The correct answer is Ferdinand Magellan.
He was born in Portugal, in 1480. He studied map making and navigation while he was still a boy. By the time he was in his mid-twenties, he was sailing in large fleets and involved in combats. In the year 1519, with the support of the Emperor Charles V, Magellan set out to find a better route to the Spice Islands. He assembled a fleet of five ships which in spite of numerous problems and Magellan's death, circumnavigated the world in a single voyage.
