sir francis leopold mcclintock
British naval officer and explorer who discovered the tragic fate of the British explorer Sir John Franklin and his 1845 expedition to the North American Arctic. Before his own successful search of 1857-59, McClintock took part in three earlier efforts to find Franklin. On the second and third of these (1850-51 and 1852-54), his improvements in the planning and execution of sledge journeys greatly advanced the possibilities of Arctic exploration.
