Before Disney princesses were singing about equal pay, feminist journalist Gloria Steinem was marching and speaking out for women's rights. And at 80 — today's her birthday! — Gloria continues to be a driving force for the cause. In recent years, she's performed at Chime For Change, a global campaign for girls' and women's empowerment; made an appearance in the MAKERS documentary; and cofounded the Women's Media Center. The social and political activist has been an icon for women's rights, having been deeply involved in abortion issues, women's equality, and sex education. In honor of her birthday, take a look at some of Gloria's most powerful words on womanhood.
