Richard Franz Joseph Heuberger (1850-1914) was an Austrian composer of operas and operettas, a music critic, and teacher. Although Heuberger wrote many operas, ballets, choral works, and songs, he is best known today for his operetta Der Opernball, which he composed in 1898. The most famous number from the opera is the waltz duet "Komm mit mir ins Chambre séparée" (known colloquially as "Im Chambre séparée").
