Rear-Admiral Sir John Franklin (16 April 1786 – 11 June 1847) was a British Royal Navy officer and explorer of the Arctic. Franklin also served as Lieutenant-Governor of Van Diemen's Land (now Tasmania) from 1837 to 1843. He disappeared on his last expedition, attempting to chart and navigate a section of the Northwest Passage in the Canadian Arctic. The icebound ships were abandoned and the entire crew perished from starvation, hypothermia, tuberculosis, lead poisoning and scurvy.
