Dr. Lewis Griffith Cresswell Evans Pugh
Pugh’s research for the Medical Research Council in 1951–52 was largely responsible for the solution to the “problem of the last thousand feet” on Everest, and he then joined the 1953 party. He led a physiological expedition to the Everest region in 1960–61, the first to winter at a height of 19,000 feet (5790 m).
Himself an Olympic-class skier, Pugh was a physiologist who specialized in the reaction of the body to extreme conditions. He had worked in the Middle East during World War II, and in Antarctica on physiological problems. His work on hypothermia in more normal conditions undoubtedly saved the lives of many people. He also studied the performance of long-distance swimmers, as well as Olympic athletes, with particular reference to the 1968 Games at Mexico City (held at an altitude of 7300 feet/2225 m).
