The NDR Elbphilharmonie Orchestra (German: Orchester) is one of the symphony orchestras of Norddeutscher Rundfunk (NDR), or North German Broadcasting. It is based at the Elbphilharmonie in Hamburg, Germany, taking its name in 2016 from the building, which opened officially in January 2017. Earlier the ensemble was called the NDR Symphony Orchestra (German: Sinfonieorchester des Norddeutschen Rundfunks) or, less often, the North German Radio Symphony Orchestra.
It was founded by British occupation authorities after World War II as part of Radio Hamburg (NWDR), which was the only radio station in what would become West Germany not destroyed during the war. The first musicians came mostly from the ranks of the old Nazi-controlled Großes Rundfunkorchester des Reichssenders Hamburg. Hans Schmidt-Isserstedt, who was living near Hamburg, was given the task of assembling the members, something he accomplished over a period of six months. The orchestra gave its first concert in November 1945 under his baton, with Yehudi Menuhin as soloist.
