American Bison Cantering by Eadweard Muybridge, Waugsberg [Public domain], via Wikimedia Commons

Eadweard Muybridge lived an interesting life (1830 – 1940)  as a photographer and is especially famous for a series of photographs of a horse running. He was commissioned by Leland Stanford to photograph his horse, Sallie Gardiner, in order to resolve the question of whether all four legs of a horse were off the ground at one time when trotting. Anyway, the Wikipedia article about his life has more examples of his photography.
