A Year: Day to Day Men: 20th of May
Within the Hedge
The Kinetoscope, an early motion picture exhibition device, was first publicly displayed on May 20, 1891.
First described in conceptual terms by Thomas Edison in 1888, the Kinetoscope was largely developed by Edison Labs employee William Kennedy Laurie Dickson between 1889 and 1892, leading most modern scholars to assign Dickson with the major credit for turning the concept into a practical reality.
Only sporadic work was done on the Kinetoscope for much of 1890 as Dickson concentrated on Edison’s unsuccessful venture into ore milling. By early 1891, however, Dickson, his new chief assistant, William Heise, and another lab employee, Charles Kayser, had succeeded in devising a functional strip-based film viewing system. In the new design, whose mechanics were housed in a wooden cabinet, a loop of horizontally configured 19 mm film ran around a series of spindles.
The film, with a single row of perforations engaged by an electrically powered sprocket wheel, was drawn continuously beneath a magnifying lens. An electric lamp shone up from beneath the film, casting its circular-format images onto the lens and thence through a peephole atop the cabinet. A rapidly spinning shutter permitted a flash of light so brief that each frame appeared to be frozen. This rapid series of apparently still frames appeared, thanks to the persistence of vision phenomenon, as a moving image.
Dickson, himself, starred in the first public demonstration, which was given on a prototype Kinetoscope at the laboratory for approximately 150 members of the National Federation of Women’s Clubs on May 20, 1891. When the women looked through the peephole, they saw a man who bowed his head, smiled, and waved his hands holding his hat. Dickson was the man in the 3-second-long movie, which is often referred to as “Dickson Greeting”.
The premiere of the completed Kinetoscope did not come until May 9, 1893, at the Brooklyn Institute of Arts and Sciences. Instrumental to the birth of American movie culture, the Kinetoscope also had a major impact in Europe; its influence abroad was magnified by Edison’s decision not to seek international patents on the device, facilitating numerous imitations of and improvements on the technology.
