Leonard Duncan Albert Hussey OBE (6 June 1891 – 25 February 1964) was an English meteorologist, archeologist, explorer and member of Ernest Shackleton's Imperial Trans-Antarctic and Shackleton–Rowett Expeditions. During the latter, he was with Shackleton at his death, and transported the body part-way back to England. Hussey was also a member of the armed forces during World War I, serving in France and with Shackleton in Russia. After returning to private practice, Hussey rejoined the war effort in 1940 and became a decorated medical officer with the Royal Air Force during the Second World War. Returning once again to civilian practice in 1946, he was a member of the Royal College of Physicians, a lecturer, author, and Boy Scouts leader prior to retirement. Many of the items he collected during his career were donated to a number of museums.
