Frank Gray (researcher)
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,
Gray conducted pioneering research on the development of

Patents
With Herbert E. Ives as co-inventor, Gray filed for two US patents in 1927: "Electro-optical system" (US 2,037,471, issued 14 April 1936) and "Electro-optical transmission" (US 1,759,504, issued 20 May 1930), and one in just his own name: "Television system" (US 2,113,254, issued 5 April 1938). He patented many other similar-sounding inventions over the years that followed.
His 1953 patent "Pulse Code Communication" with the Gray code was filed in 1947.[1]
