Johann Gottfried Eckard (Eckhardt) (21 January 1735 – 24 July 1809) was a German pianist and composer. Eckard was born in Augsburg. In his youth he became a professional copper engraver and acquired his musical training in his leisure time, mainly from C.P.E. Bach's Versuch über die wahre Art das Clavier zu spielen and its six ‘Probesonaten’. In 1758 the piano and organ manufacturer Johann Andreas Stein took him to Paris, where he lived for the rest of his life. At first he supported himself by painting miniatures, a craft in which he apparently possessed considerable skill. He practised the piano in his free time and quickly developed a great facility. Many successful concerts soon gained him fame and numerous students.
