Which of these people played a major role in helping to gain women the right to vote?

Votes for women were first seriously proposed in the United States in July, 1848, at the Seneca Falls Woman's Rights Convention organized by Elizabeth Cady Stanton andLucretia Mott. One woman who attended that convention was Charlotte Woodward. She was nineteen at the time. In 1920, when women finally won the vote throughout the nation, Charlotte Woodward was the only participant in the 1848 Convention who was still alive to cast her vote. Eighty-one years old, she cast her vote proudly.
