In 1454, on this day in world history, cartographer and explorer Amerigo Vespucci was born. Born in Florence, his work as a cartographer would prove Columbus wrong, as he demonstrated the fact that these lands discovered by him in 1492 were in fact, a new continent. He traveled about four times to South America with the Spanish and Portuguese ships, and eventually moved to Seville, Spain. He died in 1512, at the age of fifty-seven. His work as a cartographer of the Americas led later workers of the same profession to name the continent after him, as America.
