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.
Cadillac
In 1953, the "Autronic Eye" was introduced. This feature would automatically dim high-beam headlamps for the safety of oncoming motorists. In 1957, Cadillac attempted to move further upmarket, creating the hand-built Series 70 Eldorado Brougham. It featured self-levelling suspension, "memory seat" function, and an all-transistor signal-seeking car radio that was produced by GM's Delco Radio and which was available as standard equipment for the 1957 Eldorado Brougham models. While the car showed Cadillac's technological prowess, it only sold 904 units.
