Carroll M. Bierman (October 22, 1918 – March 22, 1970) was an American Thoroughbred horse racingjockey born in Centralia, Illinois. In 1940, he won the Kentucky Derby on Gallahadion in an upset over heavily favored Bimelech. That Derby ride is considered one of the best by a jockey in America's great race. Gallahadion paid $72.40 on a $2 bet for winning the "Run for the Roses" in the colors of Ethel V. Mars, of the Mars Candy fortune. He rode in the Kentucky Derby four times and finished 3rd, 4th, and 6th in the other three. He also won the 1939 Santa Anita Derby aboard the filly Ciencia.
Bierman's burgeoning career was interrupted by service with the United States Navy during World War II. Discharged in May 1945, he returned to racing after a fitness regimen designed to shed the weight he had gained.
