Eadweard James Muybridge (; 9 April 1830 – 8 May 1904) was a British photographer who spent much of his working life in California, and traveling in other parts of the United States. He is known for his pioneering work on animal locomotion in 1877 and 1878, which used multiple cameras to capture motion in stop-action photographs, and his zoopraxiscope, a device for projecting motion pictures that pre-dated the flexible perforated film strip used in cinematography.
