Karl Treumann

Matthias Karl Ludwig Treumann (27 July 1823 – 18 April 1877) was an Austrian actor, operetta singer (tenor), theatre director and writer.

In order to avoid conscription for military service in Hamburg, he joined a touring theatre troupe in Transylvania.

The triumphal success of Offenbach's Orpheus in the Underworld, in his adaptation with Nestroy as Jupiter laid the foundation for the development of the Viennese operetta.

In order to escape the high lease of the new owners of the Carltheater, at which Nestroy had already failed as director, in 1860 Treumann founded the Theater am Franz-Josefs-Kai [de] ("Kaitheater" or "Treumann-Theater"), which he managed until its destruction by a fire in 1863.

[citation needed] Treumann undertook many tours to Hamburg, Berlin, Prague, Lemberg, Budapest and Brno, and in this way acquired a significant fortune.
