David Thompson (born 1770-04-30; died 1857-02-10), a British-Canadian furtrader and surveyor, mapped 3.9 million square kilometers of North America. Navigating the full length of the Columbia River in 1811, he produced a high-quality map of the river basin. He has been called the greatest land geographer who ever lived.

Thompson's exploits are the basis for the novel "The Mapmaker," written by Frank Gill Slaughter and published in 1957.
