Clara Rockmore

In the 1920s, the Russian physicist Leon Theremin debuted an electronic instrument that could be played without any physical contact. Players stood in front of a box and waved their hands over antennas, summoning otherworldly sounds seemingly from thin air. The theremin might have been regarded as a passing novelty if not for the late Clara Rockmore, a virtuoso who helped to refine the instrument's design, and wowed concert hall audiences with her performances.
