Hiram Bingham
From Tardis Wiki, the free Doctor Who reference
Hiram Bingham was an explorer who searched for the lost city of Macchu Picchu in Peru in 1911. (COMIC: Hitching Point)
This is historical fact. Also known as Hiram Bingham III, Hiram did indeed make public the existence of Macchu Picchu on the claimed date. He also later joined the military and became a member of the U.S. Senate.
