August 26 is the 100th anniversary of the official certification of the ratification of the 19th amendment to the U.S. Constitution, which banned states and the federal government from denying the right to vote to citizens on the basis of sex. Jamaica Plain was an important place in the suffrage movement, where many women's-rights agitators made their home. Judith Winsor Smith, who lived in Jamaica Plain in the latter part of her long life, was a suffragist and abolitionist. When she voted for the first time, in 1920, at the age of 99, she was dubbed "the oldest suffragist of them all." In Jamaica Plain she lived with her daughter, Zilpha Smith, who was a pioneer in the development of the field of family social work in Boston.
