Étienne-Jules Marey
From Wikipedia, the free encyclopedia
Étienne-Jules Marey (March 5, 1830 – May 15, 1904) was a French scientist and chronophotographer.
Born born in Beaune, his work was significant to the development of cardiology, physical instrumentation, aviation, cinematography and the science of labor photography. He is widely considered to be a pioneer of photography and an influential pioneer of the history of cinema.
He started by studying how blood moves in the body. Then he shifted to analyzing heart beats, respiration, muscles (myography), and how a body as a whole moves. To aid his studies he developed many instruments for precise measurements. For example, he was successfully selling an instrument called Sphygmographe to measure the pulse. In 1869 Marey constructed a very delicate artificial insect to demonstrate how an insect flies and the figure-8 shape it produced during its movement. Then he became fascinated by movements of air and started to study bigger flying animals, like birds. He adopted and further developed animated photography into a separate field of chronophotography in the 1880s. The revolution was to record several phases of movement in one surface. In 1890 he published a substantial volume entitled Le Vol des Oiseaux (“The Flight of Birds”) richly illustrated with photographs, drawings, and diagrams. He also created stunningly precise sculptures of various flying birds.
Marey studied other animals too. He published La Machine Animale in 1873 (translated as "Animal Mechanism"). English photographer Eadweard Muybridge held "Photographic Investigation" in Palo Alto, California trying to prove that Marey was right when he wrote that a galloping horse for a brief moment had all four hooves off the ground. Muybridge published his photos in 1879 and got some public attention.
Marey hoped to merge anatomy and physiology. To better understand his chronophotographic images, he compared them with images of the anatomy, skeleton, joints, and muscles of the same species. Marey produced a series of drawings showing a horse trotting and galloping, first in the flesh and then as a skeleton.
He studied and took chronophotographic pictures of horses, birds, dogs, sheep, donkeys, elephants, fish, microscopic creatures, molluscs, insects, reptiles, etc. Some call it Marey’s "animated zoo". Marey also conducted the famous study about cats landing always on their feet. He conducted very similar studies with a chicken and a dog and found that they could do almost the same. Marey also studied human locomotion. He published another book Le Mouvement in 1894.
Marey also made movies. They were at a high speed (60 images per second) and of excellent image quality: in slow-motion cinematography, he had come close to perfection. His research on how to capture and display moving images helped the emerging cinematography.
Towards the end of his life he returned to movement of quite abstract forms, like a falling ball. His last great work was the observation and photography of smoke trails. In 1901 he was able to build a smoke machine with 58 smoke trails. It became one of the first aerodynamic wind tunnels.
