Through the summer of 1889, W.K.L. Dickson and another Edison engineer, Charles A. Brown, tried to realize Edison’s plan for a photographic cylinder (below) on which to print moving images. They tried various emulsions, but each was either insufficiently light-sensitive or too grainy for the microscopic images. This photographic sheet, showing an Edison employee engaged in various “monkeyshines,” is one of only three that survive from these early experiments. By 1890, Dickson and William Heise had begun working on a machine that passed strips of film—actually emulsified paper—between two reels.
