Frank Gray (13 September 1887 – 23 May 1969) was a physicist and researcher at Bell Labs who made numerous innovations in television, both mechanical and electronic, and is remembered for the Gray code.
The Gray code, or reflected binary code (RBC), appearing in Gray's 1953 patent, is a binary numeral system often used in electronics, but with many applications in mathematics.
Gray conducted pioneering research on the development of television; he proposed an early form of "flying spot scanner" for early TV systems in 1927, and helped develop a two-way mechanically scanned TV system in 1930.
With Pierre Mertz, Gray wrote the classic paper on the mathematics of raster scan systems in 1934. He later participated in the early days of the digital revolution, with Raymond W. Sears, William M. Goodall, John Robinson Pierce, and others at Bell Labs, by providing the binary code used by Sears in his PCM tube, a beam deflection tube of the type that Sears and Pierce collaborated on, which was used in Goodall's "Television by pulse code modulation".
