One of the prominent figures known for their role in American women's suffrage is Susan B. Anthony. A staunch advocate for women's rights during the 19th century, Anthony dedicated her life to the cause of women's suffrage, equality, and social justice. She co-founded the National Woman Suffrage Association and played a vital role in organizing campaigns, giving public speeches, and advocating for the right to vote for women. Her efforts set the groundwork for the eventual passage of the 19th Amendment in 1920, granting women the right to vote in the United States.
