Helge Ingstad was originally a lawyer by profession, but, ever an outdoorsman, sold his successful law practice in Levanger and went to Canada's Northwest Territories as a trapper in 1926. After returning to Norway, he wrote the bestselling The Land of Feast and Famine (Knopf, 1933).
Ingstad became governor of Erik the Red's Land, from 1932 to 1933, when Norway annexed that eastern part of Greenland. The International Court of Justice in The Hague decided that the lands belonged to Denmark, and so the official Norwegian presence had to end.
(note that Ingstad's wife's name is misspelled (twice, differently) in this otherwise well-written obituary)
