This was a tragic loss, and it set the tone for the entire genre. From an early age, Asimov was drawn to the communal aspects of fan culture, but he made it more difficult for women to experience that sense of community. Women have long occupied an ambiguous place in science fiction, where they have been alternately welcomed, dismissed, and harassed. Asimov took advantage of what he called the rising percentage of “shrill young girls” at conventions in the 1960s, and his unique position at such events—he was invariably the center of attention—made his example especially insidious. His admirers looked to him as a model of how to behave, and fandom was complicit for years in his serial misconduct in ways that have never been fully acknowledged.
