Peter Fuller, auto dealer, racehorse owner, and boxer; at 89
Peter Fuller was a Harvard graduate and a Golden Gloves boxer. He ran his family’s successful Cadillac business and, in his 50s, sparred with Muhammad Ali for charity. And he entered the history books when his horse, Dancer’s Image, dramatically won the Kentucky Derby in 1968, only to be disqualified afterward. “He was sort of a character out of Hemingway,” Richard Johnson, curator of The Sports Museum in Boston, said of Mr. Fuller.
