Women like Hopper, Payne and many others had to push back against the social norms of their day, breaking down the barriers of what society thought women could do. They were often excluded and marginalized along the way. Some of them were even demonized for making choices that would have been seen as commonplace for men. In the face of these huge challenges, they still managed to make groundbreaking discoveries, advocate for human rights and change the world. To be clear, none of these women were perfect, and many of them had notable flaws, but there is still plenty to celebrate in their remarkable lives.
