U.S. abolitionist.
She was principal of the Young Ladies' High School in Boston from 1828 to 1830, when she married Henry Chapman, a Boston merchant. In 1832, with 12 other women, she founded the Boston Female Anti-Slavery Society. Later she became chief assistant to William Lloyd Garrison , helping him to run the Massachusetts Anti-Slavery Society and to edit The Liberator , a widely circulated abolitionist publication. In 1839 she published a pamphlet arguing that the divisions among abolitionists stemmed from their disagreements over women's rights.
