No record of apprenticeship or freedom. His name suggests a Swedish origin and possibly arrival in this country already trained as a goldsmith. First appears in London as plateworker, Church Street, Soho, in the Parl. Report 1773. His mark alone was therefore presumably entered in the missing register a little before this. Second mark entered as a plateworker, in partnership with Stephen Gilbert, July 1780. Address: 29 Church Street, St Anne's Soho. Heal records the partnership at this address until 1793.; also, Fogelberg alone till 1800. There is however some confusion with the mark of Alexandra Field which may have led to false assumption to the length of his career. Either alone or with Gilbert his productions show an elegant, restrained classicism, particularly in his speciality of the use of small cameo-like medallions based on the Tassie paste gems popular in England at that time. C.C.Oman has pointed out the parallel use of such decoration in Sweden, suggesting Fogelberg's influence returning to his country of origin, (Apollo, August 1947).
