Margaret Sidney

Harriett Lothrop was an American author also known by her pseudonym Margaret Sidney. In addition to writing popular children's stories, she ran her husband Daniel Lothrop's publishing company after his death. After they bought The Wayside country house, they worked hard to make it a center of literary life.

Harriett Mulford Stone was born in New Haven, Connecticut, in 1844. The daughter of New Haven architect, Sidney Mason Stone, she was “brought up in an atmosphere of culture and learning enhanced by free access to her father’s large library.” From early girlhood she “delighted in creating imaginary people”. She was educated at seminaries near her home and graduated from Miss Dutton's School at Grove Hall in New Haven in 1862. While a student there “she displayed such mental alertness, combined with retentive memory and a great imaginative and poetic talent that she was marked for future success.”

The success of Harriett's short stories prompted her to write Five Little Peppers and its 11 sequels. The original novel was first published in 1881, the year that Stone married Daniel Lothrop. Daniel had founded the D. Lothrop Company of Boston, who published Harriett's books under her pseudonym, Margaret Sidney.

Harriett and Daniel may have both had an interest in history and in famous authors. In 1883, they purchased the house in which both Louisa May Alcott and Nathaniel Hawthorne had lived. Nicknamed The Wayside, the house is located in Concord, Massachusetts. The year after Harriett and Daniel moved into the house, Harriett gave birth to their daughter, Margaret, at the age of 40.

Daniel Lothrop died on March 18, 1892, when Harriett was 48 and their daughter was just 9 years old. There was a gap in the release of the Five Little Peppers books from 1892 to 1897, while Harriett continued to run the publishing company Daniel founded. Eventually, she sold the company, which later became Lothrop, Lee & Shepard Co. It continued to publish Harriett's books under the name Margaret Sidney when Harriett resumed writing the Five Little Peppers series.

She died at the age of 80.

Harriett was an early member of the Massachusetts Society of the Daughters of the American Revolution (DAR). In 1894 she became the founder and first regent (president) of the newly formed Old Concord Chapter of the DAR in Concord, MA.

She loved traveling overseas, but spent many winters in California where the climate was more agreeable.

Alongside her writing career, Stone had a deep interest in historical homes and buildings and worked hard to preserve them. These include:

• The Wayside, where she lived with her family
• Orchard House, which belonged to the Alcott family and was next door to the Wayside
• Grapevine Cottage, where Ephraim Wales Bull developed the Concord grape
• The Tolman House in Dorchester, Massachusetts built during the colonial period

In later years, Stone's daughter Margaret Lothrop championed to have her childhood home, The Wayside, declared a National Historic Landmark. It was made so in 1963.
