A hundred years have passed since the masterpiece of David Wark Griffith, The Birth of a Nation, first appeared on the screens of America, in the winter of 1915. It demonstrated that the cinema, no less than literature and no less than the stage, could become a topic of serious critical, esthetic, intellectual, political, social, and technical discussion. In this way it brought the motion picture into a position of commanding influence in the social life of the American nation. The denunciation continues, and the storm over the film serves as a barometer of the global conflict, involving forces and issues set in motion by, but no means limited to, race. As Griffith's official biographer, Seymour Stern's main purpose of his book was to assemble, as extensively as possible, the rapidly vanishing record of what happened.
