Iuda Grossman

Iuda Solomonovich Grossman (7 February 1883 – 6 June 1934), also known by his pen name Iuda Roshchin, was a Ukrainian anarchist-communist and art critic. During the 1905 Revolution, he led the Black Banner organisation in Białystok and became a vocal critic of anarcho-syndicalism after the death of his brother Abram Grossman. After the revolution was suppressed, he fled into exile, where he joined the internationalist opposition to World War I. He returned from exile during the 1917 Revolution and became a supporter of the Bolsheviks, for which he was labelled a "Soviet anarchist". He later became a literary critic for the Russian Association of Proletarian Writers.
