Our Heritage

A True Pioneer

Company founder Henry A. Wallace knew a successful yield required more than planting straight rows. His early understanding of corn genetics was a game-changer for farmers who soon realized greater yield and productivity. Through the decades, DuPont Pioneer has remained true to Wallace’s vision, increasing productivity and profitability for our customers using technological innovation.
