Georgi Vins (1928-1998) was a leader of Russian Baptists who was imprisoned for some years in the Soviet Union in the 1960s and 1970s. He later discovered that his father Peter was executed by the NKVD in 1936. He was expelled from the Soviet Union in 1979 following intervention by U.S. President Jimmy Carter. Part of his story is found in Michael Bourdeaux (1971), Faith on Trial in Russia (London: Hodder and Stoughton).
