 In Berlin Busoni was at the heart of the musical world of the Weimar Republic. His works, including his operas, were regularly programmed. He continued to perform whilst his health allowed it; problems of hyperinflation in Germany meant that he needed to undertake tours to England. His last appearance as a pianist was in Berlin in May 1922, playing Beethoven's Emperor Concerto. Amongst his composition pupils in Berlin were Kurt Weill, Wladimir Vogel and Robert Blum, and he also during these last years had contact with Edgard Varèse, Igor Stravinsky, Hermann Scherchen and others.
