Anatoli Boukreev was one of the world's foremost high-altitude mountaineers, arguably the finest of his generation. He had summited eleven of the world's 8,000 meter peaks without the use of supplementary oxygen, some of them, including Mount Everest, multiple times. In all, he attempted twenty-one times he was successful. Born in Russia where he received the Master of Sports with Honors, Boukreev had made his home in Kazakhstan where in 1998 the President of that Republic awarded him posthumously the "Erligi Ushin" Medal for his contributions to high-altitude mountaineering and for his personal courage.
