About Helge Ingstad:
Helge Marcus Ingstad was a Norwegian explorer. After mapping some Norse settlements, Ingstad and his wife Anne Stine, an archaeologist, in 1960 found remnants of a Viking settlement in L'Anse aux Meadows in the Province of Newfoundland in Canada. With that they were the first to prove conclusively that the Greenlandic Norsemen had found a way across the Atlantic Ocean to North America, roughly 500 years before Christopher Columbus and John Cabot. He also thought that the mysterious disappearance of the Greenland Viking settlement in the 14/15th century could be explained by their emigration to North America.
