Legal battles for gender equality didn’t begin with the Women’s Movement of the 1960s. But it laid the groundwork for the historic 1972 Supreme Court decision that made gender discrimination unconstitutional. That case was successfully argued by then-38-year old Brooklyn-born attorney Ruth Bader Ginsburg. It set precedent for another ruling a few years later that men should also be eligible for their wives’ survivor benefits. She won five out of the six gender discrimination cases she argued before the Supreme Court.
