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
With the help of C. Harold Wills, Ford designed, built, and successfully raced a 26-horsepower automobile in October 1901. With this success, Murphy and other stockholders in the Detroit Automobile Company formed the Henry Ford Company on November 30, 1901, with Ford as chief engineer. In 1902, Murphy brought in Henry M. Leland as a consultant; Ford, in response, left the company bearing his name. With Ford gone, Murphy renamed the company the Cadillac Automobile Company.
