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." The Haymarket affair, and the wrongful execution of anarchists in Chicago, radicalized her against the state and capitalism. She was also a prolific writer, and poet, publishing dozens of essays and poems in her short life.
