Naum Gabo
Russian sculptor, 1890-1977
Naum Gabo was an influential sculptor, theorist, and key figure in Russia's post-Revolution avant-garde and the development of twentieth-century sculpture. His work combined geometric abstraction with a dynamic organization of form in constructions, monumental public sculpture and pioneering kinetic works. Responding to the scientific and political revolutions of his age, Gabo led an eventful life, moving to Munich, Oslo, Moscow, London, and finally the United States, and within the circles of the major avant-garde movements of the day, including Cubism, Futurism and Constructivism.
