Leon Theremin |
 | | The instrument was demonstrated for Vladimir Lenin, who was so impressed he ordered their mass production and asked Theremin to give him lessons. |
| | In 1927 Theremin emigrated to the United States, where he patented the "Thereminvox" (1928) and contracted with RCA to market and distribute them. |
| | During the '20s and '30s Theremin worked in New York and associated with high society, and his instrument gained fame thanks in part to the classical performances of Clara Rockmore. |
