About A Vindication of the Rights of Woman (Book Jacket Status: Not Jacketed) The first great manifesto of womenâs rights, published in 1792 and an immediate best seller, made its author the toast of radical circles and the target of reactionary ones.
In 1872, Stone and Blackwell became co-editors of the weekly suffragist publication Woman's Journal, which Stone had helped to found in 1870 (their daughter Alice later became editor). Stone continued to be active in the cause of women's rights almost until her death from cancer in Dorchester, Massachusetts in 1893.
