Succeeding, however, at last, she had the courage to select the title-role of Phèdre, and she obtained a veritable triumph.
During her twenty-two years at this theatre, dividing the honors with her rival Marie Françoise Dumesnil, she filled many of the classical roles of tragedy, and created a great number of parts in the plays of Voltaire, Marmontel, Bernard-Joseph Saurin, de Belloy and others.
She retired in 1766, and trained pupils for the stage, among them Mlle Raucourt.
Oliver Goldsmith called Mlle Clairon "the most perfect female figure I have ever seen on any stage" (The Bee, 2nd No.); and David Garrick, recognizing her unwillingness or inability to make use of the inspiration of the instant, admitted that she has everything that art and a good understanding with great natural spirit can give her.
She was a mistress of Charles Alexander, Margrave of Brandenburg-Ansbach, who renovated his "White Castle" at his country seat and hunting estate in Triesdorf for her.
