The Pioneers

Vittorio Sella was born in Biella, Italy in 1859. Sella’s love of the mountains was fostered by his uncle, Quintino Sella, and his study of landscape painting informed the style of his photography. The awe-inspiring images of the Jannu and Kangchenjunga Glaciers, as well as the Karakoram’s Lower Baltoro Glacier, were taken with a Ross & Co. Camera, using 24 x 18 cm plates.

Norman Günter Dyhrenfurth (May 7, 1918) was born in Breslau, Germany to accomplished mountaineers Günter and Hettie Dyhrenfurth. Following his service as a soldier in WWII, he became first a director of a motion picture company and then head of the prestigious UCLA film school. In 1952, Dyhrenfurth joined the second Swiss expedition to Mount Everest. From above their camp on the Khumbu Glacier, he took breathtaking panoramic views using a Speed Graphic Camera with 10 x 13 cm plates. (Image courtesy of Archive Norman G.

George Herbert Leigh Mallory was born in 1886 in Mobberley, Cheshire. As a member of the 1921 British Reconnaissance Expedition, Mallory and his party explored routes on Mount Everest and produced the first accurate maps of the region, using a Sinclair UNA quarter plate camera. In 1922 Mallory returned to Everest, and attained a record altitude of 8225 m before he and his team were forced to turn back. His final Everest expedition took place in 1924. Mallory and his climbing partner, Andrew Irvine, set off from Advanced Base Camp on 4 June. Four days later, they left Camp 6 and disappeared on the mountain. They were never heard from again.

Major Major Edward Oliver Wheeler was born in Ottawa, Ontario in 1890 to Arthur and Clara Wheeler. Wheeler’s early mountaineering experience was on Canadian peaks, but in 1921 he joined the British Reconnaissance Expedition to Mount Everest as a surveyor. The members of this team were the first Westerners to approach the north side of Mount Everest through Tibet. It was during this expedition, using a Canadian photo-topographical survey camera with 12 x 17cm plates, that Wheeler took the extraordinary single images and panoramas of the Kyetrak, East Rongbuk and West Rongbuk Glaciers. In 1927 Wheeler returned to India and was the Surveyor-General from 1941-47. In 1943 he was knighted in recognition of his work. (Image courtesy of the Royal Geographical Society)
