This electrically driven machine, displayed at the exhibit of Fontaine, a French engineer, showed pictures of animals in motion, as well as men and birds. The old photo stand-by of horses in motion in different gaits again was featured. This system rather pleased Marey, as he remarked that it would be hard to construct a better Wheel of Life, though Edison had even then accomplished it in his laboratory at West Orange, New Jersey. The limitations of the method, however, were fully recognized by Marey who mentioned the small number of images which could be shown, the restricted enlargement, and the intermittent movement troubles. Also, the device was noisy and the flicker had not been eliminated. Thus the year of 1889 brought together two great figures, Marey, a pure scientist whose zeal for learning about locomotion resulted in improvements in what was to be the motion picture art-science, and Edison who invented the first entirely practical motion picture camera and the first film peep-show device which was to be the inspiration for projectors as they were finally established, setting the pattern even to our day. _XV_ EDISON’S PEEP-SHOW _Edison turns to motion pictures--Donisthorpe of England works it all out on paper--Eastman manufactures film--Edison perfects a motion picture camera, the Kinetograph, and a peep-hole viewer, the Kinetoscope--World Premiere, New York--April, 1894._ In the laboratory of Thomas Alva Edison the development of a practicable motion picture camera and viewing apparatus was really achieved. Leadership in the magic shadow art-science came with Edison once again to the United States and it has not left this country since. As a sequel America and motion pictures are linked in the minds of millions throughout the world. Edison came to the motion picture through his Talking Phonograph, which he had developed not as an entertainment machine but as a device which would be a substitute for the court reporter and in other proceedings requiring exact recording. The motion picture experiments were made rather as a hobby and a diversion from more serious research and invention; the aim was to combine the automatic hearing and speaking of the phonograph with the sight and action of the motion picture. Curiously enough Plateau, a man who went blind, made the first motion picture possible; Edison who was quite deaf made a great contribution to recording and reproducing sound.
