I am reading a great article in Alpinist 62, by Peter Takeda, about the history of exploration and climbing on Nanda Devi. In his account of the climb Tilman made this observation which was spot on, but which was also sprinkled with some of his dry sense of humor.
"We live in an age of mechanization and, in recent years, it has become apparent that even mountaineering is in danger of become mechanized. It is therefore pleasing to record that in climbing Nanda Devi no mechanical aids were used — apart that is, from the Apricot Brandy."
