Katie Couric Instagram – Many of us owe a huge debt of gratitude to @gloriasteinem on this day, her 90th birthday. As the undisputed leader of second wave feminism, Gloria’s activism has paved the way on the path to equal rights. She is an unparalled advocate for social justice, reproductive rights and on top of that, she’s simply a remarkable human—kind, generous and compassionate. 💟 Gloria, we send you wishes for the happiest birthday today. But we are also sending you a giant thank you for everything you’ve done and everything you are. 🙌
