Johann Christoph Oley was a German organist and composer. There is some evidence that he studied with J.S. Bach for a short time in 1749, but none connecting him with the Thomasschule. In 1755 he became organist of the church in Bernburg, but moved to the church of St Stephan in neighbouring Aschersleben in January 1762 because of its superior organ. To augment his salary he assumed the duties of assistant schoolmaster as well. Source de l'extrait biographique : Wikipedia
