Marie-Emmanuel-Guillaume-Marguerite Théaulon de Lambert (14 August 1787, Aigues-Mortes – 16 November 1841) was a French playwright.
In 1814 he sang for the Bourbons and put on his first play, Les Clefs de Paris, ou le Dessert d’Henri IV (The Keys of Paris, or the Deservings of Henry IV), in their honour.
He collaborated on the royalist journals Le Nain rose, La Foudre, L’Apollon.
Written extremely quickly, most of them are only sketches, whose style often leaves something to be desired but which do not lack wit and beauty.
He wrote two five-act verse comedies, L’Artiste ambitieux (1820) and L’Indiscret ( 1825), both put on at the Odéon, which sometimes rise to comic truth.
