"Zenith Electronics said Eugene Polley passed away of natural causes on Sunday at a Chicago hospital.
His 1955 invention, Flash-Matic, pointed a beam of light at photo cells on each corner of the TV, turning it off and on and changing the channels.
His invention was a luxury add-on in the days before hundreds of cable television channels.
Born in Chicago in 1915, Polley began his engineering career in 1935. He worked at Zenith for 47 years, earning 18 US patents."
