Sir John RichardsonBorn 5 Nov 1787; died 5 Jun 1865 at age 77.Scottish naval surgeon and naturalist who made accurate surveys of more of the Canadian Arctic coast than any other explorer, in service with the Royal navy (1807-55). During this time he was surgeon and naturalist to Sir John Franklin's polar expeditions (1819-22, 1825-27). On the second expeditions, he separated from Franklin to explore the coast to the Coppermine River and Great Slave Lake (1826). He conducted a search expedition (1848-49) for Franklin's lost third Arctic expedition that had started in 1845, but was unable to find any trace of Franklin's ships. He wrote Fauna Boreali-Americana (1829-37) which became a standard work on Arctic biology. He also wrote on ichthyology and polar exploration. |
