Eduard Petrovich Berzin (Russian: ????´?? ?????´??? ??´????, Latvian: Eduards Berzinš; 1894–1938), born in Latvia, was a soldier and Chekist, but is remembered primarily for setting up Dalstroy, which instituted a system of forced-labour camps in Kolyma, North-Eastern Siberia, where hundreds of thousands of prisoners died.
It was considered to be the most brutal of all the Gulag regions.
