The early 20th century was called the Golden Age of Sport in America with such heroes as Babe Ruth and Jack Dempsey grabbing headlines. And alongside them on the front page were horses such as Man o' War, Colin, and Gallant Fox. The men who trained these champion racehorses became icons in their right, shaping the landscape of American horse racing during this time. In Masters of the Turf, well-known racing historian Edward L. Bowen takes an in-depth look at the lives of this elite group of trainers, including the legendary Sunny Jim Fitzsimmons, who trained two Triple Crown winners in the 1930s among a host of other champions for the powerful Belair Stud and Wheatley Stable; the father-son team of Ben and Jimmy Jones, who helped Calumet Farm dominate racing in the 1940s; and turn-of-the-century masters James Rowe and Sam Hildreth.
