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.
Italians
Italian explorers and navigators in the 15th and 16th centuries left a perennial mark on human history with the modern "discovery of America", due to Christopher Columbus. In addition, the name of the American continents derives from the geographer Amerigo Vespucci's first name. Also noted, is explorer Marco Polo who travelled extensively throughout the eastern world recording his travels.
