Rear-Admiral Sir John Franklin KCH FRGS RN (16 April 1786 – 11 June 1847) was a British Royal Navy officer and Arctic explorer. Franklin also served as governor of Tasmania for several years. In his last expedition, he disappeared while attempting to chart and navigate a section of the Northwest Passage in the Canadian Arctic. The entire crew perished from starvation, hypothermia, tuberculosis, lead poisoning and scurvy, and the expedition's icebound ships were abandoned in desperation. Franklin was born in Spilsby, Lincolnshire, in 1786 and educated at King Edward VI Grammar School, Louth. John Franklin was the ninth of twelve children. One of his sisters was the mother of Emily Tennyson. Franklin's father initially opposed his son's interest in a career at sea. However, Franklin was determined and his father reluctantly allowed him to go on a trial voyage with a merchant ship. This hardened young Franklin's resolve, so at the age of 14 his father secured him a Royal Navy appointment on HMS Polyphemus. Franklin was later present at a number of historic voyages and naval battles.
