Hobart Bosworth (1867-1943) was born in Marietta, Ohio. Bosworth was a pioneer actor/director/producer/writer, who appeared in at least 275 films between 1908 and 1942. In his youth he ran away from home and went to sea as a cabin boy and later a sailor. At 18 he appeared as an actor on the stage. A serious bout with tuberculosis ruined his voice for the stage and required that he live in a relatively warm and dry climate, so he transitioned to a career in film at the Selig Polyscope Company, where he appeared in approximately 128 films between 1908 and 1913. He formed Hobart Bosworth Productions Company in 1913, for which he made films until 1915. The company gained renown for several films based on the books of Jack London, whose works Bosworth greatly admired. After 1915 Bosworth appeared in some 120 films as an actor, working mainly in supporting roles but occasionally as the lead, for such companies as Paramount, Universal, Metro-Goldwyn-Mayer, 20th Century-Fox, and Columbia, as well as many of the smaller studios whose output was primarily "B" pictures, until his final film appearance in SIN TOWN (1942). His credits include THE COUNT OF MONTE CRISTO (1908), THE WONDERFUL WIZARD OF OZ (1910), THE COMING OF COLUMBUS (1912), THE SEA WOLF (1913), AN ODYSSEY OF THE NORTH (1914), OLIVER TWIST (1916), THE BIG PARADE (1925), ANNIE LAURIE (1927), DU BARRY, WOMAN OF PASSION (1930), DIRIGIBLE (1931), LADY FOR A DAY (1933), and THE CRUSADES (1935).
