Ives gained his PhD in physics from Johns Hopkins University, Baltimore, Maryland, and subsequently served in the US Signal Corps, eventually gaining experience in aerial photography. He then joined the Western Electric Engineering Department (later Bell Telephone Laboratories), c.1920 becoming leader of a group concerned with television-image transmission over telephone lines. In 1927, using a Nipkow disc, he demonstrated 50-line, 18 frames/sec pictures that could be displayed as either 2 in.×2 1/2 in. (5.1 cm×6.4 cm) images suitable for a "wirephone", or 2 ft ×2 1/2 ft (61 cm×76 cm) images for television viewing. Two years later, using a single-spiral disc and three separately modulated light sources, he was able to produce full-colour images.
