Half a millennium before Columbus “discovered” America, those Viking feet may have been the first European ones to ever have touched North American soil. Exploration was a family business for the expedition's leader, Leif Eriksson (variations of his last name include Erickson, Ericson, Erikson, Ericsson and Eiriksson).Five hundred years before Columbus, a daring band of Vikings led by Leif Eriksson set foot in North America and established a settlement. And long before that, some scholars say, the Americas seem to have been visited by seafaring travelers from China, and possibly by visitors from Africa and even Ice Age Europe.By 1502, the Florentine merchant and explorer Amerigo Vespucci had figured out that Columbus was wrong, and word of a New World had spread throughout Europe. America was later named for Vespucci. And, as researchers now recognize, neither man was actually the first to discover the Americas.^-^
