Léon Theremin
After 51 years in the Soviet Union Léon Theremin started travelling, first visiting France in June 1989 and then the United States in 1991, each time accompanied by his daughter Natalia, where he was reunited with Clara Rockmore who performed a number of concerts at this time. He also made a demonstration concert at the Royal Conservatory of The Hague in early 1993 before dying in Moscow in 1993 at the age of 97.
