Orchestre de la Société des Concerts du Conservatoire
As a conductor, Messager held prominent positions in Paris and London, at the head of the Opéra-Comique, the Paris Opéra, the Orchestre de la Société des Concerts du Conservatoire, and the Royal Opera House, Covent Garden. Although as a composer he is known chiefly for his light works, as a conductor he presented a wide range of operas, from Mozart to Richard Strauss, and he acquired a reputation as a conductor of Wagner. In Paris he conducted the world premieres of Debussy's "Pelléas et Mélisande", Massenet's "Grisélidis" and Charpentier's "Louise". At Covent Garden, he gave the British premieres of operas by Saint-Saëns and Massenet.
