Dziga Vertov
Dziga Vertov was born as Denis Abramovich (later changed to Arkadievich) Kaufman to a Jewish book-dealer's family. His younger brothers, renowned Soviet documentary filmmaker Mikhail Kaufman and cameraman Boris Kaufman, would later establish their own niches in film history. As a child he studied piano and violin, and at the age of ten began to write poetry; Vertov's films would reflect these early interests.
