Arguably the greatest racing horse in American history; Man O' War was born in 1917, son of Fair Play and Mahubah. He was sold as a yearling at Saratoga for the ironically cheap price tag of $5,000, to Samuel Riddle. His jockey was Johnny Loftus; he only lost one race in his entire career, and that, most agree, was due to bad luck. His most celebrated victory was against the Canadian horse, Sir Barton, who happened to be the first winner of the Triple Crown.
