Dominikus Debler 1757-1836 is the first traceable Debler name involved in jewelry making which seemed to pass from generation to generation until Hermann Debler who birthed a son Friedrich.  Freidrich Hans Debler can be traced to Gmünd, Germany.  Freidrich learned the business from Hermann at first who specialized in painting watch dials and crafting enameled watch diamonds before working for the Münstermann company in Düsseldorf, Germany.  Eventually he started out on his own in 1960 where he crafted many different pieces.
