Through the Bauhaus masters László Moholy-Nagy and Oskar Schlemmer, the Kroll Opera had connections to the Bauhaus Dessau. But there was also an interesting connection to Kassel. Ewald Dülberg, a former professor at the Kassel Art Academy, and Teo Otto, a fellow student and friend of Arnold Bode, had also found work here. Both had come to Berlin in 1927 after a short period of teaching at the Staatliche Bauhochschule Weimar, the successor to the Bauhaus in Weimar.
Bode must have been connected to Berlin's avant-garde theater scene, which had also taken up Bauhaus ideas, through his former teacher Ewald Dülberg, whom he greatly appreciated, and his friend Otto . His wife Marlou recalled many years later: "We were young, only just married, and had an insanely large number of friends, many Jews among them, artists and writers, the whole circle around Brecht, Teo Otto.”
But soon the Krolloper was closed. Right-wing parties applied to end the house’s "cultural Bolshevism." The last performance took place on July 3, 1931.
