Lloyd Groff Copeman (born December 28, 1881 in Farmers Creek , Michigan , † July 5, 1956 ) was an American inventor with around 700 patents. Among other things, he designed the first electric stove.

He grew up on a farm in east Flint (Michigan) and studied mechanical engineering at the former Michigan Agricultural College ( Michigan State University ). Around 1906 he worked for the Washington Electric Company . During this time he developed an electric version of the gas stove. His first successful patent in 1906 was an electric thermostat for stoves, toasters and high-voltage lines. In 1912 he founded the Copeman Electric Stove Company in Flint to produce his Copeman Electric Stove . He sold the company to Westinghouse in 1917 .

In 1913 he developed the Automatic Toaster , which turned the toast over automatically. However, that invention was overtaken by the invention of the pop-up toaster in 1926.

In 1928 he made his most successful invention, the ice cube trays made of rubber, which he 500,000 US dollars earned.

In 1904 he married his wife Hazel, with whom he had three children: Lloyd Berger Copeman (1907–1968), Elizabeth Jane Copeman Gerlach (1918–1998) and Ruth Mary Copeman Ronstadt (1914–1982) (the mother of Linda Ronstadt ).
