“Lt. Colonel (United Kingdom) Percival Harrison Fawcett (18 August 1867 – in or after 1925) was a British artillery officer, archaeologist and South American explorer.
Along with his eldest son, Fawcett disappeared under unknown circumstances in 1925 during an expedition to find "Z" – his name for what he believed to be an ancient lost city in the uncharted jungles of Brazil.”

Dude was a real-life Indiana Jones.
