Which Soviet mathematician was interrogated by the KGB as a result of his or her work, Sergei Novikov or Bella Subbotovskaya?
Bella Subbotovskaya Bella Abramovna Subbotovskaya (b. 1938 - d. 23 September 1982) was a Soviet mathematician who founded the short-lived Jewish People's University (1978–1983) in Moscow. The school's purpose was to offer free education to those affected by structured anti-Semitism within the Soviet educational system. Its existence was outside Soviet authority and it was investigated by the KGB. Subbotovskaya herself was interrogated a number of times by the KGB and shortly thereafter was hit by a truck and died, in what has been speculated was a assassination.
Tatyana Velikanova Tatyana Mikhailovna Velikanova (Russian: Татья́на Миха́йловна Велика́нова , 3 February 1932, Moscow – 19 September 2002, Moscow) was a mathematician and Soviet dissident. A prominent member of the human rights movement in the Soviet Union, she was for a long while an editor of "A Chronicle of Current Events", its underground periodical.
