An Italian explorer, Christopher Columbus, wanted to discover a direct water route from Europe to Asia. In his four voyages across the Atlantic Ocean from Spain, however, what he ended up discovering was not Asia, but America. Though he was not the first one to land in America, his historical journey began what eventually turned into Spanish colonization of America.
Marco Polo was a Venetian explorer, writer, and merchant. He explored Asia along the Silk Road and is credited with providing the Europeans with descriptions of the culture of the Eastern world, which remained unknown until his exploration. Polo's travel book inspired other travelers like Christopher Columbus. His writings also influenced European cartography, which led to the Fra Mauro map.
Amerigo Vespucci was a merchant, navigator, and explorer. Credited with participating in two major voyages of the Age of Discovery, Vespucci's claim that the New World represented a new continent inspired cartographers to associate the name America (a Latinized form of his first name) to the newly discovered continents.
Walter Bonatti was an Italian explorer, mountain climber, and journalist. He made a solo climb of a new route on the southwest pillar of the Aiguille du Dru in August 1955, among other achievements. He retired from mountaineering at the age of 35 and pursued a career as a reporter. He also wrote several books on mountaineering.
