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 called the lands the "Americas" for the first time. Vespucci advanced navigation, cartography and astronomy through his accurate measurements and by sharing his findings with other scholars.
