High Quality Content by WIKIPEDIA articles! The Vesnin brothers: Leonid Vesnin (1880–1933), Victor Vesnin (1882–1950) and Alexander Vesnin (1883–1959) were the leaders of Constructivist architecture, the dominant architectural school of the Soviet Union in the 1920s and early 1930s. Exact estimation of each brother`s individual input to their collaborative works remains a matter of dispute and conjecture; nevertheless, historians noted the leading role of Alexander Vesnin in the early constructivist drafts by the Vesnin brothers between 1923 and 1925. Alexander also had the most prominent career outside of architecture, as a stage designer and abstract painter.
