Who is the man in the picture?

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 between 1909 and 1935. Mix appeared in 291 films, all but nine of which were silent movies. He was Hollywood's first Western star and helped define the genre as it emerged in the early days of the cinema.

He began his film career as a supporting cast member with the Selig Polyscope Company. His first appearance was in a short film, "The Cowboy Millionaire", released on October 21, 1909. In 1910, he appeared as himself in a short documentary film, "Ranch Life in the Great Southwest", in which he displayed his skills as a cattle wrangler. Shot at the Selig studio in the Edendale district of Los Angeles (now known as Silver Lake), the film was a success, and Mix became an early motion picture star and performed in more than 100 films for Selig, many of which were filmed in Las Vegas, New Mexico.

While with Selig he co-starred in several films with Victoria Forde, and they fell in love. He divorced Olive Stokes in 1917. By then, Selig Polyscope had encountered severe financial difficulties, and Mix and Forde both subsequently signed with Fox Film Corporation, which had leased the Edendale studio. They married in 1918 and had a daughter, Thomasina (Tommie) Mix, in 1922.
