In 1878 and 1879 at the Palo Alto Farm, now the site of Stanford University, an extensive photographic experiment portraying the attitudes of men and animals in motion was conceived and executed under the direction and patronage of Leland Stanford. Consecutive instantaneous exposures were provided by a battery of twenty four cameras fitted with electro shutters. Eadweard J Muybridge carried out the investigation and showed that the photographs could be combined in projection to give the true appearance of motion. John D Isaacs advanced the research by devising electrical equipment, and J D B Stillman analysed the photographs relating to the locomotion of the horse.
