George Washington Carver and Henry Ford at the Carver Nutrition Laboratory, Dearborn, Michigan, 1942

George Washington Carver and Henry Ford shared not only an interest in using agricultural products in industry ("chemurgy"), but also some quirky ideas about diet. Here, Carver and Ford share a sandwich of "weed spread," made with wild bergamot, narrow-leafed plantain, purslane, pigweed, milkweed, dandelion, lamb's quarters and wild radish. They shared this meal at Ford Motor Company's George Washington Carver Nutrition Laboratory during Carver's 1942 Dearborn visit.
