A history of the early days of science fiction fandom started with a small group of devotees who shared a common enthusiasm — but whose differences kept them in almost continuous conflict. Many of those early fans later became significant science fiction writers: Issac Asimov, Arthur C. Clarke, Ray Bradbury, Robert Heinlein, and others. Here, we see them at the beginning of their careers, expressing their points of view and opinions in battles, brawls, divisions, and break-ups, which seem as violent as the interplanetary wars they later wrote about.
