The Mitchell Camera Corporation was founded in 1919 by Americans Henry Boger and George Alfred Mitchell as the National Motion Picture Repair Co. Their first camera was designed and patented by John E. Leonard in 1917, from 1920 on known as the Mitchell Standard. Features included a planetary gear-driven variable shutter and a unique rack-over design.
Mitchell supplied camera movements for Technicolor's Three-Strip camera, and movements for others' 65mm and VistaVision conversions before later making complete 65mm and VistaVision cameras.
Mitchell also made a pin-registered background plate projector with a carbon arc lamphouse which was synchronized with the film camera. One of the first MPRPPs was used in Gone with the Wind. Two- and three-headed background projectors evolved for VistaVision effects.
George Mitchell received an Academy Honorary Award in 1952. The Mitchell Camera Company received an Academy Award for Technical Achievement in 1939, 1966 and 1968.
