The Mutoscope is an early motion picture device, invented by W. K. L. Dickson and Herman Casler[1] and granted U.S. patent 549309A to Herman Casler on November 5, 1895.[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.
