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.
Alonso del Castillo Maldonado
Alonso del Castillo Maldonado (died c. 1540) was one of the first Spanish explorers in the Americas. He was one of the last four survivors of the Pánfilo de Narváez expedition, along with Álvar Núñez Cabeza de Vaca, Andrés Dorantes de Carranza and his African slave Estevanico. They were the first non-natives to travel in the Southwest region of the modern United States. Castillo Maldonado lived with a Native American tribe in Texas in 1527 and 1528.
