He is best known for his libretti for Maurice Ravel's opera L'heure espagnole and for numerous operettas by Claude Terrasse.
In the late 1880s he contributed poems to the literary magazine Potache-Revue (potache being slang for 'schoolkid'), along with André Gide, Léon Blum, Pierre Louÿs, Maurice Quillot and others.
His literary pseudonym Franc-Nohain was derived from the Nohain river, where he had spent many happy hours as a child.
[2] He is best remembered now as the librettist for some operettas by Terrasse, and for the opera L'heure espagnole by Maurice Ravel, adapted from his own comedy.
He had two sons: the actor Claude Dauphin, and the songwriter and television producer/director Jean Nohain (aka Jaboune).
