He studied for six years in Prague, and by the time he died on October 24, 1948 in Bad Ischl, had lived through all of the political and cultural convulsions of the first half of the twentieth century. The diversity of his oeuvre ranges from military music to operetta and opera.
He is most famous for his operettas – the most successful of which is The Merry Widow (Die lustige Witwe) – but he also wrote sonatas, symphonic poems and marches. He also composed a number of waltzes (the most popular being Gold und Silber, composed for Princess Pauline von Metternich's "Gold and Silver" Ball, January 1902), some of which were drawn from his famous operettas. Individual songs from some of the operettas have become standards, notably "Vilja" from The Merry Widow and "You Are My Heart's Delight" ("Dein ist mein ganzes Herz") from The Land of Smiles (Das Land des Lächelns).
