Juan Ponce de León was a Spanish explorer born in 1460 who led expeditions in the early 1500s hoping to find riches and the Fountain of Youth. On his first voyage in 1513, he encountered Florida while searching northwest of Hispaniola. He named Florida and became the first governor of Puerto Rico. Though he never found the Fountain of Youth, Ponce de León made important discoveries and helped expand Spain's claims in the Americas.
