Robert Adler, who designed the first non-visible light remote control.
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.
Zenith credits them as co-inventors, and the National Academy of Television Arts and Sciences awarded both Adler and Polley an Emmy in 1997 for the landmark invention.
