Georg Caspar Wecker (baptized 2 April 1632 – 20 April 1695) was a German Baroque organist and composer. A minor composer of the Nuremberg school, Wecker is now best remembered as one of Johann Pachelbel's first teachers. An acclaimed teacher, Wecker was, along with Heinrich Schwemmer, an important link in the 17th century Nuremberg teacher-pupil tradition. Himself a pupil of Kindermann, he taught keyboard instruments and composition to Johann Krieger and Johann Pachelbel. Few of his works survive to this day: several cantatas, some 40 songs and 4 keyboard fugues.
