In reply to iceox:
There are a myriad of sources ... a good read on Ben Nevis (one of the Norrie Muir stomping grounds) is Ken Crocketts book.
Maybe because I was climbing just a bit later than they were doing things it was their names in Mountain Magazine and other books - this was pre-internet remember - an that was in NZ so I am sure you can find a few sources Alpine Journal, SMC etc
