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 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).
