The Berliner Ensemble is a German theatre company established by playwright Bertolt Brecht and his wife, Helene Weigel in January 1949 in East Berlin. In the time after Brecht's exile, the company first worked at Wolfgang Langhoff's Deutsches Theater and in 1954 moved to the Theater am Schiffbauerdamm, built in 1892, that was open for the 1928 premiere of The Threepenny Opera (Die Dreigroschenoper).
