In 1872, Eadweard Muybridge, a British-born photographer, was hired by Leland Stanford (who later founded the university), to settle a question (some people say a $25,000 bet) whether there was a point in a horse’s full gallop where all four hooves were off the ground.
Muybridge arranged 12 cameras alongside a race track and attached a string to the camera switches across the track. When the horse ran through the string, it triggered the shot. The series of photographs showed that indeed, all four hooves leave the ground when the horse is in full gallop.
