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.
Naming of the Americas
The earliest known use of the name "America" dates to April 25, 1507, where it was applied to what is now known as South America. It appears on a small globe map with twelve time zones, together with the largest wall map made to date, both created by the German cartographer Martin Waldseemüller in Saint-Dié-des-Vosges in France. These were the first maps to show the Americas as a land mass separate from Asia. An accompanying book, "Cosmographiae Introductio", anonymous but apparently written by Waldseemüller's collaborator Matthias Ringmann, states, "I do not see what right any one would have to object to calling this part [that is, the South American mainland], after Americus who discovered it and who is a man of intelligence, Amerigen, that is, the Land of Americus, or America: since both Europa and Asia got their names from women".
