Susan B. Anthony (1820-1906) was a prominent American women's rights activist, suffragist, and abolitionist. She dedicated her life to fighting for gender equality and voting rights for women. Anthony co-founded the National Woman Suffrage Association with Elizabeth Cady Stanton and played a key role in the movement that eventually led to the passage of the 19th Amendment, granting women the right to vote in the United States. Her tireless advocacy and groundbreaking efforts have left a lasting impact on women's rights worldwide.
