Fawcett, Percy Harrison (1867-1925?), was an Englishman who explored the jungles of Brazil. He was an officer in the British Army and a trained surveyor. In 1906, the Royal Geographical Society, a British organization that sponsors scientific expeditions, invited Fawcett to survey part of the frontier between Brazil and Bolivia. He spent 18 months in the jungle, in the Mato Grosso area, where he learned much about the peoples of the jungle. After World War I (1914-1918), Fawcett returned to Brazil. Fascinated by stories of a hidden city, he planned an expedition into the interior. In 1925, with his son Zack and a friend of his son, he led an expedition into the jungle. Nothing was heard of the party again. His younger son Brian wrote of Fawcett's experiences in Exploration Fawcett (1953). Fawcett was born in Torquay, Devon, England.
