About Étienne-Jules Marey
Étienne-Jules Marey (French: [etjɛn ʒyl maʁɛ]; 5 March 1830, Beaune, Côte-d'Or – 15 May 1904, Paris) was a French scientist, physiologist, and chronophotographer. His work was significant in the development of cardiology, physical instrumentation, aviation, cinematography, and the science of laboratory photography. He is widely considered to be a pioneer of photography and an influential pioneer of the history of cinema. He was also a pioneer in establishing a variety of graphical techniques for the display and interpretation of quantitative data from physiological measurement. Marey produced a series of drawings showing a horse trotting and galloping, first in the flesh and then as a skeleton. He also invented "Marey's tambour" for physiological experiments. His revolutionary idea was to record several phases of movement on one photographic surface. He also created stunningly precise sculptures of various flying birds.
