In 1949, the investigation of a large group of geologists, called the ”Krasnoyarsk Case”, resounded throughout the USSR. Twenty-seven people, including 4 academicians and corresponding members of the USSR Academy of Sciences and 10 professors, doctors of geological and mineralogical sciences, were put under investigation. The main accused was Joseph Grigoriev, who, according to the investigation, ”maliciously hid valuable mineral deposits from the Soviet state and deliberately directed research work along a false path”.
