Soviet Gadget Master:
Leon Theremin, the Russian inventor of the earliest fully electronic musical instrument, emigrated to the United States in the 1920s. Under mysterious circumstances -- possibly abducted by Soviet secret agents -- he returned to the Soviet Union in 1938. Detained in a Siberian labor camp, he was then forced to build covert listening devices, his most famous product begin the Great Seal bug whose ingenuity baffled Western experts. Released in 1956, Theremin died in Moscow in 1993. |
