French sculptor, draughtsman and printmaker of Belorussian birth.
He spent his childhood in Smolensk in a circle of cultured and assimilated Jews. His father was a convert to the Orthodox Church, and his mother came from an immigrant family of Scottish shipwrights. While staying with his mother’s relatives in Sunderland, northern England, in 1905, he attended the local art school and taught himself to carve furniture ornaments. At the age of 16 he continued his artistic training in London, taking evening classes in life drawing and making his living as an ornamental woodcarver. During this time he became friendly with the painter David Bomberg. He continued his studies at the Regent Street Polytechnic, London, and later, in 1908, at the Central School of Arts and Crafts, London, where he concentrated on techniques in wood.
