prolific French novelist, best remembered for his collaborations with more famous writers.

As a young man, Sandeau became the lover of Amandine-Aurore-Lucie Dudevant (later known as George Sand) and worked with her on the novel Rose et Blanche (1831; “Red and White”), which was published under the pseudonym Jules Sand. At the end of 1832, she broke off the affair and adopted the pen name George Sand. Sandeau's most successful novel was Mademoiselle de la Seiglière (1848), a tale of the conflict between love and class consciousness, written in a mannered style, now read mainly for its portrayal of society during the reign of Louis-Philippe. He also wrote a good deal for the theatre. He met with considerable success with dramatizations of a number of his novels, and he collaborated with Émile Augier on several plays, including the famous Gendre de Monsieur Poirier (1854; “Son-in-Law of Monsieur Poirier”), which advocated the fusion of the new prosperous middle class and the dispossessed nobility.
