Most Americans who made it past the fourth grade have a pretty good idea who Thurgood Marshall, Rosa Parks, and Martin Luther King, Jr., were. Not many Americans have even heard of Alice Paul, Howard W. Smith, and Martha Griffiths. But they played almost as big a role in the history of women’s rights as Marshall and King played in the history of civil rights for African-Americans. They gave women the handle to the door to economic opportunity, and nearly all the gains women have made in that sphere since the nineteen-sixties were made because of what they did.
