Answer:
It is believed to be Columbus, but it is actually Viking Explorers.

In 1492, Columbus sailed the blue; and was, for a time, considered to be the first European to set foot on the Americas. And then came evidence that Viking explorers, led by Leif Ericson, had beaten him to it by some five centuries.
