Fuller, Margaret, 1810–50, American writer, lecturer, and public intellectual, b. Cambridgeport (now part of Cambridge), Mass. She was one of the most influential personalities in the American literary circles of her day. A precocious child, she was forced by her father, a Massachusetts congressman, through an education that impaired her health but nonetheless gave her a broad knowledge of literature and languages. A stimulating talker, she conducted (1839–44) a series of conversation classes for society women in Boston on social, literary, historical, and philosophical topics.

While working for Greeley, she also wrote essays on the unfairness of marriage, abuses in asylums and prisons, and African-American and woman suffrage.

She sailed for England in 1846, and there became the first American female foreign correspondent. She also met and impressed such eminent writers as George Sand, George Eliot, Matthew Arnold, and William Wordsworth.
