At his Military Collegium trial on 28 July 1938 he retracted the confession extracted from him, stating he had never belonged to the 'Polish Military Organisation', but the hearing lasted about twenty minutes and ended in a death sentence.

Born into a Jewish petty-bourgeois family in Mława, then in the Płock Governorate of the Russian Empire, he trained as an electrical engineer at the Higher Technical Courses in Warsaw and joined the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL) in 1900. Sources agree he was arrested repeatedly between 1902 and 1913 and spent years in Tsarist prisons and Siberian exile, but they differ on the number of arrests, recording six in some accounts and seven in others. In 1917 he sat on the Irkutsk Soviet as a Bolshevik, served on the Petrograd Soviet executive and the Military Revolutionary Committee during the October uprising, and was elected to the Constituent Assembly. From 1921 he was deputy chairman of the Cheka and later the GPU, and from 1925 to 1930 deputy chairman of the Revolutionary Military Council; arrested in 1937, he was shot in 1938 and rehabilitated in 1956.
