I believe Joe Brown, Doug Scott AND Chris Bonnington are all alive although getting on in years.
Haston died in an avalanche.
Don Whillans died of a heart attack in his bed.
The Internation School of Mountaineering in Leysin was started by the American John Harlin who died on the winter ascent of the Eiger direct when a rope broke while he was jumaring. Haston completed the climb with a German team and then became the head of the Climbing School in Leysin.
Haston was not a good businessman but the "Club Vagabond" in Leysin became a place of debauchery at it's finest headed up by Haston and his disciples.
Harlin's son, John Harlin III is an accomplished climber and BC skier and was the editor of the annual American Alpine Journal.
Two great books about these two are:
Dougal Haston, The Philosophy of Risk by Jeff Connor
and
The Villain, a portrait of Don Whillans by Jim Perrin.
Great books about two of the most iconic figures of alpine climbing and mountaineering and both Grade A psychopaths.
