A Florentine merchant and navigator whose published accounts of the New World led mapmakers to name two continents after him.
Amerigo Vespucci was not the first European to reach the Americas, but he was the first to argue convincingly that these lands were a separate continent, a 'New World' unknown to the ancients. Working initially for the Medici family's commercial interests in Seville, he participated in several expeditions along the coast of South America around the turn of the 16th century. His real impact came from his lively, detailed letters describing the geography, flora, fauna, and indigenous peoples he encountered. These accounts, widely published across Europe, captured the public imagination. In 1507, a German cartographer, Martin Waldseemüller, proposed the new continent be called 'America' in Vespucci's honor on his world map, a name that stuck.

The world at every milestone
Vespucci was a friend and possible employer of Christopher Columbus's son, Ferdinand.
He likely never commanded his own expedition, serving as an observer or navigator on voyages led by others.
The famous 1507 Waldseemüller map that named America is known as 'the baptismal certificate of the New World'.
Some of his letters' authenticity and the veracity of certain voyages have been debated by historians for centuries.
