Then there was Clyde Van Dusen. Clyde Van Dusen was a Derby winner trained by Clyde Van Dusen. (Note to editor – NOT a typo! Do not correct!) Yep, in 1929, the winning horse had the same name as his trainer. The horse Clyde was so named because the human Clyde won a coin flip over naming rights with the horse’s owner, Herbert Bunbury. (Okay, actually Herbert Gardner.)
I don’t think I’d ever want a Derby winner named after me. I’d hate to suffer the fate of the human Clyde Van Dusen, whose Wikipedia entry is 15% shorter than that of the horse Clyde Van Dusen.
