WARENS, LOUISE-LANORE DE LA TOUR DU PIL, BARONNE DE

(baroness of) born 1700, Vevey, Switz. died 1762, Chambry, Savoy benevolent aristocrat who engaged the philosopher Jean-Jacques Rousseau in an idyllic liaison from 1728 to 1742, furthering his education and social position as his lover and maternal protectress. Married at a young age to the Baron de Warens, she left her husband and became a convert to Catholicism. Her many business ventures, which included a silk stocking factory, were failures. She sought the protection of King Victor of Savoy, who engaged her in political espionage and the conversion of Protestants. Among her converts was the young Rousseau, who met her at Annecy in Savoy when he was 16 and in flight from his engraver's apprenticeship in Geneva. After resuming his vagabondage, Rousseau returned in 1733-on foot-to Mme de Warens at Chambry, and she, 12 years his senior, formally proposed their affair, installing him at her country house Les Charmettes, where he remained on and off until 1742. Rousseau admired her instinctive morality and natural religion. He shared her favours with her steward Claude Anet; after Rousseau's long absence resulting from illness, she acquired a new and younger lover but retained an affectionate solicitude for Rousseau's welfare. When Rousseau last visited her in 1754, she gave her ring to his wife Thrse, assuming the final role of Maman ("Mama"), which he had always called her.
