Abstract

It seems that many people contributed to the invention of the motion picture systems. In USA, it seems that Thomas A Edison (1847-1931) or his company did much of the practical work, initially proposing the Film principle. The cine-camera was achieved in a number of ways, mainly because the exposure can be a small portion of the interval between frames, BUT in the projection period, the film must be halted to give a good screen image for a large portion of the total interval. This is the point which Charles Francis Jenkins (1867-1934) says he saw first and proposed a "beater" to drive the film forward which became through Thomas Armat (1866-1948) the Geneva Cross Drive. Thus the final step was the combination of all three inventors with Edison and George Eastman (1854-1932) providing the continuous film and the Camera and the Projector, first demonstrated by Jenkins (early 1895) improved by Armat and made by Edison as the Vitascope.
