The most famous of Strauss' operettas are Die Fledermaus, Eine Nacht in Venedig, and Der Zigeunerbaron. There are many dance pieces drawn from themes of his operettas, such as "Cagliostro-Walzer" Op. 370 (from Cagliostro in Wien), "O Schöner Mai" Walzer Op. 375 (from Prinz Methusalem), "Rosen aus dem Süden" Walzer Op. 388 (from Das Spitzentuch der Königin), and "Kuss-Walzer" op. 400 (from Der lustige Krieg), that have survived obscurity and become well-known. Strauss also wrote an opera, Ritter Pázmán, and was in the middle of composing a ballet, Aschenbrödel, when he died in 1899.
Strauss was diagnosed with pleuropneumonia, and on 3 June 1899 he died in Vienna, at the age of 73. He was buried in the Zentralfriedhof. At the time of his death, he was still composing his ballet Aschenbrödel.
