Dziga Vertov

David Abelevich Kaufman (2 January 1896 – 12 February 1954) — also known as Denis Kaufman or his pseudonym Dziga Vertov or Vertof (, "spinning top") — was a Soviet pioneer documentary film and newsreel director, as well as a cinema theorist. His filming practices and theories influenced the cinéma vérité style of documentary movie-making and the Dziga Vertov Group, a radical film-making cooperative which was active in the 1960s.
