The pseudonym of nineteenth-century French author and feminist, Amantine Lucile Aurore Dupin, baronne Dudevant. Sand was a prolific and immensely popular writer of fiction, drama, travel accounts, and correspondence as well as autobiographical work. A political writer during the French Revolution of 1848, she was critical of the Napoleonic Code for its inequitable treatment of women. Unhappy in her marriage, she separated from her husband and pursued an unconventional lifestyle that included dressing as a man and affairs with many lovers, most notable being the composer Frédéric Chopin. A few of the best known among her many works include Indiana (1832), Valentine (1832), Lélia (1833), Consuelo (1842-1843) and its sequel La Comtesse de Rudolstadt, (1843-1844), Jeanne (1844), and Marianne (1876).
