Automaker Henry Ford began to test farm crops for their industrial potential around 1930, and soon settled on hemp and the soybean as particularly promising (the famous Hemp Body or "Soybean Car"). The Ford Motor Company used soybeans in such parts as gearshift knobs and horn buttons, and hemp for the body of the car. The automobile was designed to run on hemp diesel. Ford Motor Company accessed these innovations via the discovery and ingenuity of George Washington Carver, Tuskegee Scientist and Father of Chemurgy.
