Aurore's father died when she was very young, and she lived
        principally at Nohant in Berri with her grandmother, Madame Dupin, on
        whose death the property descended to her. At eighteen she was married
        to Casimir, Baron Dudevant, and had two children, and after nine years
        left her husband and went to Paris to make her living by literature in
        the Bohemian society of the period.
              When she first went to Paris, and with her companion Jules
        Sandeau, from the first half of whose name her pseudonym was taken, 
        settled to novel-writing, her books "Indiana" (1832), "Valentine" 
        (1832), "Lelia" (1833) and "Jacques", partook of the Romantic
        extravagance of the time, informed by a polemic against marriage.
              "Mauprat" (1837), a very fine novel, does not fit amongst her
        other works. Then she began to turn towards the studies of rustic
        life---"La Petite Fadette", "Francois le Champi", "La Mare au diable"
        (1846)---which some regard a third division in her works and are, by
        modern standards, her best works.
              Later her philosophical and political teachers engendered the
        socialistic rhapsodies of "Spiridon" (1838), "Consuelo" (1842-1844)
        and the "Comtesse de Rudolstadt" (1843-1845).
              For the best part of twenty years her life was spent in the
        company and partly under the influence of various more or less
        distinguished men. At first her interest were with poets and artists,
        the most famous being Alfred de Musset, with whom she travelled in
        Italy, and Chopin, who was her companion for several years. In the
        second decade her attention shifted to philosophers and politicians,
        such as Lemennais, the socialist Pierre Leroux, and the republican
        Michel de Bourges.
             After 1848 she settled down as the quiet 'chatelaine of Nohant',
        where she spent the rest of her life in outstanding literary activity,
        varied by travel. Amongst the miscellaneous works of her last twenty
        years---some of them, such as "Les Beaux Messieurs de Bois Dor‚", "Le
        Marquis de Villemer", "Mlle La Quintinie", are of high merit. Her
        complete works, over a hundred volumes, besides novels, plays, include
        the charming "Histoire de ma vie", "Hiver a Majorque", "Elle et luis"
        (on her relations with de Musset), and delightful letters published
        after her death.
