Alexander Aleksandrovic Vesnin (Russian: Александр Александрович Веснин) (1883, Yuryevets – 1959, Moscow), together with his brothers Leonid and Viktor, was a leading light of Constructivist architecture. He is best known for his meticulous perspectival drawings such as Leningrad Pravda of 1924.
In addition to being an architect, he was a theatre designer and painter, frequently working with Lyubov Popova on designs for workers' festivals, and for the theatre of Tairov. He was one of the exhibitors in the pioneering Constructivist exhibition 5x5=25 in 1921. He was the head, along with Moisei Ginzburg, of the Constructivist OSA Group. Among the completed buildings designed by the Vesnin brothers in the later 1920s were department stores, a club for former Tsarist political prisoners as well as the Likachev Works Palace of Culture in Moscow. Vesnin was a vocal supporter of the works of Le Corbusier, and acclaimed his Tsentrosoyuz building as 'the best building constructed in Moscow for a century'. After the return to Classicism in the Soviet Union, Vesnin had no further major projects.
