For a story about one of the things that made Cadillac "The Cadillac" of
automobiles, see http://www.uh.edu/engines/epi133.htm.

Caddilac, incidentally, was named after Le Sieur Antoine de la Mothe
Cadillac, the Frenchman who in 1701 built a stockade, trading post, and
settlement called Ville d’Etroit, now known as Detroit. See

But to avoid an international incident, it should be stated the ordinary
engineering educated Englishman quite understands the meaning of "Cadillac"
although he may not have the foggiest idea of where the name came from. Was
it named after a red-indian tribe such as Cincinatti or Detroit?
