The String Quartet in D major, K. 499, was written in 1786 in Vienna by Wolfgang Amadeus Mozart. It was published by – if not indeed written for – his friend Franz Anton Hoffmeister. Because of this, the quartet has acquired the nickname Hoffmeister. Hoffmeister had started issuing a series of chamber-music publications in 1785, including Mozart's K. 499 as well as Joseph Haydn's Op. 42.
