Sir Francis Leopold McClintock (1819-1907) was an Irish adventurer and explorer known for his discoveries in the Canadian Arctic Archipelago. He joined the navy in 1831 and over the course of his career participated in countless expeditions. The most famous of these expeditions is probably the voyage of the Fox in 1857, which finally discovered proof of the fate of Sir John Franklin and his crew, who had disappeared in 1845. McClintock is also credited with perfecting certain sledging techniques and completing the mapping of the final sector of unexplored mainland Arctic coastline in the Boothia Peninsula area. Knighted in 1860, and promoted to admiral in 1884, he was known for his generosity and his exceptional skill as an Arctic explorer.
