Rosbaud was born in
Graz. As children, he and his brother
Paul Rosbaud performed with their mother, who taught piano. Hans continued studying music at the
Hoch Conservatory in
Frankfurt, under the tutelage of
Bernhard Sekles in composition and
Alfred Hoehn in piano. Rosbaud's first professional post was in
Mainz, starting in 1921, as the music director of the city's new School of Music, which included conducting the municipal symphony concerts. He became the first chief conductor of the Hessischer Rundfunk Symphony Orchestra (later the
hr-Sinfonieorchester or Frankfurt Radio Symphony) of
Frankfurt in 1928. During the 1920s and 1930s, he presented premieres of works by
Arnold Schoenberg and
Béla Bartók. During the
Nazi era, his freedom to present new music was restricted. In 1937, he became the general music director of the city of
Münster. In 1941, Rosbaud took the same position in
Strasbourg, heading the
Orchestre philharmonique. During the war years Rosbaud deliberately kept a low profile, avoiding making any political statements. This was with good reason: his brother Paul was a spy for the
Allies, helping them stay informed, amongst other things, about the Nazi progress towards developing an
atomic bomb. In 1945 he was named music director of the
Munich Philharmonic by United States occupation authorities. In 1948, Rosbaud's contract with the Munich orchestra was allowed to lapse because the city authorities wanted to move the orchestra's repertoire in a conservative direction. That year Rosbaud became the first chief conductor of the
South West German Radio Orchestra in
Baden-Baden, where he remained for the rest of his life. In 1954, he conducted the first performance of Schoenberg's opera
Moses und Aron at 8 days' notice; this performance was issued on a 1957 commercial recording for Philips. He regularly took the SWR Symphony Orchestra to festivals of contemporary music, such as at Donaueschingen. On 6–8 December 1962, he concluded a six-week residency with the
Chicago Symphony Orchestra, leading
Schumann's
Piano Concerto with
Eugene Istomin and
Mahler's
Ninth Symphony. He died less than a month later in
Lugano,
Switzerland on 29 December. == Acclaim ==
