Prince Henry the Navigator (1394-1460) prepared the way for the great maritime expeditions of the 15th and early 16th centuries. At the Vila de Infante near Sagres in Portugal he ran an observatory and school of navigation. He financed voyages along the coast of Africa, as well as to the Canary Islands, Azores, and Madeira Islands in the Atlantic Ocean. Henry is best known for encouraging voyages of exploration and the scientific study of navigation. He himself didn't go on any of the voyages he sponsored.
