The Russian Revolution, the only—if only briefly—successful workers’ revolution took place in the era of photography and film, consequently thousands of hours of film footage from the revolutionary period existed. In the late 1920s, as the revolution’s red star was fading, a Russian-born man decided to collect as much as possible of the existing film—some of it shot by individuals, some by governments, some by new agencies, some by who-knows-who. Eventually, over 50 years this man collected some 271 motion picture film reels. He was a fanatic. Glad he was.
