Jacob Tostrup

(1806 - 1890)

Jacob Ulrich Holfeldt Tostrup (1806–1890) is regarded as one of Norway’s most celebrated jewellers, silversmiths, and goldsmiths.

Born to infantry captain Nicolai Tostrup, Jacob was the fourth of eight children. Between 1823 and 1828, he lived in Bergen, where he apprenticed under goldsmith Christopher Desinghtun. He later worked in Saint Petersburg for the Imperial Court before settling in Christiania (now Oslo), where he established his own jewellery firm in 1831. His business quickly flourished, allowing him to expand and modernise the workshop. Tostrup’s firm became renowned for its innovative designs, often combining silver with materials such as glass and enamel.

In 1848, he designed the enameled insignia for the newly established Order of St. Olav and was soon entrusted with all of the Order’s insignia production. His exceptional craftsmanship earned him the title of Royal Court Jeweller and the honour of being appointed Knight of the Royal Norwegian Order of St. Olav.

Among his most notable apprentices was David Andersen, who trained under Tostrup from 1859. Andersen would later become one of the most respected Norwegian silversmiths and enamelers, known internationally for his fine craftsmanship and innovative designs.

Jacob’s son, Oluf Tostrup (1842–1882), joined the business at a young age and was among the first to revive traditional Norwegian enamel techniques. He became sole owner of the J. Tostrup company in 1881 but sadly passed away just a year later.

In 1884, Jacob brought his grandson-in-law, Torolf Prytz (1858–1938), into the company. Following Jacob’s death in 1890, Prytz took over the business and became one of the leading figures of the Art Nouveau movement, particularly noted for his filigree work. In 1900, he exhibited at the Exposition Universelle in Paris, where he was awarded a gold medal.

The firm remained in the family and continues to operate to this day, upholding the legacy of innovation and craftsmanship established by its founder.
