In order that his wife could continue her business, Freytag entered the guild of innkeepers,[1] and received the "small citizenship" (kleine Bürgerrecht) of the city of Groningen.
When Snitger died in 1799 Freytag took over the organ-building workshop, and led north-Dutch organ building into a new era of productivity.
In the 1800's, Freytag built a number of single-manual chamber organs with six ranks and no pedal (for example in Lellens [nl], Anloo and Doesburg).
Herman Eberhard also worked in Germany, and carried out restorations of Hinsz's organs in Leer and Weener.
Herman Eberhard's son, Willem Fredrik Freytag (1825–1861) was expected to continue the family business, but died before his father.
