Amerigo Vespucci
Amerigo Vespucci (9 March 1451- 22 February 1512) was an Italian merchant, explorer and cartographer. He was the first person to explain that the places discovered by Christopher Columbus in 1492 were not part of east Asia, but an unknown continent which he called "The New World". America got its name when other cartographers used a feminized and latinized version of his first name, Americus.
