Exploration
In the Pacific Ocean, Jorge de Menezes (c. 1498–?), discovered Papua New Guinea. García Jofre de Loaísa (1490–1526), discovered the Marshall Islands. Explorations of the Americas began with the initial discovery of America by Christopher Columbus (1451–1506), who led a Castilian (Spanish) expedition across the Atlantic, discovering America. After the discovery of America by Columbus, a number of important expeditions were sent out to explore the Western Hemisphere. This included Juan Ponce de León (1474–1521), who discovered and mapped the coast of Florida; Vasco Núñez de Balboa (c. 1475–1519), who was the first European to view the Pacific Ocean from American shores (after crossing the Isthmus of Panama) confirming that America was a separate continent from Asia; Aleixo Garcia (14?–1527), who explored the territories of present-day southern Brazil, Paraguay and Bolivia, crossing the Chaco and reaching the Andes (near Sucre).
Joseph Fischer (cartographer)
Joseph Fischer, S.J. (; 19 March 1858 – 26 October 1944) was a German clergyman and cartographer. Fischer had an eminently successful career as a cartographer, publishing old maps. In 1901, while he was investigating the Vikings' discovery of America, he accidentally discovered the long-lost map of Martin Waldseemüller, dated 1507. This map, which claims to update Ptolemy with the voyages of Amerigo Vespucci, is the first known to display the word "America". The map was purchased from its owner by the United States Library of Congress in 2001 for ten million dollars.
