Mary Tyler Peabody Mann, born in 1807, was the wife of Antioch College president and educational reformer Horace Mann, and she shared her husband's views on education. Before their marriage, Mary Peabody joined with her sister, kindergarten movement leader Elizabeth Palmer Peabody, to establish a girl's school in Brookline, Massachusetts. Both Mary and her sister Sophia, whose husband was Nathaniel Hawthorne, were married at sister Elizabeth's West Street Bookstore in Boston. The Manns moved to Ohio in 1852 when he accepted the position at Antioch, and after his death, Mary returned to Boston. She remained active in social reform including suffrage, education reform, and American Indian rights.
