Naum Gabo was the younger brother of Pevsner. He abandoned a medical career and began to study in Munich under the great art historian Heinrich Wolfflin. In 1910 he met Kandinsky and in 1913/4, while visiting his brother, then a Cubist painter in Paris, he met other artists and made his first construction in 1915. On returning to Russia in 1917, he found himself involved in art and politics/ He and his brother opposed Tatlin and in 1920 issued their 'Realistic Manifesto', which begins:
We deny volume as an expression of space ...'
Inevitably, he had to leave Russia and he spent the years 1922 - 32 in Berlin, leaving when the Nazis came to power. He had met Ben Nicholson and Barbara Hepworth in Paris, so he came to England and settled at St Ives in Cornwall. He spent many years here,broadcasting for the BBC during World War II, but in 1946 he moved to America.
His first public monument was a fifty-foot sculpture in Rotterdam (1957), but his works are mostly small constructions in glass, perspex, wire and similar materials. His gift to the Tate Gallery, London, includes many maquettes and also a large Fountain (1972), in the grounds of St Thomas's Hospital, London.
Other works by him are in New York (Met. Mus.) and other US museums. His Of Divers Arts was published in 1962.
