Additional Description

Container Summary

11 photos of the translation of Louis DuCos' patent on a camera in 1864, used as evidence by Thomas Armat, probably in Armat Motion Picture Company v. Edison Manufacturing Company. In 1864 DuCos invented a concept for a motion picture camera, but he was never able to create the device. He took out a patent on his idea. In the 1890's, C. Francis Jenkins "rediscovered" DuCos' patent and attempted to create the camera. Jenkins' device was flawed, but in 1895 when he met Thomas Armat, he told Armat that his version of DuCos' camera was operable.
