Pierre-Barthélemy Gheusi

Pierre-Barthélemy Gheusi, also known by the pseudonym Norbert Lorédan, (21 November 1865 – 30 January 1943) was a French theatre director, librettist, journalist and writer.

A son of a banker and distant cousin of Gambetta, Pierre-Barthélemy Gheusi studied at the college in Castres, where he met Jean Jaurès, who was at that time a tutor there, and became a friend of the doctor and scholar François de Vesian.

In 1887–1888, at the instigation of Laurent Tailhade, Gheusi worked on the revue Le Décadent, but his literary career struggled to take off, despite the recommendations of Émile Zola and Catulle Mendès.

Pedro Gailhard had called him to serve in the direction of the Paris Opéra in 1906 and in 1914, he became director of the l'Opéra Comique, alongside Émile and Vincent Isola.

In that year Anatole de Monzie, Minister of Public Instruction and Beaux-Arts, nominated him again Director of the Opéra-Comique which was in a financial crisis.
