With my retirement 2016 I transfered my knowledge to my successors:
- The construction of the Louis XVI-Harp is now taken over by Dario Pontiggia, Milano.
- The construction of the Small Harp and Gothic Harp is now taken over by Peter Demmerle, Schaffhausen.
- The restoration of early harps will be taken over by Peter Demmerle, Schaffhausen and Dario Pontiggia, Milano.
