He remained here until his death, and was appointed Music Director there in 1881.
At St. Mary's he introduced the regular free organ concerts, that were so heavily attended that the church often had be closed due to overcrowding! Among his many pupils was Thomas Cantor, Karl Straube was one of his pupils.
He was regarded as a proven expert in the music of Johann Sebastian Bach and outstanding improviser on the organ.
