Charles-Louis-Étienne Nuitter[1] was a French librettist, translator, writer and librarian born in Paris, France, on 24 April 1828.

He was a keen theatre-goer, and in the 1850s he started writing librettos, mainly vaudevilles, later opéras comique, operas bouffes, operettas and ballets.

Other translations include I Capuleti e i Montecchi, Oberon, Abu Hassan, Die Zauberflöte, and Verdi's Macbeth, Aida, La forza del destino and Simon Boccanegra.

[5] Becoming involved in the archives of the Paris Opera in 1863, he became official archivist there three years later, and ended his career in law (he had given legal advice to Offenbach in a dispute with the manager of the Théâtre des Bouffes-Parisiens prior to the 1864 premiere of La belle Hélène).

[2] Acquisitions by Nuitter included an important collection of theatre books by Joseph de Filippi and around 900 opera librettos from a former director of the théâtre, Nestor Roqueplan.
