Margaret Sidney (1844–1924)

Margaret Sidney was the pseudonym of Harriett Mulford Stone. Sidney was her father's first name. In 1881, she married Daniel Lothrop, publisher and founder of the Boston firm D. Lothrop Publishing, and he published her now-classic series of Five Little Peppers books. After Lothrop's death, she ran the company for a while. Besides writing, Harriett had a great interest in history and historical homes and buildings, several of which she helped to preserve.
