Anton Stadler

Anton Paul Stadler (28 June 1753, in Bruck an der Leitha – 15 June 1812, in Vienna) was an Austrian clarinet and basset horn player for whom Wolfgang Amadeus Mozart wrote, amongst others, both his Clarinet Quintet (K 581) and Clarinet Concerto (K 622). Stadler's name is inextricably linked to Mozart's compositions for these two instruments. Provided by Wikipedia
