description Robert Adler Overview
Robert Adler was an Austrian-American electrical engineer and inventor who co-created Zenith's Space Command television remote control, introduced in 1956. The system used ultrasonic sound generated by mechanical components in the handset rather than a wired connection, allowing users to control functions such as channel selection and volume from a distance. Adler's work is significant in the history of consumer electronics because it helped establish the practical wireless television remote.
help Robert Adler FAQ
What did Robert Adler invent?
Robert Adler co-created Zenith's ultrasonic Space Command television remote, introduced in 1956. Instead of infrared signals, it used high-frequency sounds produced by mechanical controls inside the remote.
How did the 1956 Space Command remote work?
Pressing its buttons generated distinct ultrasonic tones that the television detected as commands. The system could change channels, adjust volume, and perform other tuning functions without a physical cable.
Who worked with Robert Adler on the Zenith remote?
Adler's work followed Zenith engineer Eugene Polley's earlier wireless remote-control development. Adler's 1956 Space Command design made ultrasonic control practical and reliable for television viewers.
Why was Robert Adler's remote important before infrared remotes?
It provided a wireless television-control system without the light-based electronics used by later infrared remotes. That made channel and volume control more convenient at a time when television sets were becoming common in American homes.
