Frances Ellen Watkins Harper was an African-American abolitionist, a suffragist, a poet, and an author. Attaining commercial success with the 1854 publication of Poems on Miscellaneous Subjects, Harper used her fame to publicly speak out against slavery and covertly assist the Underground Railroad. Harper became more involved in feminist causes after the Civil War ended, but became disenchanted with the movement's focus on white women and ultimately co-founded the National Association of Colored Women.
