David Thompson (30 April 1770 – 10 February 1857) was a British-Canadian fur trader, surveyor, and cartographer, known to some native people as "Koo-Koo-Sint" or "the Stargazer".
Over Thompson's career, he travelled 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 practical land geographer that the world has produced".
