Edward Leicester Atkinson DSO AM RN (1881–1929) was a Royal Navy surgeon and Antarctic explorer who was a member of the scientific staff of Captain Scott's Terra Nova Expedition, 1910–13. He was in command of the expedition's base at Cape Evans for much of 1912, and led the party which found the tent containing the bodies of Scott, "Birdie" Bowers and Edward Wilson. Atkinson was subsequently associated with two controversies: that relating to Scott's orders concerning the use of dogs, and that relating to the possible incidence of scurvy in the polar party. He is commemorated by the Atkinson Cliffs on the northern coast of Victoria Land, Antarctica, at 71°18′S 168°55′E / 71.300°S 168.917°E.
Atkinson was born on 23 November 1881 in the Windward Isles, where he spent much of his childhood. He was educated at the Forest School, Snaresbrook, and received his medical training at St Thomas's Hospital, London, where he became the hospital's light heavyweight boxing champion. He qualified in 1906 and two years later joined the Royal Navy as a medical officer, based at the Royal Naval Hospital, Haslar, in Gosport, Hampshire. He was primarily a researcher, and had published a paper on gonorrhoeal rheumatism when he was appointed physician and parasitologist to the Terra Nova expedition.
