French playwright who created the comédie larmoyante (“tearful comedy”), a verse-drama form merging tearful, sentimental scenes with an invariably happy ending. These sentimental comedies, which were precursors of Denis Diderot's drames bourgeois, were psychologically superficial and rhetorically exaggerated and were intended to contribute to the public's moral education. La Chaussée was the author of nine such plays—among them L'École des Mères (1744; “Mothers' School”), Mélanide (1741), and Le Préjugé à la mode (1735; “Stylish Prejudice”).

La Chaussée was the scion of a prosperous bourgeois family and did not embark on a literary career until his middle age; his first play, La Fausse Antipathie (“False Antipathy”), was written when he was 41 years old. From that time, however, he wrote steadily. In addition to the comédies larmoyantes, he produced other comedies and several tragedies. He was elected to the French Academy in 1736.
