Marey was familiar in a general way with all these developments and ideas, but he was essentially a scientist and not a photographer. Motion picture photography to him was just a good way of learning more about living movement. About 1870 he had made studies of movements in other ways in addition to primitive photographs and drawings made from such photographs. The results of these studies were known all over the world and had a direct influence on the photographers who first successfully took successive pictures of animals in motion. These photographers were Eadweard Muybridge and John D. Isaacs. Eadweard Muybridge (1830–1904), or Edward James Muggeridge, as he was originally named, was born in England, at Kingston-on-Thames. As a young man he was an adventurer who called photography his profession. He made a number of trips back and forth between the United States and England. He was seriously injured in a run-away stage coach accident in July of 1860, in Arkansas, and later obtained several thousand dollars in damages from the Southern Overland Stage Company. Returning to the United States after a visit in England, following the accident, Muybridge received an assignment to photograph, for the United States Coast and Geodetic Survey, the new territory of Alaska, purchased by the United States in 1867. After this assignment he settled in San Francisco. In 1872 Governor Leland Stanford of California made a $25,000 bet in connection with a dispute as to whether or not all the legs of a horse running at a full gallop are off the ground simultaneously. The eye was not quick enough to find the answer. Horsemen had never been completely satisfied with the drawings and pictures made by artists of horses in motion. Sanford, as Terry Ramsaye describes in his history of the motion picture, _A Million and One Nights_, in 1872 sent for the photographer Muybridge and had him go to the Sacramento race track to get photographic proof in order to settle the dispute. Over a period of years Stanford spent considerably more than the $25,000 wager on the photographic experiments. And out of the experiments grew the legend that Muybridge had invented “motion pictures.” About 1870 Marey had established the movement of the legs of a horse in a gallop through his physiological investigations. But at that time he had no photographic proof of his theory. Years later Muybridge said that Stanford obtained his basic ideas for photographs to win the bet from the writings of Marey. Muybridge might have been successful in his early experiments if it had not been for an interruption which was of about five years’ duration. He had domestic troubles of a nature that ended in violence. In October 1874, he shot and killed Major Harry Larkyn who had eloped with his wife. After a sensational trial in which the defense was able to succeed in putting the jurors mentally in Muybridge’s place, he was acquitted on February 5, 1875, at the courthouse in Napa, California.
