Johann Carl Christian Fischer (1733–1800) was a German composer. Employed as a music copyist and theatre director for the Duke of Mecklenburg-Schwerin at Ludwigslust, Fischer is now credited with the unique Symphony with Eight Obbligato Timpani, formerly attributed to Johann Wilhelm Hertel, court composer at Schwerin.[1] He spent some time in London, one of the most musical cities of Europe. While there he was active as a performer, composer, and a teacher. Among his students was composer and oboist Charles J. Suck. An etching/aquatint A Sunday concert by Charles Loraine Smith, published 4 June 1782,[2] shows a distinguished musical group gathered round a harpsichord, with Charles Burney among them. Mozart composed a set of Twelve Variations in C on a Menuett of Johann Christian Fischer (K.179 [189a]).
