David Thompson (explorer)
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 and South Branch House before arriving at Manchester House in 1787. On December 23, 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 
In 1790 with his apprenticeship nearing its end, Thompson made the unusual request of a set of surveying tools in place of the typical parting gift of fine clothes offered by the company to those completing their indenture. He received both. He then entered the employ of the Hudson's Bay Company as a fur trader and in 1792 completed his first significant survey, mapping a route to Lake Athabasca (presently straddling the Alberta/Saskatchewan border). In recognition of his map-making skills, the company promoted him to surveyor in 1794. Thompson continued working for the Hudson's Bay Company until May 23, 1797 when, frustrated with the Hudson's Bay Company's policies, he left and walked 80 miles in the snow to enter the employ of the competition, the North West Company where he continued to work as a fur trader and surveyor.
