James Edward "Sunny Jim" Fitzsimmons (July 23, 1874 – March 11, 1966) was a thoroughbred racehorse trainer. Born in Sheepshead Bay, Brooklyn in 1874, Fitzsimmons began his career in 1885 working at a racetrack as a stable boy. After nearly ten less-than-successful years as a thoroughbred jockey, he became too heavy for that job and took up the training of horses. He went on to have one of the most successful careers in racing history that spanned seventy years from 1894–1963 and produced 2,275 race wins. Selected other major stakes race wins:
