Harry Clayton Richards (March 24, 1908 - January, 1980) was an American Thoroughbred horse racing jockey and the first president of the Jockeys' Guild. Hall of Fame jockey Eddie Arcaro said Richards: "was strong in character and who maintained a steady belief in our organization [Jockeys' Guild]. Incidentally, he was one of the greatest riders of my time, the first switch-hitter in our business and the one from whom I copied switch-hitting.
Born in Brooklyn, New York, Richards began riding professionally in 1924. During his career he rode for prominent owners such as Walter Jeffords, George Widener and William duPont, Jr. In 1937 he rode duPont's colt Rosemont to victory in the Santa Anita Handicap, defeating Seabiscuit, a scene used in the 2003 motion picture Seabiscuit in which Richards was portrayed by jockey Corey Black.
In 1936, Harry Richards rode Jeome Louchheim's colt Pompoon to victory in the richest and most prestigious race for juveniles, the Futurity Stakes at Belmont Park. Pompoon was voted American Champion Two-Year-Old Colt honors. In 1937, he rode Pompoon to a second-place finish in the Kentucky Derby to War Admiral, finishing a length and a half back.
