In the March 26, 1897 issue of the same publication, the British _Journal of Photography_, Donisthorpe also commented on his Kinesigraph: “The instrument was patented, made and worked before any other saw the light. I do not pretend the results were in all respects satisfactory. What first machine ever is?” Donisthorpe expressed surprise that some had not attempted to copy his machine which operated with a single moving lens and took pictures two and one-half inches in diameter on sensitized paper. This was later made transparent by the application of petroleum jelly or castor oil, a process which Eastman had used, for still pictures, with paper roll film in the United States from 1884 until his film base was developed late in 1889. Donisthorpe held that the continuous action with the moving lens providing the necessary intermittency was a decided advantage over other types: “In one particular, my own invention is so vastly superior even now to all that have come after it, that I am surprised practical men have not adopted it, now that it is open to the English public to do so.” As interesting as Donisthorpe’s idea was even in 1877 and also in 1889, it is very unlikely that his machine was satisfactory. Even now the intermittent motion picture camera and projector hold practical supremacy except in the case of very high speed photography for scientific purposes. Louis Aimé Augustin Le Prince (1842–1890), who worked in England, the United States and France, was the son of a French officer who was a friend of Daguerre, the pioneer in photography. Le Prince became a photographer, under the influence of Daguerre and in 1870 went to work in Leeds, Yorkshire, England, where he had his own shop. From shortly after 1880 to 1889 he was in the United States, returning then to Leeds. Le Prince proposed a multiple-lens camera-projector system. On January 10, 1888 he applied for an American patent, which was issued on November 16 of the same year, on a “Method of an apparatus for producing animated pictures of natural scenery and life.” In Le Prince’s method, two strips of sensitized paper or other material would be fed alternately through a camera and projector equipped with two sets of rotating lenses. It has been said that Le Prince also had an idea of a system using only one lens. Years later, at the trial of the American Mutoscope and Biograph Company against Thomas A. Edison, a model of the Le Prince camera-projector was introduced together with results purportedly made by Joe Mason of Biograph, but it was unsatisfactory--the double lens system did not produce evenly spaced pictures and each had to be printed separately. Furthermore, the background had to be treated specially or the figures would appear to jump right and left, because each lens took pictures from a slightly different angle.
