“Like his contemporary Eadweard Muybridge, Marey, a physiologist, was interested in the science of human movement. By 1882, he had developed a single camera method that he called chronophotography, which allowed him to make images of human and animal movement. His camera was the forerunner of the motion picture camera.
Marey’s chronophotographs were some of the first images to illustrate the exact process of body movement.”
