Summary
Frederic Eugene Ives was born in Litchfield, Connecticut in 1856. Ives was head of the Cornell University photographic laboratory. At Cornell he began developing the halftone printing process, which allowed the continuous tones of photographs or drawings to be translated into a series of minute dots. Ives inventions include the Trichromatic camera, Kromskop color camera and optical viewer, the Parallax Stereogram, and Hi-Cro Colro Processor. In the late 1920s he developed Polychrome, a two color process. Papers include correspondence, journals, speeches, articles, scrapbooks, patents, clippings, and other papers relating to the inventions of Ives and his son, including improved photographic methods and equipment, such as aerial and color photography, telephoto techniques, and other devices and techniques which were precursors of commerical television.
