Query: Wall of Death

I found this book in the "english" section of a bookstore in Grindlewald and it was my introduction to the facinating world of mountaineering through literature. I have read many similir books since and nothing compares to this series of harrowing tales that progresses from the earliest climbs, through the first successful climb in the 30's and on to the stories of the worlds finest climbers and their attempts on this infamous wall. I was afraid to sleep after reading the Kurtz chapter it was so utterly depressing.
