Ernest Henri Alexandre Boulanger was a French composer of comic operas and a conductor. He was more known, however, for being a choral music composer, choral group director, voice teacher, and vocal contest jury member.

Marie-Julie Boulanger, née Marie-Julie Halligner, was a French mezzo-soprano. She performed her entire career under the stage name Mme Boulanger, appearing in the world premieres of Le maître de chapelle, L'ambassadrice, Le domino noir, and La fille du régiment.
