The Fate of Boris Osipovich Dolgikh

Among the scholars who fell victim to the repressions in the early 1930s was one of our country's most outstanding ethnographers and historians, internationally known for his classical Siberian studies, Boris Osipovich Dolgikh. Unfortunately, until recently his tragic life history was known only to his inner circle. Staff members of the Division of the Far North and Siberia of the Institute of Ethnography, Soviet Academy of Sciences—a division he founded—even those who had known him for many years, did not know about this. He was motivated to keep certain chapters of his past under wraps so as not to damage prospects for the important work he was doing, work related to state policy toward the peoples of the North. The first biography of the scholar, containing a full accounting, was not published until 1992.1
