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.
Henry Ford Company
Cadillac's first car was completed on October 17, 1902, the 10 horsepower (7 kW) Cadillac. Based on Henry Ford's design (except for the engine, designed by Leland & Faulconer), it was practically identical to the 1903 Ford Model A.
