What happened
The Italian navigator Amerigo Vespucci sailed on Spanish and Portuguese expeditions along the South American coast in the years after Columbus's voyages, and argued in his own accounts that the land was not part of Asia, as Columbus believed, but a previously unknown continent, which Vespucci called Mundus Novus, the New World. In 1507, German cartographer Martin Waldseemuller published a geography book with a world map that labeled the southern landmass "America" in Vespucci's honor. Vespucci himself kept using the term Mundus Novus, but Waldseemuller's name stuck.
Why it matters
Waldseemuller's map is the first known document to use the name America for any part of the Western Hemisphere, and the label spread through European geographic circles until it applied to both continents. Vespucci's real contribution was recognizing a fact Columbus never accepted: that the Americas were not Asia.
How we know
The Mariners' Museum's Ages of Exploration entry on Vespucci names the 1507 Waldseemuller map and describes how the label America entered common use despite Vespucci's own preferred term.
