Deaths: Co-inventor of the television remote control – Robert Adler

By

Robert Adler, a physicist and prolific inventor best known as the co-inventor of the television remote control, died Feb. 15 in Boise, Idaho. He was 93. The cause was heart failure, said his wife, Ingrid Adler. He designed the Space Command ultrasonic remote control, which used high-frequency sound, to change channels that was introduced by Zenith in 1956.

Adler, who held nearly 200 United States patents, worked at Zenith Electronics on and off for nearly 60 years. He was director of the research division during an era when consumer electronics companies like Zenith and RCA operated fully staffed research laboratories on par with AT&T’s Bell Laboratories.
