done exceptionally well" during the war and that his brothers had been "fanatical" Nazis; but British authorities "found no fault" with Jochum, arguing that he had never been a member of the Nazi party, SS or Sturmabteilung, had remained a "convinced Roman Catholic," and had "not compromised his artistic integrity." It took until 1948 before the American authorities determined that they could find no evidence of his joining any Nazi organizations. Jochum continued to serve at Hamburg until 1949, then left when the newly reconstituted Bayerischer Rundfunk appointed him the founding music director of its new orchestra, the Bavarian Radio Symphony Orchestra. To build the orchestra, Jochum "recruited highly qualified musicians," including the Koeckert Quartet as the "nucleus of the strings". Jochum remained music director of the orchestra until 1961; with it, he made numerous recordings, mostly for Deutsche Grammophon. Jochum was also a regular guest conductor of the Concertgebouw Orchestra, Amsterdam, and served as the orchestra's 'first conductor' () from 1941–1943, during the chief conductorship of Willem Mengelberg. From 1961 to 1963, Jochum was joint chief conductor of the Concertgebouw Orchestra alongside Bernard Haitink. He conducted frequently in London, with the London Philharmonic Orchestra and the London Symphony Orchestra. In 1975, the LSO appointed him conductor laureate, a position he held until 1978. Jochum served as principal conductor of the Bamberg Symphony from 1969-1973. He later worked regularly with the Staatskapelle Dresden, with which he recorded the complete symphonies of Bruckner and "London" symphonies of Joseph Haydn (which latter he also recorded with the London Philharmonic). He appeared regularly at the Salzburg Festival. He also, in 1953–54 and 1971, conducted at the Bayreuth Festspielhaus; he made his debut conducting Tristan und Isolde. He led the world premieres of various works, including the Concerto for Strings by Boris Blacher, the Concerte per il principe Eugenio by Alberto Bruno Tedeschi, the Suite Française by Werner Egk, the Tanz-Rondo by Gottfried von Einem, and the Symphony No. 6 by Karl Amadeus Hartmann. He was a regular recording artist, from his first records in 1932. In the stereo LP era, he recorded mainly for Deutsche Grammophon. His DG cycle of the symphonies of Anton Bruckner, split between the Berlin Philharmonic and Bavarian Radio Symphony Orchestra, has remained in the record catalogs ever since its first issue in the 1960s. This cycle and a later Jochum Bruckner cycle, with the Staatskapelle Dresden for EMI,
