Cadillac, the brand.
I often wondered about its genesis, and now I think I know.
From Wiki, regarding that town on the Garonne:
"The name of the commune was adopted by Antoine Laumet de La Mothe, sieur de Cadillac, the founder of Detroit and Governor of Louisiana, on his arrival to what is now the United States. The Cadillac division of General Motors, and Cadillac, Michigan are named after him."
At the same time, my thoughts for the people of West, Texas. Maybe this disaster will cause changes to town/factory planning laws, depending on the nature of products being employed in manufacture. Let's hope there were no intended causes to this latest horror.
