Recently CNN rand a bio of Linda Ronstadt and a blurb indicated her mother was born in Flint MI, as was I. It was also noted that her grandfather Lloyd Copeman held over 700 patents. He formed the Copeman Electric Stove Company in Flint MI in 1912, also invented the rubber ice cube tray. He sold the Stove Company to Westinghouse in 1917.
From Wikipedia
Lloyd Groff Copeman (December 28, 1881 – July 5, 1956)[1] was an American inventor who devised the first electric stove and the flexible rubber ice cube tray, among other products. He had nearly 700 patents to his name, and he claimed that he could walk into any store and find one of his inventions.[2]
Never would have guessed Linda Ronstadt had a connection to electric ranges and Flint MI.
