Why did the lumière brothers invented the cinématographe

This community of work is coupled with a perfect fraternal understanding. The two brothers, who had married two sisters, lived in symmetrical apartments in the same villa. It is the sale of these plates that made the fortune of the family. From the first year, they made us nearly , francs. Each of the ten reels projected during this session lasts about fifty seconds.

Their success was the result of an uninterrupted series of inventions. In , John Carbutt invented a flexible cellulose nitrate strip, which George Eastman marketed in the United States in From May to the end of , the Americans Thomas Edison, the inventor of the phonograph, and especially his assistant and first film director, William Kennedy Laurie Dickson, produced and shot some films, recorded with the Kinetograph camera and viewed individually by the public with the help of the kinetoscope viewing through a magnifying glass.

They created not only the first movie studio, the Black Maria, but also the Kinetoscope Parlors, slot machines, which prefigured not so much the movie theaters as the arcade. For Antoine, there was no doubt: the moving image was a future market for the family, aimed at its usual clientele, the wealthy amateurs, provided that the miracle of the moving photographic image was combined with the magic of projection on a large screen.

He failed and it was Louis who took over. Like Edison, he adopted the 35 mm format, but in order not to infringe on the film with eight rectangular perforations around each photogram, patented by the American inventor and industrialist, he chose a formula with two round perforations per photogram later abandoned. Louis' invention was in fact a reworking of a pre-existing mechanical process, the principle of which he adapted to the intermittent movement of the film, necessary for the exposure of the images one after the other, but the emergence of this idea remained in the minds of the two brothers bathed in a miraculous perfume: Louis would have been ill and feverish, and, during an insomnia, he would have imagined giving "to a claw-holder frame an alternating movement, analogous as to operation to that of the crowbar of a sewing machine, the claws sinking at the top of the stroke, into perforations made on the edges of the film that was to carry the image, to drive the latter and, withdrawing at the bottom of this stroke, leaving the film immobile while the drive system rises.

It was a revelation. The kinetograph also used intermittent movement of the film, also through a pre-existing mechanism: an electric ratchet cam attached to a toothed drum driving the film. Like the kinetograph, a rotating shutter prevents light from reaching the light-sensitive layer when the film moves one step. The Edison-Dickson camera is explicitly cited as a pre-existing reference.
