Nawang Gombu Sherpa, who accompanied 2009 Mountainfilm special guest Jim Whittaker, during the first American ascent of Mt. Everest in 1963, died on Sunday April 24, 2011.

From Climbing magazine:

Gombu was born in Tibet and was the nephew of Tenzing Norgay, one of the first two men to climb Everest; he was the youngest climbing Sherpa on that 1953 expedition, reaching the South Col. In 1965, Gombu became the first man ever to climb Everest twice, summiting with an Indian expedition.
