This opera-loving New Yorker has always spoken her mind; as a young lawyer, RBG advocated for gender equality and women’s rights when few others did. She gained attention for the cases she won when arguing in front of the Supreme Court, before taking her place on the bench in 1993. Author Patricia Brennan Demuth answers all the question about what makes RBG so notorious and irreplaceable.
