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.
