About Benjamin Wegner
Lived 1795 – 1864 (aged 69). Benjamin Wegner was a German and Norwegian industrialist, merchant and timber merchant, known for Industrialist.
Jacob Benjamin Wegner (21 February 1795 – 9 June 1864) was a Norwegian business magnate. He was one of the country's leading mining magnates as the director-general and co-owner of Blaafarveværket, and also had significant interests in other mining and timber companies.
Born in Königsberg, East Prussia, he moved to London in 1819 and to Berlin in 1820, where he established an independent business as an agent in the British timber and grain trade, as a close associate of the London firm Isaac Solly and Sons. In 1820 and 1821, he also facilitated one of history's largest art sales on behalf of his close associate Edward Solly. In 1822, he settled in Norway, after he had bought Blaafarveværket (The Blue-Colour Works) on behalf of a consortium led by the Berlin banker Wilhelm Christian Benecke. From 1822 to 1849, he was Director General and one of two owners of Blaafarveværket. Under his leadership the company became Norway's largest mining company and largest and most successful industrial enterprise in the first half of the 19th century overall, and by far the world's largest producer of cobalt blue. He was also the owner of Frogner Manor, the largest co-owner of the Hafslund estate, a co-owner of the Hassel Iron Works and a co-owner of the timber firm Juel, Wegner & Co. Most of his business activities, both in the timber, grain and cobalt segments, focused heavily on export to England, where he spent much time throughout his life.
He served as consul general to Norway of the sovereign city-republics of Hamburg, Lübeck and Bremen, and as vice consul of the Kingdom of Portugal. He was married to the philanthropist Henriette Seyler (1805–75), a member of the Berenberg banking dynasty of Hamburg and briefly a co-owner of Berenberg Bank; she was the youngest daughter of Berenberg Bank's long-time head and co-owner L.E. Seyler, and a granddaughter of the Swiss-born banker and theatre principal Abel Seyler and of the Hamburg bankers Johann Hinrich Gossler and Elisabeth Berenberg.

Jacob Benjamin Wegner, who went by the name of Benjamin, was born in Königsberg, an important port city on the coast of the Baltic Sea. He was the son of Police Commissioner in Königsberg Johann Jacob Wegner (ca. 1757–1797) and Regina Dorothea Harder (1770–1813). His father had previously been married to Regina Dorothea's sister Anna Christina Harder (1765–1791). His father died on 12 January 1797, and his mother remarried to shipbuilder Philipp Gutzeit in 1798. He had a brother, Friedrich Salomon Wegner (born 1793), and several half-siblings from his parents' two other marriages. Philipp Gutzeit was a younger brother of ship's captain and shipbuilder Benjamin Gutzeit, who was the father of the industrialist Wilhelm Gutzeit, the founder of one of Stora Enso's two principal predecessor companies.
Benjamin Wegner received a solid commercial education and joined a leading Königsberg firm as an apprentice.
British timber and grain trade
Around 1820, he moved to Berlin where he established an independent business as an agent in the British timber trade and grain trade, i.e. in large-scale export of timber and grain from the Baltic region to England. He was an agent and close associate of the London firm Isaac Solly and Sons and of the Berlin firm Gebrüder Benecke and its head Wilhelm Christian Benecke, and spent much time in London.
Solly's art sale On behalf of his friend and close business associate Edward Solly, he also negotiated the agreement to sell Solly's unprecedented art collection of around 3,000 paintings—mainly Italian Trecento and Quattrocento paintings and Early Netherlandish paintings—to the Prussian king Frederick William III in 1821, of which 677 paintings formed the core of the collection of the new Gemäldegalerie. The negotiations were conducted by Wegner and Benecke on Solly's behalf, partly with Prince Hardenberg and partly with King Frederick William III personally.
As a consequence of the economic crisis following the revolutions of 1848 and also of the invention of the synthetic ultramarine colour, Modums Blaafarveværk went bankrupt in 1849.
Other enterprises and activities
Together with Benecke, Wegner owned the Hassel Iron Works from 1835 to 1854, each with half of the shares. He was also a co-owner, eventually the largest co-owner, of the major estate Hafslund with large forests in eastern Norway and the country's largest sawmill, from 1835 to 1864. His co-owners included Benecke and Herman Wedel Jarlsberg, and subsequently Thorvald Meyer and Westye Egeberg. In 1856, he co-founded the timber firm Juel, Wegner & Co. with Iver Albert Juel.
In 1836, he bought Frogner Manor, where he lived with his family until 1849. The family then sold Frogner Manor and moved to Christiania (now the inner city). Wegner however retained a part of the Frogner property, Frognerseteren with a part of the Nordmarka forests, until his death. Frogner Manor is today best known as the site of Frogner Park.
Consular roles
Wegner was appointed as Vice-Consul in Christiania for the Kingdom of Portugal in 1836, as Portugal's most senior representative in Norway. He became Consul in Christiania for the sovereign city-state of Hamburg – where his wife's family served in the government – in 1842 and was promoted to Hamburg's Consul-General for the Kingdom of Norway in 1844. He became Consul in Christiania for the city-state of Lübeck in 1843 and was promoted to Consul-General of Lübeck in 1861. He became Consul-General for Norway of the city-state of Bremen in 1859. He held these four consular offices until his death.
Death He died at his country home, Dronninghavn, at Ladegaardsøen (Bygdøy), on 9 June 1864.
