Hans Pfitzner (1869--1949) was born in Moscow of German parents. His father was a professional violinist and he received violin lessons from his father. Later he studied piano and composition at the Hoch Conservatory in Frankfurt. He enjoyed a long career as a conductor and teacher. His music was held in high regard by contemporaries such as Richard Strauss and Gustav Mahler. Pfitzner was an avowed opponent of the Second Vienna School with its serialism and atonal music. Instead, he sought new paths for traditional tonality. He composed in nearly every genre and is best known for his operas. He did not ignore chamber music, writing a number of string quartets, a piano trio and a piano quintet.
