Tom Mix (1880 - 1940) was arguably the greatest cowboy superstar of silent film era--he certainly had a flashier wardrobe. He made over 300 films between 1910 and 1935. His horse was also a celebrity, and was billed as "Tony the Wonder Horse." Mix did most of his own stunts, and suffered many injuries as a result.
