Alice Paul

Paul often suffered police brutality and other physical abuse for her activism, always responding with nonviolence and courage. She was jailed under terrible conditions in 1917 for participating in a Silent Sentinels protest in front of the White House, as she had been several times during earlier efforts to secure the vote for women in the United Kingdom.
After 1920, Paul spent a half-century as leader of the National Woman's Party, which fought for the Equal Rights Amendment, written by Paul and Crystal Eastman, to secure constitutional equality for women. She won a major permanent success with the inclusion of women as a group protected against discrimination by the Civil Rights Act of 1964. Provided by Wikipedia
