David Thompson

Died aged c. 87

David Thompson (30 April 1770 – 10 February 1857) was a British-Canadian fur trader, surveyor, and map-maker, known to some native peoples as "Koo-Koo-Sint" or "the Stargazer." Over Thompson's career, he travelled some 90,000 kilometres (56,000 mi) across North America, mapping 4.9 million square kilometres (1.9 million square miles) of North America along the way. For this historic feat, Thompson has been described as the "greatest land geographer who ever lived."
