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.
McLaughlin Motor Car Showroom
The building remained continuously occupied by car dealerships for eighty-two years. In 1955, it was opened as a Cadillac dealership by Harry Addison, and was known as Addison on Bay. It later became Canada's largest Cadillac dealership, and by the 1980s was operated by former Member of Parliament John Hollings Addison. Despite its long history, the dealership was closed as part of a reorganization and consolidation of the car dealership industry in Canada.
