Frederick S. Armitage (June 19, 1874 in Seneca Falls, New York – January 3, 1933 in Ecorse, Michigan) was an early American motion picture cinematographer and director, working primarily for the American Mutoscope and Biograph Company. Often identified as "F.S. Armitage" in AM&B paperwork, Armitage had a hand in creating more than 400 often very short subjects for AM&B in the days where its films were made as much for the hand-crank operated Mutoscope device as for projection. Several of Armitage's subjects stand out from the company's regular routine of actualities and comic skits in their innovative use of camerawork, superimpositions, time-lapse photography and other effects then new to the art of film-making.
