Hiram Bingham III was an archaeologist and lecturer of history at Yale. His wife had money, and he was able to finance his own exploration in South America.  In 1911 he led an expedition to Peru in search of the lost city of the Incas.  By July, a farmer led him to “Old  Mountaintop,” or “Machu Picchu.” The find made him famous. Historian John Schmidt tells us the story of how Bingham found Machu Picchu.
