In Munich, brothers Joseph and Anton Hemmerle take over an established goldsmiths' company in 1893 specialising in medals and orders, whose clients include the Bavarian Royal family. The brothers bring their own style and ideas to the business, renamed Hemmerle.
Hemmerle is appointed "Purveyor to the Court" by Luitpold, Prince Regent of Bavaria. They become renowned for the "bejewelled fantasies" they create for Ludwig III of Bavaria, the Bavarian government and the great families of the German nobility.
