Answer: Hiram Bingham III — an American historian and explorer from Yale University
Machu Picchu, the 15th-century Inca citadel built c.1450 AD by Emperor Pachacuti, was abandoned after the Spanish conquest of the Inca Empire in the 16th century. Its existence was unknown to the wider world until 1911, when American historian Hiram Bingham III was led there by local Peruvian farmers. Bingham was a Yale University professor. Machu Picchu sits at 2,430 metres above sea level in the Andes and became a UNESCO World Heritage Site in 1983.
