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.
Muybridge's pictures, published widely in the late 1800s, were often cut into strips and used in a Praxinoscope, a descendant of the zoetrope device, invented by Charles Emile Reynaud in 1877. The Praxinoscope was the first 'movie machine' that could project a series of images onto a screen.
