Emmerich Kálmán (1882 - 1953)
A fellow student and contemporary of Bartók and Kodály, Imre Kálmán won success with his operettas. He lived for a time in Vienna, moving to Paris in 1939 and then to the United States of America, where he had success as a conductor. In 1949 he returned to Europe, living chiefly in Paris.
A number of operettas by Kálmán have become a central part of Viennese operetta repertoire, reflecting the spirit of their time. Among the best known are The Gypsy Princess, Countess Mariza and The Circus Princess.
