Amerigo Vespucci (/vɛˈspuːtʃi/; Italian: [ameˈriːɡo veˈsputtʃi]; 9 March 1451 – 22 February 1512) was an Italian merchant, explorer, and navigator from the Republic of Florence, from whose name the term "America" is derived. It is unknown whether Vespucci was ever aware of these honours. In 1505, he was made a citizen of Castile by royal decree and in 1508, he was appointed to the newly created position of piloto mayor (master navigator) for Spain's Casa de Contratación (House of Trade) in Seville, a post he held until his death in 1512.
