F. Jacob Kaeser began working at Zuckermann Harpsichords in 1978 under the tutelage of David Way and Wolfgang Zuckermann. He began by mastering the art of milling harpsichord parts, carefully choosing the right plank of wood for the necessary application, and cutting to exacting standards.  Soon after he graduated to the assembly bench.  This was a fortuitous time in the history of 20th century harpsichord-making, as David Way began building instruments in the manner of the "old masters."  Beginning with the use of solid planks of lumber instead of plywood, and utilizing the original joinery techniques, the instruments transformed the early music community.   As the Zuckermann shop developed from a research and development shop to  a production facility, Mr. Kaeser, along with others, developed the jigs and tooling to produce accurate harpsichord kits for the public.  The manuals for these kits, written by David Way and Michael Smith, are still today the finest examples of literature pertaining to the workings and temperaments of the harpsichord. The final three years in the employ of Zuckermann harpsichords was spent toiling with Mr. Way designing new instruments based on historic examples.

In 1992 Mr. Kaeser started his own venture, Kaeser Instruments.  Utilizing his experience, he produces cases, keyboards, and action assemblies for professional builders and restorers.  Many professional instrument makers, lacking space for production tools, have turned to Kaeser Instruments for production of their designs.
