The first silversmith of the honourable Weishaupt dynasty was Anton Weishaupt. He became a partner in the Leismiller company in 1801. The Leismiller family had owned the Licence to practice as a silversmith from the Munich Magistrate's Court since 1692. In 1802 Anton took over the business after the last of Leismillers was retired and continued to work with their original licences.
