Sir Ranulph Fiennes was, with Charles Burton, the first man to reach both poles by surface travel and, with Mike Stroud, the first to cross the Antarctic Continent unsupported. In the 1960s he was removed from the SAS Regiment for misuse of explosives but, joining the army of the Sultan of Oman, received that country's Bravery Medal on active service in 1971. He is the only person yet to have been awarded two clasps to the Polar medal for both Antarctic and the Arctic regions. Fiennes has led over 30 expeditions including the first polar circumnavigation of the Earth. In 1993 the Queen awarded Fiennes the Order of the British Empire (OBE) because, on the way to breaking records, he has raised over £16 million for charity. In 2009 he became the oldest Briton to reach the summit of Everest.
