Herman Didrich Janson was a rough figure in the mountains around 1800.

Janson’s father was a Dutch immigrant who settled down as a merchant in Bergen. As a young boy, Herman was sent to sea. After graduating, he became a skipper and sailed for a councilor and merchant Danckert D. Krohn .

In 1786, Janson raised the sea and established his own merchant company. He had lost his first wife already in 1781 and had a good eye on Danckert Krohn’s brother-in-law Christiane Benedicte. But the dad’s father considered such a connection as a mesallian until Jansen with Danckert Krohn’s help was appointed to the court agent in 1785 to pay the king 800 riksdaler. Shortly thereafter the wedding stood, and the groom changed the name of Jansen to Janson.

Handelshuset Herman D. Janson got a good start when the childless Danckert D. Krohn handed him over to his house in Strandgaten and most of his shops in 1786 and his father-in-law the following year transferred some of his business relations to him. Janson developed his young trading house with great skill. The main business was the export of dried fish and cutfish to a number of countries and imports of salt, wine and colonial products.

In 1788, Janson bought his first ship, Frigate Test, which was put into whaling and cob catching in Greenland, a business that other merchants in town had started a couple of years earlier and as Janson continued until around 1806.

When the trade in Iceland was released in 1787, Janson was a driving force behind the creation of a partnership to trade there. Together with FL Konow, G. Cappe and GF Vedeler, he established trading stations in Isafjörður and Bolungavík, and significantly exported it with grain, timber, iron, tobacco and beverages from Bergen and with dried fish, salted fish and wool in return. The business was driven until 1796.

From 1792, Janson also received interests in several larger vessels, and in 1802 his son Henrich was taken up in the company, which changed its name to Herman D. Janson & Søn. At that time, the trading house also began to engage in factory operations, and in 1810 the construction of a paper mill began in Årstad, which a few years later employed 12 people. In 1812, Janson retired from the company, and the son became sole proprietor.

During the napoleon wars of 1807-14, the company engaged in crash, it also participated in the grain mining at Arkhangelsk 1808-09 and was among the Bergen trade houses seeking to sign insurance for vessels sailing in Spain’s salt trade. The company participated in the trade show’s protests against customs duties on export goods and the buyer’s citizens’ application to remedy the shortage of money in the distress years. It was also one of the 13 trading houses in Bergen, which was invited to a meeting in 1813 for the establishment of a private loan and discount office for Norway.

Janson lived statically in the Danckertsen house in Strandgaten 28 (destroyed in the city fire 1916), built on the walls of the medieval Jonskloster walls. In 1796, he bought the property Damsgård in Laksevåg, and the following year he made a major rebuilding of the main house, which became the venue for the city’s foremost merchants and officials. The family lived with Damsgård until 1983, when the farm was bought by the municipality of Bergen and transferred to the Vestlandske Kunstindustrimuseum. The main house is protected.

Janson was a member of the Useful Company, boarded for the Bergen Real School and was one of the largest contributors to the new Norwegian university.

He left only one son of first marriage and one daughter of the other. In his third marriage, he received the hand of the great Svanøy estate in Nordfjord in 1791, which he disposed of in 1802.
