Margaret Sanger - in 1999, in December I asked a waitress in the East Village who she thought the most important person of the century was she answered Margaret Sanger!. She was right!. Sanger founded Planned Parenthood and made it possible for women to control their own lives and their own sexuality!. Women are more than half the population so I think its a valid choice!.Www@QuestionHome@Com
