Albert Mangelsdorff (September 5, 1928 in Frankfurt, Germany – July 25, 2005 in Frankfurt) was one of the most accredited and innovative trombonists of modern jazz who became famous for his use of multiphonics. 　　Mangelsdorff was born in Frankfurt. He was given violin lessons as a child and was self-taught on guitar in addition to knowing trombone. His brother, alto saxophonist Emil Mangelsdorff, introduced him to jazz during the Nazi period (a time when it was forbidden in Germany). After the war Mangelsdorff worked as a guitarist and took up trombone in 1948. 　　Trombonist Albert Mangelsdorff pioneered the art of jazz polyphonics, introducing to the avant-garde the symphonic tradition of playing multiple notes simultaneously. Born in Frankfurt, Germany, on September 5, 1928, Mangelsdorff grew up enthralled by jazz, devouring his older brother Emils record collection. His uncle, a professional violinist, gave him music lessons as a teen, but the rise of the Third Reich forced him to keep his passion for jazz in check.
