[1] G. N. Frederiks was born in the Volga region, graduated from the Kazan Imperial University in 1911, and obtained his master's degree in mineralogy and geognosy (geology) from there in 1917.
"This title was to cause him angst in subsequent years and, apparently, be a contributing factor to his death at the hands of the NKVD".
At that time D. I. Mushketov was the director of the museum and head of the General Geology Department.
He was arrested February 24, 1935, and exiled for three years to corrective labour camps, from which he was released eight months early, after which he returned to his home in Leningrad.
He was arrested repeatedly after that and finally on June 13, 1937, was charged with deliberately misinterpreting the geological structure during explorations in the Chusovskie Gorodki Oil Field, and also with conspiracy to kill the leaders of the USSR.
