Eadweard Muybridge was an English Landscape photographer who while in America in 1872 was asked by American Horse Breeder to settle an arguement about Horse movement. Using a bank of 12 cameras Muybridge produced series of photos that showed the stages in a movement.
Muybridges series of photos freezing movement were meant as an means of analysing movement, though he quickly realised the prints could be fixed in a zootrope to create a simulated moving image. By 1878-1880 technogy enabled the beginning of moving film,
