Ernst Welisch

Ernst Welisch (27 February 1875 – 26 March 1941) was an Austrian playwright and theatre director. He is primarily known for the numerous operetta librettos that he wrote for composers such as Leo Fall, Jean Gilbert, Emmerich Kálmán, and Ralph Benatzky. Welisch was born in Vienna, but spent most of his career in Berlin. In the 1930s he returned to Vienna where he died shortly before the premiere of his last work, ''Venedig in Wien''.
