Der Zigeunerbaron
19th century Viennese operetta was built on both the "singspiel" and the French model. Franz von Suppé is remembered mainly for his overtures. Johann Strauss II, the "waltz king", contributed "Die Fledermaus" (1874) and "The Gypsy Baron" (1885). Carl Millöcker a long-time conductor at the Theater an der Wien, also composed some of the most popular Viennese operettas of the late 19th century, including "Der Bettelstudent" (1882), "Gasparone" (1884) and "Der arme Jonathan" (1890).
