva Agriscience's seed business, which will now be known as SpinCo.
1926
Iowa-born Henry A. Wallace, a future U.S. vice president, leads a group that founds the Hi-Bred Corn Co. in Des Moines to produce and market new hybrid corn seed. The seed initially is produced on 40 acres Wallace bought in 1919 in what was then Grimes near Johnston, which will become the company's base.

Wallace steps away from the growing company to become President Franklin D. Roosevelt's secretary of agriculture but continues to advise Hi-Bred. Looking for a free mini puzzle? Play the USA TODAY Quick Cross now.
