Owen Chase was born in 1797 and worked as a whaler in Nantucket. In November 1820, the whale ship Essex, of which Chase was First Mate, was struck and sunk by a sperm whale. His subsequent account of the three-month-long ordeal that followed was published in 1821 and inspired Herman Melville to write Moby-Dick. Afterwards, Chase continued to work as a whaler, embarking on several further expeditions until 1840. Despite many years at sea he married four times during this period. Chase s latter years were haunted by memories of the disaster and he was eventually institutionalised. He died in 1869.
