(Historic) Boris Porshnev
Boris Fedorovich Porshnev (March 7, 1905 - November 26, 1972) was a native Soviet historian who, in the 1950s, became interested in the possibility of a relict population of hominids surviving in modern times. He created a study group with several other Soviet scientists as a formal Commission of the Academy of Sciences of the U.S.S.R. The study group, which became known as the Soviet Snowman Commission, was most active between 1958 and 1959, when individuals such as Tom Slick flew into Moscow to meet secretly with the group.
Boris Porshnev authored many articles on the topic and co-authored one book with Bernard Heuvelmans that was published posthumously. Before his death he was known as one of the biggest advocates of the revolutionary, and highly controversial, theory that suggested Neanderthal Man still survives to this day, a hypothesis that is still argued by other students of hominology in Russia.
