Cornelius Heinrich Dretzel

Cornelius Heinrich Dretzel (18 September 1697 (bapt.) – 7 May 1775) was a German organist and composer. He was born in Nuremberg, where he appears to have spent his whole life in various organists' posts, including: St. Egidien, Nuremberg 1719–1743 St. Lorenz, Nuremberg 1743–1764 St. Sebaldus Church, Nuremberg 1764–1775

He may have studied with J. S. Bach in Weimar (1716–1717), and his compositions reveal points of contact with Bach. They include a concerto for harpsichord solo, perhaps modelled on the Italian Concerto. A variant of the slow movement of his solo concerto Divertimento armonico was once thought to be by Bach: it was published as a prelude by Bach in the 19th-century Bach-Gesellschaft edition, and listed in the first edition of the Bach-Werke-Verzeichnis (BWV) as the first movement of BWV 897 (BWV 897/1).
