Lewis Tappan (May 23, 1788 – June 21, 1873) was a New York abolitionist who worked to achieve freedom for the enslaved Africans aboard the Amistad. Tappan was also among the founders of the American Missionary Association in 1846, which began more than 100 anti-slavery Congregational churches throughout the Midwest, and after the American Civil War, founded numerous schools and colleges to aid in the education of freedmen.
