This series contains records relating to the Spirograph projector. The Spirograph projector was originally designed in England in 1913 by Theodore Brown (1870-1938), who sold the rights to Urban in the early 20th century. Urban’s engineer Henry Joy (b. 1872) developed the Spirograph from 1920, and some were produced in 1923 shortly before the collapse of Urban’s business. It used 10½ inch diameter discs containing 1200 frames arranged in a spiral of twelve rows. When the handle was turned, the disc revolved and gradually tracked across behind the lens. The discs were reproductions of professional feature films and the projector was intended for home use.
The materials in this series include press articles, technical notes, correspondence, photographs and publicity materials.
