Harriet Winslow Sewall (1819–1889) was an American poet, and editor of the collected letters of Lydia Maria Child.
Harriet Winslow was born in Portland, Maine on June 20, 1819 into a Quaker family. She was educated in Portland and at a boarding school in Providence, Rhode Island. She was, at least in her early years, interested in transcendentalism and animal magnetism; and arguably more practically engaged with contemporary anti-slave and women's rights movements.[1]
She wrote poetry from an early age, and for many years; but apparently for her own satisfaction and without a view to publication. A number of her works were published, however, and has been republished in a number of collections of American poetry.[1]
She married in 1848 Charles Last, a journalist working on the Commonwealth newspaper. He soon became ill, relinquishing his job and placing the burden of support on Harriet, who was assisted by her relatively wealthy family. Charles died in 1856.[1]
In 1857 she married a Mr. Sewell and in 1861 her father died, providing her with a "moderate fortune" enabling her to pursue philanthropic interests. The couple divided their time between Melrose, Massachusetts and Boston, Massachusetts. They were both early members of the New England Women's Club, a Women's suffrage organisation.[1]
In 1882[2] she arranged for publication the letters of her friend, the author Lydia Maria Child.[1]
Mr. Sewell died on December 20, 1888. She died soon after, struck by an express train whilst crossing a railtrack.[1]
A collection of her poems was published in November 1889.[1]
