Photograph showing phases of movement of a man jumping a hurdle, made by Étienne-Jules Marey, c 1892.
French doctor Étienne-Jules Marey saw the medical potential of high-speed photography. He invented a ‘photographic gun’ to capture a range of humans, animals and birds in movement. He later developed his own camera to photograph subjects at the Station Physiologique in Paris, a centre for physical and mental recuperation. His process fixed a series of images on a single plate, such as this jumping man, from which he could take exact measurements.
