Amerigo Vespucci (Italian pronunciation: [ameˈriɡo vesˈputtʃi]) (March 9, 1454 – February 22, 1512) was an Italian explorer, financier, navigator and cartographer who first demonstrated that Brazil and the West Indies did not represent Asia's eastern outskirts as initially conjectured from Columbus' voyages, but instead constituted an entirely separate landmass hitherto unknown to Afro-Eurasians. Colloquially referred to as the New World, this second super continent came to be termed "America", probably deriving its name from the feminized Latin version of Vespucci's first name.
Background
Amerigo Vespucci was born and raised in Florence, Italy. He was the third son of Ser Nastagio (Anastasio), a Florentine notary, and Lisabetta Mini.Amerigo Vespucci was educated by his uncle, Fra Giorgio Antonio Vespucci, a Dominican friar of San Marco in Florence. While his elder brothers were sent to the University of Pisa to pursue scholarly careers, Amerigo Vespucci embraced a mercantile life, and was hired as a clerk by the Florentine commercial house of Medici, headed by Lorenzo de Medici. Vespucci acquired the favor and protection of Lorenzo Pierfrancesco de Medici who became the head of the business after the elder Lorenzo's death in 1492. In March 1492, the Medici dispatched the thirty-eight year old Vespucci and Donato Niccolini as confidential agents to look into the Medici branch office in Cadiz (Spain), whose managers and dealings were under suspicion.n April, 1495, by the intrigues of Bishop Juan Rodríguez de Fonseca, the Crown of Castile broke their monopoly deal with Christopher Columbus and began handing out licenses to other navigators for the West Indies. Just around this time (1495–96), Vespucci was engaged as the executor of Giannotto Berardi, an Italian merchant who had recently died in Seville. Vespucci organized the fulfillment of Berardi's outstanding contract with the Castilian crown to provide twelve vessels for the Indies.After these were delivered, Vespucci continued as a provision contractor for Indies expeditions, and is known to have secured beef supplies for at least one (if not two) of Columbus's voyages.Expeditions
At the invitation of king Manuel I of Portugal, Vespucci participated as observer in several voyages that explored the east coast of South America between 1499 and 1502. On the first of these voyages he was aboard the ship that discovered that South America extended much further south than previously thought.The expeditions became widely known in Europe after two accounts attributed to Vespucci were published between 1502 and 1504. In 1507, Martin Waldseemüller produced a world map on which he named the new continent America after Vespucci's first name, Amerigo. In an accompanying book, Waldseemüller published one of the Vespucci accounts, which led to criticism that Vespucci was trying to upset Christopher Columbus' glory. However, the rediscovery in the 18th century of other letters by Vespucci, primarily the Soderini Letter, has led to the view that the early published accounts could be fabrications, not by Vespucci, but by others.
He died on February 22, 1512 in Seville, Spain, of an unknown cause.
Historical role
In 1508, after only two voyages to the Americas, the position of chief of navigation of Spain (piloto mayor de Indias) was created for Vespucci, with the responsibility of planning navigation for voyages to the Indies.

First voyage
A letter published in 1504 purports to be an account by Vespucci, written to Soderini, of a lengthy visit to the New World, leaving Spain in May 1497 and returning in October 1498. However, modern scholars have doubted that this voyage took place, and consider this letter a forgery. Whoever did write the letter makes several observations of native customs, including use of hammocks and sweat lodges.Second voyage
About 1499–1500, Vespucci joined an expedition in the service of Spain, with Alonso de Ojeda (or Hojeda) as the fleet commander. The intention was to sail around the southern end of the African mainland into the Indian Ocean.After hitting land at the coast of what is now Guyana, the two seem to have separated. Vespucci sailed southward, discovering the mouth of the Amazon River and reaching 6°S, before turning around and seeing Trinidad and the Orinoco River and returning to Spain by way of Hispaniola. The letter, to Lorenzo di Pierfrancesco de' Medici, claims that Vespucci determined his longitude celestially on August 23, 1499, while on this voyage. However, that claim may be fraudulent,which could cast doubt on the letter's credibility.
Third voyage
The last certain voyage of Vespucci was led by Gonçalo Coelho in 1501–1502 in the service of Portugal. Departing from Lisbon, the fleet sailed first to Cape Verde where they met two of Pedro Álvares Cabral's ships returning from India. In a letter from Cape Verde, Vespucci says that he hopes to visit the same lands that Álvares Cabral had explored, suggesting that the intention is to sail west to Asia, as on the 1499-1500 voyage. On reaching the coast of Brazil, they sailed south along the coast of South America to Rio de Janeiro's bay. If his own account is to be believed, he reached the latitude of Patagonia before turning back, although this also seems doubtful, since his account does not mention the broad estuary of the Río de la Plata, which he must have seen if he had gotten that far south. Portuguese maps of South America, created after the voyage of Coelho and Vespucci, do not show any land south of present-day Cananéia at 25° S, so this may represent the southernmost extent of their voyages.After the first half of the expedition, Vespucci mapped Alpha and Beta Centauri, as well as the constellation Crux, the Southern Cross. Although these stars had been known to the ancient Greeks, gradual precession had lowered them below the European horizon so that they had been forgotten. On his return to Lisbon, Vespucci wrote in a letter to d'Medici that the land masses they explored were much larger than anticipated and different from the Asia described by Ptolemy or Marco Polo and therefore, must be a New World, that is, a previously unknown fourth continent, after Europe, Asia, and Africa.
