Georg Caspar Wecker (baptized April 2, 1632 in Nuremberg; † April 20, 1695 ibid) was a German composer and organist of the Baroque period.
Wecker's parents were Agnes, née Schneider and Johann Wecker, a gold spinner by trade who had received at least some musical training. Georg Caspar Wecker learned the musical basics from him.
The Nuremberg composer and organist Johann Erasmus Kindermann was Wecker's next teacher, with whom he learned so much that he was allowed to play the organ in Nuremberg churches at the age of 16.
Wecker was married since 1658 to Anna Maria Löhner with whom he had nine children.
Commencing in 1651, Wecker was organist at Nuremberg churches throughout his life:
from 1651 at the St. Walburga Church and from 1658 as successor of Paul Hainlein at the St.-Ägidien-Kirche. When Hainlein died in 1686, Wecker again became his successor as organist at the important parish church of St. Sebald. He held this position until the end of his life and was succeeded by his pupil Johann Pachelbel.
Johann Krieger was also one of his pupils. Wecker's successor at St. Ägidien was Albrecht Martin Lunßdörffer.
