Belgrave Edward Sutton Ninnis

Belgrave Edward Sutton Ninnis (22 January 1887 – 14 December 1912) was a Lieutenant in the Royal Fusiliers and an Antarctic explorer who was a member of Sir Douglas Mawson's 1911 Australasian Antarctic Expedition.

Antarctica 1911-1912
Following the fame he achieved on Ernest Shackleton's 1907 Nimrod Expedition to Antarctica, Douglas Mawson travelled to England in early 1910 to raise interest and sponsorship for an Australian Expedition focussed on scientific outcomes. On that trip he purchased the whaler Aurora and in London he loaded it with the many items of specialist equipment he was able to obtain there including 49 sledging dogs. Ninnis joined the Expedition in London as a minder of the Greenland dogs, and sailed with the Aurora on its voyage from London to Sydney commanded by Captain John King Davis. On the trip Ninnis formed a firm friendship with Dr. Xavier Mertz, a Swiss mountaineer who joined the Expedition in London and who was also appointed to handle the dogs.

Ninnis was in the 36-man party who set sail from Hobart on 2 December 1911. A base was built at Macquarie Island and a small party of five men were deployed to man a radio relay station and to conduct research. Ninnis landed in Antarctica with the main party Commonwealth Bay on 8 January 1912, and established the Main Base. The summer was spent building a hut at Cape Denison for the 18 man Adelie Land base party to winter in.

Ninnis was part of the three-man sledging team, the Far Eastern Party, with Mawson and Mertz who headed east on 10 November 1912 to survey King George V Land. After three weeks of excellent progress the party was crossing the Ninnis Glacier, when Ninnis fell through a snow-covered crevasse. Mertz had skied over the crevasse lid, Mawson had been on his sled with his weight dispersed but Ninnis was jogging beside the second sled and his body weight is likely to have breached the lid. Six dogs, most of the party's rations, their tent and other essential supplies disappeared into a massive crevasse 480 km east of the main base. Mertz and Mawson spotted one dead and one injured dog on a ledge 46 m down but Ninnis was never seen again.
