Johann Christoph Oley (1738 – 1789) was a German organist and composer. 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. At least 77 works for organ solo by his hand survive. The most interesting combine his fondness for strict canon with passages in the more expressive style. Manuscript Mus.ms. 30190 owned by the Staatsbibliothek zu Berlin contains 25 choral preludes by Oley.
Was Gott tut ist Wohlgetan is one of them.
