One of the oldest surviving explorers and adventurers of the 20th century, Bradford Washburn, has published his autobiography. Now in his 90s, Washburn looks back on his multifaceted career, which includes pioneering work in aerial photography in Alaska’s mountains, 13 first ascents of Alaskan peaks and a decades-long relationship with the National Geographic Society. The autobiography also offers rare photographs and little-known anecdotes about Washburn’s World War II service and other explorations.

“An Extraordinary Life: The Autobiography of a Mountaineering Icon,” by Bradford Washburn and Lew Freedman, is available in a 6- by 9-inch, hardbound, 320-page edition with 100 black-and-white photographs for $27.95.
