Paul’s projector, called the Animatograph, had its first showing at the Finsbury Technical College on February 20, 1896. Eight days later it was demonstrated at the Royal Institute. Its success came to the attention of a theatreman, Sir Augustus Harris, operator of the Olympia Theatre. A deal was made by Harris with Paul and the projector rechristened the “Theatrograph.” After a short but successful run at the Olympia in London, the device was booked for two weeks at the Alhambra, Leicester Square. This motion picture show stayed there four years. Subjects projected at twenty pictures per second by the Paul device in the early programs were: “A Rough Sea at Dover,” a hand colored film; “Bootblack at Work in a London Street,” sporting events and many other scenes. Acres and Paul filmed the Derby of 1896, making some of the first successful topical pictures. Scenes showing the Prince of Wales’ horse, Persimmon, winning the Derby were exhibited at the Alhambra the evening after the race, creating a sensation and numerous curtain calls for Paul. The public was amazed. Paul continued to be interested in motion pictures, especially their scientific aspects, as a kind of hobby, for about 15 years. However, in 1912 he destroyed practically all his films and gave no further attention to the cinema. In addition to his early work in projection and camera design Paul himself had filmed many pictures including a series of animated drawings, _à la_ Walt Disney, to show electrical phenomena resulting from the approach of two magnets. These scientific films were made in association with Professor Silvanus Thompson. Paul also produced a number of comedies and used trick camera work to show motor cars flying to the moon and other bizarre effects. During World War I Paul invented secret war apparatus including an anti-aircraft height finder and anti-submarine device. Charles Pathé, a great name in the early French film world and carried on by several companies in the United States and elsewhere, bought one of the first Paul motion picture projectors. Previously he had roadshowed the Edison phonograph. Acres had a projector of his own called the Kinetic Lantern, which he said was finished in January, 1896, but the title was changed to Kineopticon and later to Cinematoscope for a special program for the Prince of Wales. Probably this projector also was made by Paul or he assisted in its design. Acres, however, was primarily interested in his profession of photography, and motion pictures appeared to him to be only one aspect of the subject. In 1897 he said: “There is something in photography and, in particular, in animated photography. Indeed, I think there can be no doubt that animated photography is destined to revolutionize our art-science, both as regards matters historical and scientific, in addition to giving us life-long portraits.” By the time Acres thus spoke the revolution was well under way.
