Hans Deinzer (14 January 1934 – 26 February 2020) was a clarinetist and clarinet teacher who taught at the Hochschule für Musik und Theater, Hannover for thirty years, and retired in 1996.
Born in Rothenbruck, Deinzer received his first clarinet lessons at the Städtisches Konservatoriun in Nuremberg between 1949 and 1955. He was until 1962 a student of Rudolf Gall in Munich.
Deinzer was clarinetist at the Nürnberger Symphoniker and at the Sinfonieorchester des Norddeutschen Rundfunks in Hamburg.
He was one of the first clarinetists to professionally adopt the use of rubber mouthpieces, and also was a champion of historical instruments and playing. He recorded two versions of the Mozart Clarinet Concerto using a reconstructed historical boxwood clarinet and has premiered several important works, including Pierre Boulez's "Domaines" —which was written for him— and Henri Pousseur's Madrigal I.
He is a two-time winner of the Grand Prix du Disque.
