Stefan-Peter Greiner (born 1966 in Stuttgart) is a German luthier[1][2] residing in Zurich.
In 2013 he moved his workshop from Bonn to London, where he worked with several renowned experts and auction houses.
Since 2018, Greiner has been managing the violin making company W. E. Hill & Sons, London, together with Robert Brewer Young.
His goal was to build instruments that sounded close to a singing voice,[3] with focus on the range from 2000 to 4000 Hz.
During a longstanding partnership with Remagen physicist Heinrich Dünnwald, who had acoustically analyzed over 1300 violins, Greiner felt that he had succeeded in coming close to the sound of centuries-old Guarneri and Stradivari instruments.
