William B. Finnegan (September 19, 1890 – October 18, 1970) was an American Thoroughbred horse racing trainer.
A native of New York City, Finnegan spent more than fifty years as a trainer primarily on the West Coast of the United States.
[1] During his career he conditioned horses for major stable owners such as Vera S. Bragg,[2] movie mogul Louis B. Mayer, Walter P. Chrysler Jr.,[3] Edward S. Moore's Circle M Ranch stable,[4] George A. Pope, Jr.'s El Peco Ranch,[5] and Neil S. McCarthy who would name one of his horses in his honor.
En route to being named American Champion Older Male Horse, Big Pebble's wins included the most important and richest race in Florida, the Widener Challenge Cup at Hialeah Park Race Track[9] and the prestigious Hollywood Gold Cup at California's Hollywood Park Racetrack.
[10] In October 1951, that year's Kentucky Derby winner Count Turf was sent to Bill Finnegan to race in California but met with little success.
