Niels Horrebow (1712-1760) was a well-respected Danish citizen—a high court judge, no less—but he had mishandled finances and faced hard times. He saved himself somehow when he was sent to Iceland by the Royal Danish Academy of Sciences, sailing in 1749. In 1752 he published a book of his experiences, Tilforladelige Efterretninger om Island. The book was accompanied with a map of Iceland, based on Thomas Hans Henrik Knoff’s measurements and maps. This ushered in changes in the outdated and sometimes wild ways in which Iceland was being shown on maps at the time.
