Leif Erikson, also known as Leif the Lucky (c. 970s – c. 1018 to 1025), was a Norse explorer who is thought to have been the first European to set foot on continental America, approximately half a millennium before Christopher Columbus. According to the sagas of Icelanders, he established a Norse settlement at Vinland, which is usually interpreted as being coastal North America. https://en.wikipedia.org/wiki/Leif_Erikson
