Muybridge made his most important photographic studies of motion from 1884 to 1887 under the auspices of the University of Pennsylvania. These consisted of photographs of various activities of human figures, clothed and naked, which were to form a visual compendium of human movements for the use of artists and scientists.
Horse in Motion, Eadweard Muybridge, ca. 1886. Photography collection, Harry Ransom Center. It may come as a surprise in the twenty-first century to discover that in the 1880s, details of how objects move were unknown. The human eye, unaided, cannot resolve the details of fast motion. Eadweard Muybridge and his experiments with motion photography, such as this series of pictures of a horse's gait helped solve this mystery.
