There is an obit for Thompson in today's WSJ.
In it I learned that THOR is a concatenation of the first two letters of the names of Thompson and Orthwein who purchased Airstream years ago.
Peter Orthwein and the Orthwein family is famous in polo circles. He endowed a chair for the coach of the polo team at Cornell where he was a renowned player in his own right. The family is also descended from the Busch family of St. Louis, Mo.
With this pedigree, perhaps Budweiser should be the semi-official beer of Airstream.
