Flint, Michigan. She was a granddaughter of
Lloyd Groff Copeman, a prolific inventor and holder of many patents. Copeman, with nearly 700 patents to his name, invented an early form of the toaster, many refrigerator devices, the grease gun, the first electric stove, and an early form of the microwave oven. His flexible rubber ice cube tray earned him millions of dollars in royalties.
