Berlin Deutsche Oper Chorus

The company's history goes back to the Deutsches Opernhaus built by the then independent city of Charlottenburg—the "richest town of Prussia"—according to plans designed by Heinrich Seeling from 1911. It opened on November 7, 1912 with a performance of Beethoven's Fidelio, conducted by Ignatz Waghalter. In 1925, after the incorporation of Charlottenburg by the 1920 Greater Berlin Act, the name of the resident building was changed to Städtische Oper (Municipal Opera). wikipedia
