4. In 1872, Leland Stanford, a businessman and race-horse owner, hired Muybridge for some photographic studies. He had taken a position on a popularly debated question of the day — whether all four feet of a horse were off the ground at the same time while trotting.
In 1872, Muybridge settled Stanford's question with a single photographic negative showing his Standardbred trotting horse Occident airborne at the trot.
Stanford also wanted a study of the horse at a gallop. Muybridge planned to take a series of photos on 15 June He placed numerous large glass-plate cameras in a line along the edge of the track; the shutter of each was triggered by a thread as the horse passed.
