Dziga Vertov (b. 1896, Bialystok, Russian Empire–d. 1954, Moscow, USSR) was a pioneering Soviet filmmaker, whose films and manifestos played a central role in 20th century documentary, experimental film, and political cinema traditions. Working in the USSR in the 1920s–1950s, Vertov led the radical Kino-Eye (Cine-Eye) collective, which championed a new film language that would draw on the unique mechanical and audiovisual properties of cinematography, rather than on theatre or literature traditions. His polemical resistance to narrative fiction films contributed to the development of avant-garde documentary techniques in the Soviet Union and abroad. Long after Vertov fell out of favor in his native country, his work continued to influence international documentary cinema and political media groups. Born as David Abelevich Kaufman, Dziga Vertov adopted his pseudonym in early adulthood, and his subsequent work often blurs the lines between the filmmaker’s personal experiences and ideas ascribed to his alter ego. This split between Vertov’s personal life and his constructed persona reflected his belief that cinema, too, could simultaneously document observed reality and construct an entirely new reality from captured slices of life. Vertov maintained that filmmakers should seek out and expose the hidden social and political forces that govern life, using moving images and sound to shape spectator consciousness. His films were in dialogue with several avant-garde art movements, and he often experimented with different film techniques in hopes of both depicting and transforming reality. Moreover, Vertov argued that media technology, especially the movie camera and the wireless radio, would radically change how human beings navigated the world and how they understood their place in society. His theoretical writings are foundational to the discipline of film studies and to writings on film cinematography and montage. His seminal 1929 film Man with a Movie Camera (Chelovek s Kinoapparatom) is a cornerstone of film courses worldwide.
