Boris Popper

Boris V. Popper (December 19, 1904 – February 19, 2000) was a White Russian émigré living in Finland. He was one of the deported from Finland to the Soviet Union in April 1945. He later used the names Boris Berin-Bey and Batu Berin-Bey.

Popper wrote the book "Red Russian Meat Grinder" (fin. Venäjän Punainen Lihamylly) about his prison experiences under the pseudonym Boris Berin-Bey. The book was published by the Föreningen Veronica Association, founded by neo-Nazi Pekka Siitoin. Popper was the honorary chairman of the Turku Society for the Spiritual Sciences, founded by Siitoin, and he gave presentations at club events in the 1970s. In connection with the Kursiivi printing house arson lawsuit, Tiedonantaja magazine claimed that Popper had acted as a financier of Siitoin and acquired weapons and ammunition from the military's warehouses for the use of Siitoin's groups.
