He met George Sand, then Madame Dudevant, at Le Coudray in the house of a friend, and when she came to Paris in 1831 they had a relationship.
The intimacy did not last long, but it produced Rose et Blanche (1831), a novel written together under the pseudonym J.
Sand, from which George Sand took her famous pseudonym.
Sandeau continued to produce novels and plays for nearly fifty years.
His major works are:
Marianna (1839), in which he draws a portrait of George Sand
Le Docteur Herbeau (1841)
Catherine (1845)
Mademoiselle de la Seiglière (1848), a successful picture of society under Louis Philippe, dramatized in 1851
Madeleine (1848)
La Chasse au roman (1849)
Sacs et parchemins (1851)
La Maison de Penarvan (1858)
La Roche aux mouettes (1871)The famous play, Le Gendre de M.
Poirier, is one of several which he wrote in collaboration with Émile Augier—the novelist usually contributing the story and the dramatist the theatrical form.
At the suppression of this latter office, after the fall of the Second French Empire, he was pensioned.
Jules Sandeau died in Paris in 1883 and was buried in the Cimetière du Montparnasse.
