The Mutoscope was an early motion picture device, invented by W.K.L. Dickson and Herman Casler[1] and later patented by Herman Casler on November 21, 1894.[2] Like Thomas Edison's Kinetoscope, it did not project on a screen and provided viewing to only one person at a time. Cheaper and simpler than the Kinetoscope, the system, marketed by the American Mutoscope Company (later the American Mutoscope and Biograph Company), quickly dominated the coin-in-the-slot peep-show business.
