Joseph Küffner (Kueffner) (March 31, 1776 Würzburg ? September 9, 1856 Würzburg) was a German musician and composer. He was a violinist with the Würzburg court orchestra, and was later, when Würzburg became part of Bavaria (1802), assigned to take charge of military music. At this point he became bandmaster with a Bavarian Army regiment.
A quintet of Küffner's for clarinet and strings was once attributed to Carl Maria von Weber, and is still recorded in collections of Weber's music. He composed seven symphonies among other works. His output also contains a substantial quantity of music for classical guitar (some of it still published as of 2008 and some newly reprinted). (Hide extended text)...(Read all) Source : Wikipedia
