Catharine MacKinnon
Feminists have been crucial to the development of the notion of sexual harassment and the codification of laws against sexual harassment. Catharine MacKinnon was among the first to write on the topic of sexual harassment. MacKinnon's book "Sexual Harassment of Working Women: A Case of Sex Discrimination" is the eighth most-cited American legal book published since 1978, according to a study published by Fred Shapiro in January 2000.
