What was the nationality of the late composer Emmerich Kálmán?

Emmerich Kálmán (24 October 1882 – 30 October 1953) was a Hungarian composer of operettas and a prominent figure in the development of Viennese operetta in the 20th century.

Among his most popular works are "Die Csárdásfürstin" (1915) and "Gräfin Mariza" (1924). Influences on his compositional style include Hungarian folk music (such as the "csárdás"), the Viennese style of precursors such as Johann Strauss II and Franz Lehár, and, in his later works, American jazz. As a result of the Anschluss, Kálmán and his family fled to Paris and then to the United States. He eventually returned to Europe in 1949 and died in Paris in 1953.

The popularity of his humorous cabaret songs led him towards the composition of operettas. His first great success was "Tatárjárás – Ein Herbstmanöver" in German, meaning Autumn maneuver, although the English title is "The Gay Hussars", which was first staged at the Lustspieltheater in Budapest, on 22 February 1908. Thereafter he moved to Vienna, where he achieved worldwide fame through his operettas "Der Zigeunerprimas", "Die Csárdásfürstin", "Gräfin Mariza" and "Die Zirkusprinzessin".
