Mountain climber extraordinaire who was the the only member to complete all four expeditions to Everest in the 1930s.
He climbed a mountain at age 15, and within a couple of years he started devoting himself to climbing.
He continued climbing even into his 50s, when he scaled a mountain in Patagonia, between Argentina and Chile.
His father died when he was three, and his mother raised the family on her own.
Sir Edmund Hillary is another famous climber who also mounted Everest.
