Helge Marcus Ingstad (30 December 1899 – 29 March 2001) 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.
