British-born U.S. film director and producer who introduced animation and other important film techniques that helped shape and stimulate the development of cinematic art.

While interviewing Thomas A. Edison in 1895, Blackton's interest in films was so aroused that in the following year he and Albert E. Smith established Vitagraph; in 1899 they were joined by William T. Rock. Their first film, The Burglar on the Roof (1897), was followed by a long series of film successes that made Blackton a millionaire. He left Vitagraph for a while but returned to work for the company until it was sold in 1926 to Warner Brothers.

Blackton's motion-picture adaptations of Shakespeare's dramas were the first such produced in the United States. Many other of his films were centred on such well-known characters as Sherlock Holmes, Oliver Twist, Salome, Richelieu, Moses, and Saul and David. After losing his fortune in the economic depression of 1929, Blackton supported himself by exhibiting his old films at sideshows.
