Babu Chiri Sherpa
...has this Bio
An Everest legend, Babu is the first and only climber to spend a night (21 hours) on top of Mt Everest. He did this without supplmental oxygen. His untimely death may be what has prevented him from being even more widely known. He held the record for the fastest climb of Mt Everest, at 16hr and 56m, for some years. All that knew him found him an impressive presence whether they understood the full import of his accomplishments or not.
