Frederick Eugene Ives (1856–1937) was a U.S. inventor, born at Litchfield, Connecticut. In 1874–78 he had charge of the photographic laboratory at Cornell University. He moved to Philadelphia, Pennsylvania, where he was one of the founding members, in 1885, of the Photographic Society of Philadelphia.
Ives was a pioneer of color and stereoscopic photography, and demonstrated a system of natural color photography at the 1885 Novelties Exposition of the Franklin Institute in Philadelphia.
As early as 1900, Ives was tinkering with stereoscopic motion pictures. In 1903 Ives patented the "Parallax Stereogram" a method by which an image made up of interlaced stripes would animate when placed behind a stationary array of opaque, vertical bars and moved laterally. By 1923, he and fellow inventor Jacob Leventhal were producing a popular series of anaglyph 3-D novelty shorts called Plastigrams. The first one was for Educational Pictures, and the latter ones for Pathé Films.
