General information: Born in Florence, on the Italy peninsula. He was the third son of Ser Nastagio (Anastasio), a Florentine notary, and Lisabetta Mini. He was educated by his uncle, Fra Giorgio Antonio Vespucci, a Dominican friar of the monastery of San Marco in Florence.
America: 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 the feminine Latin version of Vespucci's first name, which is Americus. In an accompanying book, Waldseemüller published one of the Vespucci accounts, which led to criticism that Vespucci was trying to upset Christopher Columbus glory.

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. The names of Amerigo Vespucci's ships were the San Antiago, Repertaga, Wegiz, and the Girmand.
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.
FOURTH VOYAGE: Vespucci's fourth voyage was another expedition for the Portuguese crown down the eastern coast of Brazil, that set out in May 1503 and returned to Portugal in June 1504. Like his alleged first voyage, Vespucci's last voyage in 1503–1504 is also disputed to have taken place. The only source of information for the last voyage is the Letter to Soderini, but as several modern scholars dispute Vespucci's authorship of the letter to Soderini, it is also sometimes doubted whether Vespucci undertook this trip.[b] However, Portuguese documents do confirm a voyage to Brazil was undertaken in 1503–04 by the captain Gonçalo Coelho, very likely the same captain of the 1501 mapping expedition (Vespucci's third voyage), and so it is quite possible that Vespucci went on board this one as well. However, it is not independently confirmed Vespucci was aboard and there are some difficulties in the reported dates and details.
FINAL YEARS: Not long after his return to Spain, Vespucci became a Spanish citizen. On March 22, 1508 he was made the pilot major of Spain by Ferdinand II of Aragon in honor of his discoveries. Vespucci also ran a school for navigators in the Spanish House of Trade, based in Seville.
