Otto Weiss was a gunsmith who worked at Merkel in East Germany before fleeing that country in 1958 for England, where he initially worked at Purdey's. Five years later he relocated to Hamburg, then in West Germany, to work with Gerhard Hartmann as a custom gunsmith. In 1964, he and Hartmann founded the company. Three years later, an associate named Peter Nelson established a second location in England.
