His father died in 1769 and from then on he also managed the family fur business, though he still managed concert tours of Germany in the early 1770s, then in other places in Europe in the 1780s and 1790s. On 15 April 1789 he entered an organ competition with Wolfgang Amadeus Mozart in Dresden during Mozart's Berlin journey.
