Johann Christian Friedrich Hæffner

Johann Christian Friedrich Hæffner (2 March 1759 in Oberschönau – 28 May 1833 in Uppsala) was a German-born Swedish composer.

He moved to Stockholm, Sweden in 1781 at the invitation of the German congregation there (Tyska kyrkan) to assume the position of organist, which he held until 1793.

Since King Gustaf IV Adolf closed the Royal Opera (and its orchestra) in 1807, Hæffner moved to Uppsala, where in 1808 he was appointed Director musices of the university and simultaneously was employed as organist of the cathedral.
