Theremin worked at the Moscow Conservatory of Music[31] for 10 years where he taught, and built theremins, electronic cellos and some terpsitones (another invention of Theremin).[27] There he was discovered by Harold Schonberg, the chief music critic of The New York Times, who was visiting the Conservatory. But when an article by Schonberg appeared mentioning Theremin,[32] the Conservatory's Managing Director declared that "electricity is not good for music; electricity is to be used for electrocution" and had his instruments removed from the Conservatory.[22] Further electronic music projects were banned, and Theremin was summarily dismissed.[33]
