Susan Brownell Anthony (February 15, 1820 – March 13, 1906) was an American social reformer and women's rights activist who played a pivotal role in the women's suffrage movement. Born into a Quaker family committed to social equality, she collected anti-slavery petitions at the age of 17. In 1856, she became the New York state agent for the American Anti-Slavery Society.
In 1878, Anthony and Stanton arranged for Congress to be presented with an amendment giving women the right to vote. Popularly known as the Anthony Amendment and introduced by Sen. Aaron A. Sargent (R-CA), it became the Nineteenth Amendment to the U.S. Constitution in 1920.
