Walter Ernest How (25 December 1885 – 5 August 1972) was an English sailor, known for taking part in the Ernest Shackleton-led Imperial Trans-Antarctic Expedition from 1914 to 1917. Born in Bermondsey, London, he became a sailor when he was 12 years old. He married Helen Varey in 1913, and his first daughter was born only six weeks before his departure on the Endurance. On return to England after their eventual rescue, How was awarded the Polar Medal and joined the Merchant Navy during the Great War.
