Overview
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.

Steps
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.
Pro Tips
- 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.

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
This guide covers one specific part of the history of media technology. The wider picture — how each link in the chain from capture through transmission to display was actually built, who built it, and why the credit so often landed somewhere else — is in A History of Broadcast Technology: The Chain From Capture to Screen, which frames the discipline as a whole and links out to the detailed guides underneath it, including this one.

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.
