George Sand, the pen name of Amandine Aurore Lucile Dupin, is better known today for her Romantic idealism and her rebellion against 19th-century oppression of women than for her pioneering literary works. She was raised by her paternal grandmother, Marie Aurore de Saxe, at the latter's estate of Nohant in the province of Berry, France, and educated partly at a convent. In 1822, at the age of 18, she married Baron Casimir Dudevant, with whom she had two children. In 1831, she left her husband, went to Paris with her children, took a male pen name to claim equality with men, wore male attire, and lived a scandalous Bohemian life with lovers and friends. Among them was composer Frédéric Chopin. Her prolific works included the controversial novel Indiana (1832), which advocated free love. At the time of the 1848 Revolution, she moved to back to Nohant, where she continued writing. Sand wrote her autobiography in 20 volumes, Histoire de ma vie (The Story of My Life, 1855). Her private correspondence was edited and published posthumously.
