Thomas Edwin Mix (born Thomas Hezikiah Mix; January 6 1880 - October 12 1940) was an American film actor and the star of many early Western movies. He made a reported 336 films between 1910 and 1935, all but 9 of which were silent features. He was Hollywood’s first Western megastar and is noted as having defined the genre for all cowboy actors who followed.

The son of a lumberman, Tom Mix joined the army as a young man and was an artillery sergeant during the Philippine campaign from 1898 to 1901, though he never saw action. About 1903 he was drum major with the Oklahoma Cavalry Band, playing in the St. Louis World's Fair. In 1904 he was a bartender and sheriff-marshal in Dewey, Oklahoma. He was in a series of Wild West shows, such as The Miller bros. Wild West Show from 1906-1909; the Widerman show in Amarillo, Texas; with wife Olive Mix in Seattle's Alaska-Yukon-Pacific Exposition; and Will A. Dickey's Circle D Ranch. The latter supplied Selig Pictures with cowboys and Indians for movies and, in 1910, Mix was hired by Selig to provide and handle horses. His first movie was Ranch Life in the Great Southwest (1910). He continued with Selig until 1917, writing and directing as well as acting. He was signed by Fox Films in 1917 and stayed with them until 1928, averaging five or so films a year. In addition to Mix's riding and shooting skills, the films also showcased the talents of his amazing horse, Tony the Horse. Sound was not favorable to Mix, and after making a handful of pictures during the sound era he left the film industry, touring with the Sells Floto Circus in 1930 and 1931 and the Tom Mix Circus from 1936 to 1938. He died in an auto accident in 1940. Tom Mix developed a comical style, emphasized fast action thrills to a greater extent than had been common in earlier westerns, and did his own stunts. He was king of the cowboys during the 1920s and remained popular on radio and in comic books for more than a decade after his death.
