Hans Hinrich Zielche (baptized February 22, 1741 in Plön; † June 13, 1802 in Copenhagen) was a German flautist and composer.Hans Hinrich Zielche was the son of a father of the same name (* 1695/96; † November 17, 1783 in Plön) and his wife Anna Elisabeth, née Sahr, who died in 1787. From 1744 his father was an innkeeper in Plön and a lackey and flautist at the Plöner Hof and probably gave his son his first flute lessons. Duke Friedrich Carl, who had a court orchestra, financed him six months of composition lessons with Georg Philipp Telemann in Hamburg in 1757. At the same time he also learned from Friedrich Hartmann Graf, with whom he later arranged and performed.
