Whom or what was the Borg-Warner trophy named after?

Question

Which trophy, damaged by Benjamin Peri Nathan with a sledgehammer in March 1997, was restored to its original condition, free of charge, by London silversmiths Garrard & Co., who had made it in 1848?

Answer 1

Borg-Warner Automotive Company
The Borg-Warner company commissioned the trophy for presentation in 1936 to the winner of the 24th annual 500-mile race which was then part of the AAA Car Championship series. With some refurbishment it is still the trophy for the winner of the (now) Indianapolis 500.
