Hans Pfitzner
Pfitzner's work was appreciated by contemporaries including Richard Strauss and Gustav Mahler, who explicitly described Pfitzner's second string quartet of 1902/03 as a masterpiece. Thomas Mann praised "Palestrina" in a short essay published in October 1917. He co-founded the Hans Pfitzner Association for German Music in 1918. Tensions with Mann, however, developed and the two severed relations by 1926.
