The first one, Jakob Pies (b. 1860 in Dorweiler), had “married into” Kappel in 1895. His son Robert Pies (1902–1973), was the last genuine "Knochenflicker" in Kappel. Both were farmers who, in the tradition of the Hunsrück Pies family, also practised chiropractic, focusing especially on setting joints right again. The patients came from afar to undergo treatment. From the sometimes painful treatment supposedly came the German word "piesacken" (a verb meaning “badger”), but this is likely folk etymology. The Pies family's history is documented at the "Vorderhunsrückmuseum" in Dommershausen.
