Mary Daly was an American radical feminist philosopher, academic, and theologian. Daly, who described herself as a "radical lesbian feminist", taught at Boston College, a Jesuit-run institution, for 33 years. Daly consented to retire from Boston College in 1999, after violating university policy by refusing to allow male students in her advanced women's studies classes. She allowed male students in her introductory class and privately tutored those who wanted to take advanced classes.
