Life

Sergey Semyonovich Gumberg was born in Ukraine. His father was a rabbi in Elizavetgrad and his brother, Alexander Gumberg emigrated to the United States in 1902.

Zorin aligned himself with the Left Opposition. He travelled to Ivanova with Alexander Voronsky in 1927, which was used as a pretext for Voronsky's expulsion from the Communist Party.

He was arrested on 1 January 1935, and sentenced to 5 years' imprisonment on 26 March that year in the Monastery of Saint Euthymius, then a prison in Suzdal. He was shot on 10 September 1937.
