Amerigo Vespucci was an Italian explorer, navigator and cartographer born in Florence, Italy in 1451. He made four voyages to the New World between 1497-1503, exploring the coasts of South America and realizing that the lands discovered were not Asia but a "New World." Although Vespucci did not discover America, the continents were named after him when a map published in 1507 referred to the lands as the Americas. Vespucci advanced navigation, cartography and astronomy through his accurate calculations and by sharing his findings with other scholars.
