Antoine de la Mothe Cadillac
Upon his arrival in America, La Mothe adopted his title after the town of Cadillac, Gironde in southwestern France. The city of Detroit became the world center of automobile production in the 20th century. William H. Murphy and Henry M. Leland founded the Cadillac auto company and paid homage to him by using his name for their company and his armorial bearings as its logo in 1902. Various places bear his name in America, in particular Cadillac Mountain in Maine and the town of Cadillac, Michigan.
Belle Isle Park (Michigan)
One night in 1908, Byron Carter of Cartercar stopped to help a stranded motorist on Belle Isle. When he cranked her Cadillac, it kicked back and broke his jaw. Complications from the injury resulted in pneumonia and he died. The incident motivated Henry Leland, founder of Cadillac Motors, to state that "The Cadillac car will kill no more men if we can help it". He hired Charles Kettering, who established Delco and developed the electric self-starter. This soon became standard on all automobiles.
