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.

Founded by 50 women in 1888, the hospital was transitioning from convalescent treatment to modern insurance-based medical care in the early 1910s. A new hospital building was needed, and the all-women board sought outside assistance for the first time. They first met with Clarence Black, President of Cadillac, in 1914 and asked him to form a board and take over. Black made the hospital's plight known to his friends and all four, over the next year or two, joined the board and began funding the hospital's growth in significant ways.
