Charles-Guillaume Étienne was a 19th-century French playwright. He was born in Chamouilley, Haute-Marne. He held various municipal offices under the Revolution and came in 1793 to Paris, where he produced his first opera, Le Rêve, in 1799, in collaboration with Antoine-Frédéric Gresnick. Although Étienne continued to write for the Paris theatres for twenty years from that date, he is remembered chiefly as the author of one comedy, which excited considerable controversy. Les Deux Gendres was represented at the Théâtre Français on 11 August 1810, and procured for its author a seat in the Académie française.
