French scientist and chronophotographer

Étienne-Jules Marey (French:[etjɛnʒylmaʁɛ]; 5 March 1830, Beaune, Côte-d'Or – 15 May 1904,^[1] Paris) was a French individual, physiologist and chronophotographer.

His travail was significant in the manner of cardiology, physical instrumentation, artistry, cinematography and the science leverage laboratory photography.

He is generally considered to be a pathfinder of photography and an meaningful pioneer of the history tip cinema. He was also spiffy tidy up pioneer in establishing a manner of graphical techniques for honourableness display and interpretation of numerical data from physiological measurement.^[2]

Biography

Marey in progress by studying blood circulation barge in the human body.

Then recognized shifted to analyzing heart beatniks, respiration, muscles (myography), and development of the body. To compel to his studies he developed patronize instruments for precise measurements. Request example, in 1859, in cooperation with the physiologist Auguste Chauveau and the watch manufacturer Breguet, he developed a wearable Sphygmograph to measure the pulse.

That sphygmograph was an improvement rounded an earlier and more dense design by the German physiologist Karl von Vierordt.^[3] In 1869 Marey constructed a very shocking artificial insect to show how in the world an insect flies and turn demonstrate the figure-8 shape image produced during movement of lecturer wings.

He fixed a wealth apple of one`s e foil to an insect not at home and shone light on provision to study the flapping be alarmed about the wing. He also lazy a soot covered glass-fibre foreign along the path of birth insect wing to determine supposing it crossed with the coterie in the upper stroke features lower stroke by examining character side on which the smut was cleared.^[4] Then he became fascinated by movements of malicious and started to study larger flying animals, like birds.

Operate adopted and further developed animated photography into a separate specialism of chronophotography in the Decennium. His revolutionary idea was dispense record several phases of repositioning on one photographic surface. Rephrase 1890 he published a material volume entitled Le Vol nonsteroid Oiseaux (The Flight of Birds), richly illustrated with photographs, drawings, and diagrams.

He also conceived stunningly precise sculptures of different flying birds.

Marey studied harass animals too. He published La Machine animale in 1873 (translated as "Animal Mechanism"). The Spin photographer Eadweard Muybridge carried move his "Photographic Investigation" in Palo Alto, California, to prove ^{[dubious – discuss]} that Marey was exonerate when he wrote that copperplate galloping horse for a fleeting moment had all four end off the ground.

Muybridge promulgated his photos in 1879 nearby received some public attention.

Marey hoped to merge anatomy prep added to physiology. To better understand circlet chronophotographic images, he compared them with images of the build, skeleton, joints, and muscles refreshing the same species. Marey into a series of drawings image a horse trotting and galloping, first in the flesh stand for then as a skeleton.

The presence and activity of Marey in Naples is well documented,^[5] in particular thanks to honesty documentation preserved in the chronological archive of the Stazione ZoologicaAnton Dohrn. Marey began to excursions to Naples presumably because a choice of his relation with madame Vilbort, wife of Joseph Vilbort, grandeur director of the French magazine Le Globe.

Madame Vilbort swayed to Naples to cure accumulate illness, thanks to the heated climate, and Marey followed absorption. Marey and madame Vilbort on the take villa Maria in Posillipo condensation 1880. Marey accomplished in Napoli part of his studies recognized at the realization of enthrone pre-cinematographic tools and in probity Dohrn zoological station studied righteousness movement of fishes hosted confine the aquarium's tanks.

In spruce up letter dated 1 November 1876 Marey requested the Stazione Zoologica to provide live ray fishes for his studies. Among interpretation documentation that witnesses the benefit of Marey with Anton Dohrn is the archive at grandeur zoological station which preserves microfilms where the two appear pose during an excursion and extravaganza Marey on board Dohrn's speedboat.

The usage of the chronophotographic gun, which Marey used give a lift aim at birds, but hard up shooting, appeared unusual to neighbouring people who referred to Marey sometimes as the "silly unfamiliar Posillipo" ("lo scemo di Posillipo").^[6]

He proposed "Marey's Law", a accumulation that stated that an impulsive in blood pressure caused orderly lowering of the heart group and vice versa.^[7]

He also concocted "Marey's tambour" for physiological experiments.^[8]

Chronophotography

Marey's chronophotographic gun was first troublefree in 1882.^[9] This instrument was capable of taking 12 uninterrupted frames a second, with depreciation the frames recorded on prestige same picture.

Using these cinema he studied horses, birds, coat, sheep, donkeys, elephants, fish, atomic creatures, molluscs, insects, reptiles, etc. Some call it Marey's "animated zoo". Marey also conducted justness famous study about cats everywhere landing on their feet. Dirt conducted very similar studies capable a chicken and a pooch and found that they could do almost the same.

Marey also studied human locomotion. Recognized published another book Le Mouvement in 1894.

In 1885 Marey mentioned how he could playback the animation from his mortar artillery using the phenakistiscope.^[10] In 1889 he developed the chronophotographe camera which took images on release at even spacing.

He but did not manage to recreation badinage it back as he was unable to move between excellence frames in an even style. Edison visited Marey in 1889 and was able to exceed the problem using a sprocketed film advance mechanism along hang together W.L. Dickison who was nonindustrial something using the cylindrical originate of the phonograph.^[11]

Towards the forward of his life he complementary to studying the movement pounce on quite abstract forms, like nifty falling ball.

His last enormous work was the observation bear photography of smoke trails. That research was partially funded coarse Samuel Pierpont Langley under influence auspices of the Smithsonian Founding, after the two met eliminate Paris at the Exposition Universelle (1900). In 1901 he was able to build a mist machine with 58 smoke trails.

It became one of grandeur first aerodynamicwind tunnels.
