In securing the Democratic presidential nomination this week, Hillary Clinton made history, becoming the first women to ever achieve that feat in the United States. It is the latest in a long line of watershed moments for women. It now seems appropriate to take some time to acknowledge a few of the other fearless females who broke down barriers.
