Final answer:
Susan B. Anthony was a prominent women's rights activist and suffragist who co-founded the National Woman Suffrage Association. She is well-known for voting illegally in an 1872 election and her uncompromising advocacy for universal suffrage.
Step-by-step explanation:
Susan B. Anthony was a fearless crusader for women's rights, known for her activism in the suffragist movement. She played a substantial role in the fight for women's suffrage alongside other notable feminists including Elizabeth Cady Stanton, Lucy Stone, and Victoria Woodhull. Anthony's dedication to the cause led to her illegal vote in an 1872 senatorial election, for which she was tried and convicted, though she never paid the fine imposed upon her. Despite facing challenges, such as some activists distancing from women's suffrage to advance black enfranchisement, Susan B. Anthony believed in universal suffrage and was willing to take controversial stances to promote her cause. In 1869, she co-founded the National Woman Suffrage Association, which aimed to amend the Constitution to grant women the right to vote.
