Born in or near the year 1457, the Spanish explorer Vasco Nunez de Balboa was the first European to see the eastern shore of the Pacific Ocean. He sighted the ocean in 1513 from a mountaintop in what is now Panama. Upon reaching the shore, Balboa waded into the ocean and claimed it and all its shores for Spain.
