David Andersen is Norway's leading silversmith, established in 1876. The company became world famous for its enamel jewellery in the first half of the 20th century and by the second half was exporting most of its production. Some of the most popular designs were butterflies and leaves. The leaves were designed by Willy Winnaess, and bear his signature.
In the 1950s David-Andersen took the initiative to foster young and innovative designers of modernist 'Scandinavian Design' silver jewellery, with or without enamel and these much saught-after pieces all bear the initials of the designer, preceded by INV (inventor). These include Bjørn Sigurd Østern, Harry Søby, Marianne Berg, Unn Tangerud and Ben David-Andersen as well as Uni David Andersen, the fourth generation of D-As, who established her own workshop in 1959, but also continued to design for the family firm.
