Photograph. After emigrating to America in 1852, Eadweard James Muybridge (1830- 1904) became a profesional photographer and was eventually appointed chief photographer for the United States government. In 1877, he used a series of still photographs to show that a trotting horse at times has all its feet off the ground, and in 1880 he devised the zoopraxiscope, a precursor of cinematography.
