Karl Amadeus Hartmann (August 2, 1905 - December 5, 1963) was a German composer. Arguably, he is the greatest German symphonist of the 20th century.
Hartmann was a pupil of Anton Webern. His work was prohibited in the Nazi era. He continued to live in Germany during that time and composed for the drawer. After the war he finished a number of fine works, most notably eight symphonies.
