Jacob Ulrich Holfeldt Tostrup (1 July 1806 – 31 January 1890)
He started as a goldsmith apprentice in Bergen between 1823 and 1828. He then had short stays in St. Petersburg and Copenhagen. He received his journeyman's certificate in 1828. He then moved to Christiania (now Oslo) and acquired burghership. In 1832, he founded the jewelers firm J. Tostrup, gradually expanding his business with more production equipment and better localities. Tostrup held several positions in the goldsmith's guild and artisan associations. His firm made the original enameled insignia for the Order of St. Olav, when the order was established in 1848 and later in 1883 it was put in charge of the whole production. J. Tostrup received the title royal court jeweler, and Jacob Tostrup received the Norwegian King's Medal of Merit in gold (Kongens fortjenstmedalje) and was appointed a Knight of the Royal Norwegian Order of St. Olav for his work as a goldsmith. Upon his death, his Granddaughter's husband, Torolf Prytz became owner of the store. Torolf Prytz' son, and Jacob Tostrup's great-grandson, Jakob Tostrup Prytz (1886–1962) also became a notable jewelry designer and goldsmith.
