Clarinet in F
August T. Knochenhauer (born Potsdam 15 April 1796) trained at Griesling & Schlott in Berlin and also worked in Dresden. He was foreman for the Weisse firm in Berlin in 1819. In 1826, Knochenhauer established his own firm in Berlin and was appointed Court maker in 1841. In the same year he got an appointment as Hofinstrumentenmacher ‘on account of his excellent flutes, clarinets’. The Prussian eagle in his stamp suggests that these instruments were made after this date. G.A.R. might be the Garde du Corps of the King of Prussia and 1856 the year when the instrument was purchased for the army.
