Editing Leon Theremin (section)

==Return to the Soviet Union==
Theremin abruptly returned to the [[Soviet Union]] in 1938. At the time, the reasons for his return were unclear; some claimed that he was homesick, while others believed that he had been kidnapped by Soviet officials. Beryl Campbell, one of Theremin's dancers, said his wife Lavinia "called to say that he had been kidnapped from his studio" and that "some Russians had come in" and that she felt that he was going to be spirited out of the country.<ref name="t">''[[Theremin: An Electronic Odyssey]]'', written, directed and produced by Steven M.

Many years later, it was revealed that Theremin had returned to his native land due to tax and financial difficulties in the United States.<ref>[[#G|Glinsky]].</ref> However, Theremin himself once told Bulat Galeyev that he decided to leave himself because he was anxious about the approaching war.<ref name="galeyev LMJ6">Bulat M.

Although rumors of his execution were widely circulated and published, Theremin was put to work in a ''[[sharashka]]'' (a secret laboratory in the [[Gulag]] camp system), together with [[Andrei Tupolev]], [[Sergei Korolev]] and other well-known scientists and engineers.<ref name="mattis1989"/> The Soviet Union said he was [[Rehabilitation (Soviet)|rehabilitated]], closing its case against him in 1956.
