Acclaimed hillwalking writers Ian R Mitchell and George Rodway tell the fascinating story of Aberdeen-born Alexander Kellas, and his contribution to mountaineering from the 20th century to the present day. Now a largely neglected figure, Kellas is the pioneer of high altitude physiology, his climbing routes still in evidence today. Follow Kellas' journey, which takes him from the Scottish Cairngorms to the Himalaya, and discover how his struggles and explorations have impacted upon mountaineering today.

A century ago the summits of the world's highest peaks, Everest included, were beyond reach. Pioneering attempts to overcome the dangers of climbing at extremely high altitudes ended in failure, sometimes with disastrous consequences. Yet today high-altitude ascents are frequent, almost commonplace. Everest can be conquered by relatively inexperienced mountaineers, and their exploits barely merit media attention - unless they go fatally wrong. In this fascinating study of the dramatic history of Everest climbs, Richard Sale and George Rodway describe in vivid detail the struggle to conquer the mountain and the advances in scientific knowledge that made the conquest possible. Their account gives a compelling insight into the science of mountaineering as well as the physical and psychological challenges faced by individuals who choose to test themselves in some of the harshest conditions on earth. Dr George Rodway, an assistant professor at the University of Utah, is a physiologist, mountaineer and an expert on mountain medicine and the science of high-altitude climbs. As well as publishing many papers and articles on these subjects, he is the editor of George Ingle Finch's The Struggle for Everest. He has also written extensively on the history of high-altitude physiology for journals such as High Altitude Medicine and Biology.
