Robert Edwin Hall was a New Zealand mountaineer. He was the head guide of a 1996 Mount Everest expedition during which he, a fellow guide, and two clients died. A best-selling account of the expedition was given in Jon Krakauer's book Into Thin Air and the expedition was dramatised in the 2015 film Everest. At the time of his death, Hall had just completed his fifth ascent to the summit of Everest, more at that time than any other non-Sherpa mountaineer.
