Lucy Stone (1818 - 1893) was an American suffragist and the wife of abolitionist Henry Brown Blackwell (1825-1909) (the brother of Elizabeth Blackwell). Born in West Brookfield, Massachusetts, Stone was educated at Oberlin College and became a leader of the women's suffrage movement, lecturing extensively on both suffrage and abolition. In 1870 she founded, in Boston, the Woman's Journal, the major publication of the women's rights movement at that time, and she continued to edit it for the rest of her life, assisted by her husband and their daughter. That daughter, Alice Stone Blackwell (1857-1950), wrote her biography, Lucy Stone: Pioneer of Woman's Rights (ISBN 0813919908), which was published in 1930 and again in 1971 (2nd edition).
Lucy Stone's refusal to be known by her husband's name, as an assertion of her own rights, was controversial then and is what she is remembered for today. Women who continue to use their birth namess after marriage are still known as "Lucy Stoners" in the U.S.
