(b Arolsen, bapt. 15 Feb. 1740; d Potsdam, early 1777). German bassoonist and composer. He was a member of the orchestra at Zweibrücken in 1762, becoming its Konzertmeister in 1769. In 1770 he travelled to Paris with Duke Christian IV of Zweibrücken, but two years he later left the duke's service and made an extended tour to London, where he played the bassoon in J. C. Bach's subscription concerts. In 1773 he joined the musical establishment of Prince Friedrich Wilhelm (later King of Prussia). According to Burney, Eichner was an excellent bassoonist; he was also a composer of merit, writing several symphonies (which show a highly developed conception of sonata form) and concertos.
