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."

Thompson was born in Westminster to recent Welsh migrants, David and Ann Thompson. When Thompson was two, his father died and the financial hardship of this occurrence resulted in his and his brother's placement in the Grey Coat Hospital, a school for the disadvantaged of Westminster. He eventually graduated to the Grey Coat mathematical school and was introduced to basic navigation skills which would form the basis of his future career. In 1784, at the age of 14, he entered a seven-year apprenticeship with the Hudson's Bay Company. He set sail on 28 May of that year, and left England .

He arrived in Churchill (now in Manitoba) and was put to work copying the personal papers of the governor of Fort Churchill, Samuel Hearne. The next year he was transferred to nearby York Factory, and over the next few years spent time as a clerk at Cumberland House, Saskatchewan, and South Branch House before arriving at Manchester House in 1787. On 23 December 1788, Thompson seriously fractured his leg, forcing him to spend the next two winters at Cumberland House convalescing. It was during this time he greatly refined and expanded his mathematical, astronomical, and surveying skills under the tutelage of Hudson's Bay Company surveyor Philip Turnor. It was also during this time that he lost sight in his right eye.
