Frederick Douglass, Harriet Beecher Stowe, and William Lloyd Garrison were influential abolitionists in the 19th century. Frederick Douglass escaped slavery and worked to end it through his writings, including his autobiography. Harriet Beecher Stowe sought to prove slavery was wrong through her famous novel Uncle Tom's Cabin. William Lloyd Garrison founded the American Anti-Slavery Society in 1833 and published the influential anti-slavery newspaper The Liberator weekly for 35 years to spread the message of emancipation.
