Otto Klemperer
He recommended him for the job of conductor at the German Opera in Prague. He soon got jobs in other places: Hamburg, Barmen, Strasbourg, Cologne and Wiesbaden. He was offered a job at the Berlin Staatsoper, but he did not want it because he thought he would not be able to do things there the way he wanted. However, four years later, in 1927, he took a job with a special branch of the Staatsoper which had been started in order to perform new music in modern (non-traditional) performances. They played in the Kroll Theatre. Klemperer became very famous for the performances that he conducted there.
