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.
LaSalle (automobile)
LaSalle was an American brand of luxury automobiles manufactured and marketed by General Motors' Cadillac division from 1927 through 1940. Alfred P. Sloan developed the concept for LaSalle and certain other General Motors' marques in order to fill pricing gaps he perceived in the General Motors product portfolio. Sloan created LaSalle as a companion marque for Cadillac. LaSalle automobiles were manufactured by Cadillac, but were priced lower than Cadillac-branded automobiles and were marketed as the second-most prestigious marque in the General Motors portfolio.
