The daughter of an actor, she married the actor Charles Chevillet Champmeslé in 1666, and by 1669 both were members of the Théâtre du Marais in Paris. In 1670 they joined the Hôtel de Bourgogne, where she had her first success as Hermione in Racine's Andromaque. Only with difficulty could Racine be persuaded by his friends to see the newcomer's debut, but after the performance he swore to write more roles for her. Thereafter her greatest triumphs were in such Racinian parts as the title role of Bérénice, Roxane in Bajazet, Monime in Mithridate, and the heroines of Iphigénie and Phèdre. Racine, who became her lover, tutored her in her parts and imparted to her the system of musical declamation he had developed. The art with which she employed her voice attracted playgoers, who came, according to Mme de Sévigné, to admire the actress, not the play. In 1679 she left the Hôtel for the amalgamated Molière-Marais company, which was to form the nucleus of the Comédie-Française (1680). She became the leading lady of the Comédie-Française, playing opposite Michel Baron.
