“Jens Witter has created a mammoth work he now calls the World Piano Bible.  With an additional 10,000 entries from its previous mark of 30,000, one way to describe this work is as a ‘Pierce Piano Atlas on steroids.’  In addition to the expected serial numbers, additional information includes factory owners, locations, historical examples of advertising, and current contact information, if available. The work even includes information on museums or other locations of famous examples of piano building history.”

Keith Akins, RPT, Editor of the Piano Technicians Journal


“…that’s incredible, absolutely breathtaking!”

Bruce Clark, Design Engineer for Mason & Hamlin
