The co-inventor of the TV remote, Robert Adler, has passed away :(

The co-inventor of the TV remote, Robert Adler, has died.

Various sources have credited either Polley, another Zenith engineer, or Adler as the inventor of the device. Polley created the "Flashmatic," a wireless remote introduced in 1955 that operated on photo cells. Adler introduced ultrasonics, or high-frequency sound, to make the device more efficient in 1956.

Adler joined Zenith's research division in 1941 after earning a doctorate in physics from the University of Vienna. He retired as research vice president in 1979, and served as a technical consultant until 1999, when Zenith merged with LG Electronics Inc.

During World War II, Adler specialized in military communications equipment. He later helped develop sensitive amplifiers for ultra high frequency signals used by radio astronomers and by the U.S. Air Force for long-range missile detection.

Adler also was considered a pioneer in SAW technology, or surface acoustic waves, in color television sets and touch screens. The technology has also been used in cellular telephones.

The U.S. Patent and Trademark Office published his most recent patent application, for advances in touch screen technology, on February 1.

His wife, Ingrid, said Adler wouldn't have chosen the remote control as his favorite invention. In fact, he didn't even watch much television.

"He was more of a reader," she said. "He was a man who would dream in the night and wake up and say, 'I just solved a problem.' He was always thinking science."

Adler wished he had been recognized for more of his broad-ranging applications that were useful in the war and in space and were building blocks of other technology, she said, "but then the remote control changed the life of every man."

Rest in peace!!! -- Don't forget to press the "Sleep" button!!
