Today in Labor History June 20, 1912: Voltairine de Cleyre, one of the earliest feminist anarchists, died at the age 45, following a long illness. Two thousand supporters attended her funeral at Waldheim cemetery, in Chicago, where she was buried next to the Haymarket Martyrs. De Cleyre opposed capitalism and marriage and the domination of religion over sexuality and women’s lives. Her father, a radical abolitionist, named her after the Enlightenment writer and satirist, Voltaire. Her biographer Paul Avrich said that she was "a greater literary talent than any other American anarchist."
