Klaus Hermann Wilhelm Tennstedt was a German conductor from Merseburg. Known for his interpretation of the Austro-German repertoire, especially his sympathetic approaches towards Gustav Mahler, Tennstedt is widely considered one of the greatest and most influential conductors of the late 20th century. He worked with the Swedish Radio Symphony Orchestra, the NDR Symphony Orchestra, and other highly regarded ensembles such as the Berlin Philharmonic Orchestra, and most notably the London Philharmonic Orchestra, with which he was closely associated and recorded many of his celebrated recordings under the EMI label, including a cycle of Mahler's 10 symphonies.
