Mary Tyler Peabody Mann (1806-1887) was born in Cambridge, Massachusetts, and died in Jamaica Plain, Massachusetts. In the late 1820s and early 1830s, she worked in Cuba as a governess on a coffee plantation, substituted as an assistant at Amos Bronson Alcott's Temple School, established schools of her own in Salem, Massachusetts, and wrote books for children, including The Flower People: Being an Account of the Flowers by Themselves (1842). Her other notable writings include: Christianity in the Kitchen: A Physiological Cook-Book (1857), and Life and Works of Horace Mann (1865). She wrote on childcare, kindergarten, and women's suffrage. Peabody married Horace Mann, an American education reformer and politician, in Boston, Massachusetts, in 1843. She wrote to Mary Baker Eddy in 1885, looking to purchase Eddy's Science and Health with Key to the Scriptures directly from her. There is no record of her studying with Eddy or uniting with The First Church of Christ, Scientist, in Boston, Massachusetts.
