Bradford Washburn

Henry Bradford Washburn, Jr. (June 7, 1910 - January 10, 2007) was an explorer, mountaineer, photographer, and cartographer. He established the Boston Museum of Science, served as its director from 1939–1980, and from 1985 until his death served as its Honorary Director (a lifetime appointment).
Washburn is especially noted for exploits in four areas.
He was one of the leading American mountaineers in the 1920s through the 1950s, putting up first ascents and new routes on many major Alaskan peaks (often with his wife, Barbara Washburn, one of the pioneers among female mountaineers).
He pioneered the use of aerial photography in the analysis of mountains and in planning mountaineering expeditions. His thousands of striking black-and-white photos, mostly of Alaskan peaks and glaciers, are known for their wealth of informative detail and their artistry. They are the reference standard for route photos of Alaskan climbs.
He was responsible for creating maps of various mountain ranges; his map of Mount McKinley and his map of Mount Everest are perhaps the most notable, although his map of the Presidential Range in New Hampshire was closer to home.
His stewardship of the Boston Museum of Science made it into a first-class museum.
Also notable is the fact that some of these achievements – e.g. the Everest map and subsequent further work on the elevation and geology of Everest – were carried out in his 70s and 80s. (read more wikipedia)
