Seabiscuit (May 23, 1933 to May 17, 1947), foaled in Lexington, Kentucky, on May 23, 1933, from the mare Swing On and sire Hard Tack, a son of Man o' War, was a champion thoroughbred racehorse in the United States that became the top money-winning racehorse up to the 1940s. He beat the 1937 Triple Crown winner, War Admiral, by four lengths in a two-horse special at Pimlico and was voted American Horse of the Year for 1938. Seabiscuit has been immortalized in books and films, including the Shirley Temple film, The Story of Seabiscuit (1949); the book, Seabiscuit: An American Legend (1999) by Laura Hillenbrand, along with the film adaptation of Hillenbrand's book, Seabiscuit (2003), that was nominated for the Academy Award for Best Picture.
