The orchestra was founded in 1952 as the Berliner Sinfonie-Orchester (Berlin Symphony Orchestra) in what was then East Berlin, as a rival ensemble to the Berlin Philharmonic Orchestra based in West Berlin. The first chief conductor was Hermann Hildebrandt. In 1974, the Berlin Sinfonietta was founded to serve as the sister chamber orchestra of the Berliner Sinfonie-Orchester. After German reunification in 1989, the orchestra was threatened with dissolution, but subscriber action maintained the ensemble. The orchestra acquired its current name in 2006. (This orchestra is separate from the West-Berlin based Berliner Symphoniker, founded in 1967.) The Konzerthausorchester Berlin currently has, as its sister chamber orchestra, the Konzerthaus Kammerorchester. wikipedia
