Étienne-Jules Marey: The Chronophotographic Gun

By Infinite Creation · Profile

Historical photograph of Étienne-Jules Marey.

At a Glance

Étienne-Jules Marey (1830-1904) built the chronophotographic gun in 1882, a camera shaped like a rifle that recorded twelve exposures a second onto a single rotating plate. Unlike Muybridge's battery of separate cameras, Marey's device captured a sequence from one viewpoint through one lens, which is what a motion picture camera does.

Career

The problem as it stood

Muybridge's method needed a bank of cameras along a track, each with its own viewpoint, so the sequence shows the subject from progressively different angles. For studying the mechanics of movement that is a defect: the changing viewpoint contaminates the measurement.

What he actually did

Marey built a device with a single lens and a rotating shutter and plate, capable of twelve exposures per second from one fixed viewpoint. He later moved to paper roll film, recording sequences on a continuous strip.

How it worked

A clockwork mechanism advanced a circular photographic plate behind a rotating slotted disc, so successive exposures fell on successive sectors. One lens, one viewpoint, many instants: the architecture of every film camera since. His move to flexible roll film anticipated the format the industry would settle on.

What it made possible

Marey's work fed directly into the development of cine cameras, and his analytical approach created the field of movement study that runs through ergonomics, sports science and eventually motion capture. Georges Demenÿ, his assistant, went on to his own projection work.

What happened to him

Marey remained a scientist rather than a showman, publishing extensively on animal and human locomotion, cardiology and instrumentation. He died in 1904, the same year as Muybridge.

Where the credit landed

Marey is respected but comparatively under-read in film history, partly because he was not trying to make films: he wanted graphs of movement, and the pictures were instruments. The single-lens, single-viewpoint, sequential-exposure architecture he built is nonetheless closer to a movie camera than anything Muybridge made: an illustration of how the person pursuing a different goal often builds the more consequential machine.

Known For

Muybridge used many cameras, Marey used one. That is why Marey's is the ancestor of the movie camera.
He was measuring movement, not entertaining an audience.
His shift to paper roll film anticipated the industry's format.

Knowledge Base

What You'll Learn

The distinction between Muybridge and Marey is the distinction between a photo finish and a film camera.

Why one viewpoint matters

With a bank of cameras, each frame is taken from a slightly different position, so the subject appears to shift against the background as the sequence plays. That is fine for demonstrating a gait and useless for measuring one. A single fixed lens removes the variable, and it is also what makes the resulting sequence read as continuous movement rather than as a tracking shot.

Where This Fits

Marey's gun captured motion as a sequence, an early link in the chain followed in A History of Broadcast Technology.

FAQ

Q: What is chronophotography?
A: Photographing successive phases of a movement in order to analyse it, recording time as a sequence of images. Marey's chronophotographic gun captured twelve such exposures per second on one plate through one lens.

Q: Was Marey trying to invent cinema?
A: No. He was a physiologist studying the mechanics of movement, and the photographs were measurements. The architecture he arrived at nevertheless became that of the motion picture camera.

Vocabulary

Chronophotography. Recording successive phases of a movement as a series of images, in order to study motion rather than to reproduce it. The direct ancestor of both cinematography and motion capture.

Frame rate. How many images are captured each second. Determines how finely a movement is sampled, and whether the reconstruction shows smooth motion or a series of separate positions.

Motion study. The analysis of how a body or a machine moves, broken into stages. Photography made it possible to see phases of movement too fast for the eye to separate.

Exposure. The period during which light is allowed to reach the recording surface. Short exposures freeze a phase of movement, and long ones blur it, which is the fundamental trade in capturing motion.

Marey's own article on the apparatus was read, and it matches the description above. Checked 20 August 2026.

Étienne-Jules Marey, Le Fusil photographique. La Nature, revue des sciences, année 10, premier semestre 1882, pages 326 to 330, transcribed by Wikisource. Marey describes the mechanism himself and gives the rate as twelve exposures per second at one seven hundred and twentieth of a second each, which is the figure used above. He notes doubling the shutter speed later to study wing movement.
