Grigori Nickolaevich Tovstoles (1887−1957) is a figure of the Russian emigrant community who is virtually unknown in the present day Russia. G. Tovstoles fought in the White army during the Civil war and he was one of the earliest participants of the Eurasian movement in emigration and a member of several Masonic lodges. In 1946 Tovstoles who lived at that time in France accepted the Soviet citizenship. In 1951 Tovstoles was detained by the USSR Ministry of State security in the territory of East Germany. The article for the first time introduces into the scientific turnover materials of investigation against Tovstoles (these materials are kept in the Russian Federation Federal Security Service' archive).
