Hans Ulrich Mølmann

Hans Ulrich Mølmann was a Norwegian entrepreneur born in Trondheim. He studied at the University of Copenhagen. In 1754 he was granted a royal privilege to establish a sugar refinery, Trondheim's first industrial company and the oldest factory building in Norway. The building became known as Sukkerhuset and was the largest building in town when first constructed.

Mølmann’s royal privilege to establish this factory to supply sugar and syrup to the region was a part of large system of commerce between north Europe and the West Indies. The West Indies-Guinean Trading Company in Copenhagen arranged for the transportation of slaves from West Africa to the sugar plantations in the West Indies, returning with cargoes of unrefined sugar for the Danish-Norwegian refineries.

Hans Ulrich Mølmann was also involved in mining, was partner in Røros Copper Works, and in 1757 he took up operations at Mostad Marken ironworks.
