The Lumière Cinématographe was widely hailed. In his usual generous manner, Marey praised the accomplishment even though he must have been disappointed that others had achieved what he had long been seeking. The Cinématographe was shipped to England and the United States at an early date. In New York it was exhibited first in June, 1896, at Keith’s 14th Street Theatre, on Union Square. In both countries it was a stimulus to imitators. It continued to be one of the best projectors available for some time. The Lumière claw drive, however, was not as satisfactory as the Maltese-cross type used on some projectors from about 1870 and adopted by Edison for the camera, and it gradually yielded to the newer models. The Lumières continued to maintain a lively interest in motion picture developments even after their success with the camera and projector. In 1897 they devised a safety condenser as a protection against the fire hazard; in 1898 a peep-show viewing model, and in 1903 they began a study of the possibilities of direct photographing of colors. This research led to a good color process which was later introduced commercially. In England, Robert William Paul (1869–1943), scientific instrument-maker, who was the son of a London ship owner, was asked by George Georgiades and George Trajedis, two Greeks, to duplicate the Edison Kinetoscope. Georgiades and Trajedis had bought Kinetoscopes in New York from Holland Bros., eastern agents of the first Kinetoscope Company and brought them to London where they were exhibited in October, 1894, at a store in Old Broad Street. Paul inspected the Kinetoscope and knew he could copy it. But he did not believe he was free to do so, feeling sure that Edison had already patented the machine in England. Investigation showed that no such action had been taken. Thereupon at his work shop in Hatton Garden, London, Paul made Kinetoscopes for the two Greek exhibitors and also for himself. With his own machines he opened a display at Earl’s Court, London. Soon Paul began work on a camera and projector based on the Kinetoscope peep-show device.
