The fates of the Siberian scientists in the GULAG epoch

In the article the authors collective has studied the files on B.E.Petri, P.S.Mikhno, E.I.Titov, the Siberian scientists, which are kept in the FSB archive funds. Those scientists had different social background, education and labor careers, but their research paths many times met on field roads, in university auditoriums and in museum storages. The common feature for them was that their lives were tragically ended off by volleys of firing squads; these volleys were the acts illustrating annihilation of minds, dangerous for Stalin's satanic regime.
