On 11 August 1877, the "Daily Alta" newspaper announced a project by Eadward Muybridge and Leland Stanford to produce sequences of photographs of a running horse with 12 stereoscopic cameras. Muybridge had much experience with stereo photography and had already made instantaneous pictures of Stanford's horse Occident running at full speed. He eventually managed to shoot the proposed sequences of running horses in June 1878, with stereoscopic cameras. In 1898, Muybridge claimed that he had soon after placed the pictures in two synchronized zoetropes and placed mirrors as in Wheatstone's stereoscope resulting in "a very satisfactory reproduction of an apparently solid miniature horse trotting, and of another galloping".
