David Wark Griffith (January 22, 1875 – July 23, 1948) was an American film director. Considered one of the most influential figures in the history of the motion picture, he pioneered many aspects of film editing. Griffith is known to modern audiences primarily for directing the film The Birth of a Nation (1915). One of the most financially successful films of all time. Together with Charlie Chaplin, Mary Pickford, and Douglas Fairbanks, Griffith founded the studio United Artists in 1919 with the goal of enabling actors and directors to make films on their own terms as opposed to those of commercial studios.
