The legendary mountaineer Jim Whittaker, the first American to summit Mount Everest, has died at age 97. His family said in an emailed statement that he died Tuesday at home in Port Townsend, Washington. Whittaker’s 1963 ascent of Everest came 10 years after the pioneering climb of Sir Edmund Hillary and Tenzing Norgay. The feat made the once-shy, rangy climber an instant celebrity, in demand for public appearances and expected to lend his support to good causes. His family said Whittaker had an enduring belief in the power of nature to bring people together. Whittaker also served as the first full-time employee of the outdoor retailer REI and later as its president and CEO.
