Adeline Dutton Train Whitney (1824-1906) was an American poet and writer. She wrote mainly for young girls, championing conservative values, and purveying the message that a woman's happiest place is in the home, which is the source of all goodness. This proved very popular among parents, and her books sold extremely well throughout her life. Whitney was a staunch opponent of women's suffrage, though took no part in public life (in accordance with the message of her books). Aside from her writing, she patented a set of alphabet blocks for children.
