Frances Harriet Whipple Green McDougall (1805–1878) was an abolitionist, poet, novelist, editor, botanist, spiritualist medium, and advocate of women's, voters', and workers' rights. In contrast to many other 19th-century women writers, throughout most of her adult life she earned her living as an author; at the same time she often donated her writing for causes she believed in, such as the abolition of slavery.
