Carl A. Roles
Usually known as Carl Roles, he was sometimes referred to by the nickname, "Slim." A Thoroughbred trainer and owner, he trained for prominent stable owners such as Ada L. Rice of Chicago and Hollywood film studio boss, Louis B. Mayer. In the 1930s he met with considerable success as the trainer of Time Supply for owner Frank A. Carreaud. The colt won a number of important races including the Massachusetts Handicap, San Antonio Handicap, San Vicente Handicap, and the Narragansett Special. However, Roles is best known as the trainer of Terrang whose race conditioning he took over in January 1957 after the horse was purchased by his clients, Roland Bond and Lawrence S. Pollock. In the summer of 1966, the owner of Desert Trial, Muriel Vanderbilt Adams, sent her horse west to trainer Carl Roles where he saddled him to a number of important stakes including back-to-back editions of the Ramona Handicap.
Daughter, Barbara Roles, won the 1958 United States Junior Women's Figure Skating Championship and in 1962, the Senior Women's Championship. She was also the Bronze medallist in the 1960 Winter Olympics. 
Carl Roles died at age sixty-six in 1970. At the time of his death, he was living in Pasadena, California.
