The Radio Nurse (and Guardian Ear) designed by Isamu Noguchi for Zenith Radio was the first baby monitor - released in 1937.
"Noguchi’s design manages to be both abstract and figurative at the same time. It looks like a faceless bust with the suggestion of a nurse’s cap in back, but also like an Art-Deco radio. It represented his exploration of the the notion of the interchangeability of biological and machine forms, and well as his concept of everyday objects as sculpture. Also, the speaker grille is reminiscent of the Japanese Kendo mask, and is typical of Noguchi’s combination of Eastern and Western forms."
