Who stumbled upon the peninsula of Florida in search for the fountain of youth?

Spanish explorer Juan Ponce de León is credited with stumbling upon the peninsula of Florida in 1513 while searching for the legendary Fountain of Youth. He named the area "La Florida" due to its lush, floral landscape and the timing of his arrival during the Easter season, known as Pascua Florida. Ponce de León's expedition marked the first known European contact with the region.
