Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.
Leif Erikson
According to a literal interpretation of Einar Haugen's translation of the two sagas in the book "Voyages to Vinland", Leif was not the first European to discover America: he had heard the story of merchant Bjarni Herjólfsson who claimed to have sighted land to the west of Greenland after having been blown off course. Bjarni reportedly never made landfall there, however. Later, when travelling from Norway to Greenland, Leif was also blown off course, to a land that he did not expect to see, where he found "self-sown wheat fields and grapevines". He next rescued two men who were shipwrecked in this country and went back to Greenland (and Christianised the people there). Consequently, if this is to be trusted, Bjarni Herjólfsson was the first European to see America beyond Greenland, and the two unnamed shipwrecked men were the first people known to Europeans to have made landfall there.
