Étienne-Jules Marey was born 5 March 1830 in Beaune, France. He was first and foremost a scientist, who was interested in animals, particularly birds, and their movement. However he is also known for his contributions to the photographic and cinematic fields and coined the term “Chronophotography.” Marey created many different machines for scientific use, including the portable sphygmograph, which measured blood pressure, and the photographic gun which took 12 frames per second on the same negative. This allowed him to study movement of animals and humans, which is known as locomotion.
The famous photos by Eadweard Muybridge that were taken of a galloping horse were taken after the artist visited Marey’s studio and was evidently inspired by Marey’s work. Marey published several books including Le Vol des Oiseaux (1890) and Le Mouvement (1894). He was also known for making movies that had 60 frames per second and of excellent image quality for the time period. These films had an impact on the emerging field of cinematography.
