Félix Augustin Joseph Vasseur, known as Léon Vasseur was a French composer, organist and conductor. While working as a cathedral organist, he turned to composing operettas and soon had a hit withLa timbale d'argent (1872). He wrote another thirty operettas but never repeated that early success. He also composed church music including two settings of the mass.
