Russian family of sculptors and designers. Vladimir (Avgustovich) Stenberg (b Moscow, 4 April 1899; d Moscow, 2 May 1982) and his brother Georgy (Avgustovich) Stenberg (b Moscow, 20 March 1900; d Moscow, 15 Oct 1933) were encouraged by their father, a painter, and worked closely together until Georgy’s death. They trained first at the Moscow School of Painting, Sculpture and Architecture, then continued their studies at the Free State Art Studios (Svomas) under Georgy Yakulov. They were founder-members of the Society of Young Artists (Obmokhu), which produced propaganda posters and urban decorations for revolutionary festivals. They contributed collaborative works to all four of the group’s exhibitions (1919, 1920, 1921, 1923); at the 1921 show they exhibited their three-dimensional constructions alongside Rodchenko’s hanging works. The Stenbergs joined the Institute of Artistic Culture (Inkhuk) in January 1920, becoming members of the First Working Group of Constructivists in 1921. In January 1922, together with Konstantin Medunetsky, they exhibited 31 works at the Kafe Poetov in Moscow and produced a declaration of Constructivist principles in the catalogue. Each work was entitled Construction of Spatial Structure and was envisaged as an experiment towards new types of utilitarian and architectural structures.
