Dorothy Karolyn Granger was an American actress best known for her roles in short subject comedies in Hollywood.

Educational Pictures, also known as Educational Film Exchanges, Inc. or Educational Films Corporation of America, was an American film production and film distribution company founded in 1916 by Earle Hammons (1882–1962). Educational primarily distributed short subjects; it is best known for its series of comedies starring Buster Keaton (1934–37) and the earliest screen appearances of Shirley Temple (1932–34). The company ceased production in 1938, and finally closed in 1940 when its film library was sold at auction.
