Thompson David 1770-1857 Born In The Parish Of St John's


Westminster, England. Educated at the Gray Coat School; and entered the

service of the Hudson's Bay Company, 1784. The first of his voluminous

journals opens at Fort Churchill in that year. The last is dated 1850.

The journals fill forty-five volumes of manuscript, and cover a period

of sixty-six years. Remained in the service of the Hudson's Bay Company

until 1797, and in that period carried on explorations and surveys of
/> the Nelson, Churchill, and Saskatchewan Rivers, and the intervening

territory. In 1797 joined the North West Company, and in the years that

followed, explored the upper waters of the Assiniboine; made a journey

overland to the Mandan villages on the Missouri; and another to the head

waters of the Mississippi; and surveyed portions of the upper waters of

the Saskatchewan, Athabaska, and Peace Rivers. From 1807 to 1811,

explored the entire system of the Columbia and Kootenay Rivers, from

source to mouth. Left the North-West in 1812, and from 1816 to 1826

engaged in surveying and defining the international boundary. Afterwards

carried out several minor surveys, in what is now eastern Canada. Died
