Robert Adler (
1913-
2007) was born in
Vienna, Austria. He earned a Ph.D. in
Physics from the
University of Vienna in
1937. After emigrating to the
United States, he began working in the
Zenith Electronics in the research division in
1941. In his lifetime, Alder was granted 180
patents for electronic devices. During
World War II, Alder worked on high-frequency
oscillators and
electromechanical filters in aircraft radios. Alder is known for his work in
surface acoustic wave technology used in color televisions and touch screens.
The invention Alder is best known for is the wireless remote control for televisions. While not the first remote control, Alder's remote control used sound to communicate with a television set instead of using light. It used aluminum rods struck by buttons on the device to produce high-frequency tones that would be interpreted to control functions by the television set. In the
1960s, Alder modified the remote control to use
ultrasonic signals.
By 1963, Alder risen to through the positions of Vice, President, and Director of Research at Zenith. He remained a technical advisor to Zenith until 1997. In 1980, Alder was awarded the IEEE's
Edison Medal. In 1997, Adler and
Eugene Polley were awarded an Emmy by the National Academy of Television Arts and Sciences. His most last patent application was filed February 1, 2007 for work on touch screen technology.
