a French playwright and librettist. A frequent collaborator of Eugène Scribe, Delavigne was involved in the creation of the libretti of two of the earliest grand operas, Daniel Auber's La muette de Portici (1828) and Giacomo Meyerbeer's Robert le diable (1831). Amongst his later libretti were those for Fromental Halévy's Charles VI (1843) (co-authored with his brother Casimir) and Charles Gounod's La nonne sanglante (1854).
