Discovery (1931–1958) was a champion American Thoroughbred racehorse. In a racing career which lasted from 1933 to 1936 he ran sixty-three times and won twenty-seven races. One of the leading American three-year-olds of his generation in 1934, he became a dominant performer in the next two seasons. The National Museum of Racing and Hall of Fame said that he was: "...considered one of the greatest horses of the 20th century."[1]
