Charriere, Or Charrieres, Isabelle Agnete Dc Saint-Hyacinthe De, a French authoress, born at Utrecht, Holland, about 1740, died near Neuf-chatel, Switzerland, Dec. 27, 1805. She was the daughter of a Dutch baron, and married M. de Charriere, a poor Swiss gentleman who had been her brother's teacher. She published her first novel, Lettres neuclidteloises, in 1784, and in 1786 appeared her most famous work, Caliste, ou lettres ecrites de Lausanne. She visited England and France, and was an intimate friend of Benjamin Constant until the latter transferred his friendship to Mme. de Stael. She was a beautiful and brilliant woman; and Sainte-Beuve alludes in the highest terms to her genius in his Galerie'de femmes celebres. Owing to the loss of part of her fortune and friends, she spent the latter part of her life in great seclusion. A new edition of her Caliste appeared in 1845, with a notice by Sainte-Beuve, and with the latter's essay on Benjamin Constant et Madame de Charriere. Among her other writings are Lettres de Mistress Henley, a sequel to Benjamin Constant's Mart sentimental; Aglionette et Insi-nuant, a story; and the playsL' Emigre, Letoiet le rous, L'Enfant gate, and Comment linommc-t-on. Under the pseudonyme of Abbe de la Tour she published Les trois femmes, Sir Walter Finch et son fits William, and other works, of which a complete edition appeared in Leip-sic in 1798. Many of her works have been translated into German by her friend Ludwig Ferdinand Huber, and she wrote some of them in that language.
