There is a book called "Eiger- Wall of Death" which is very cool. Its out of print, I read it from a library, it talked all about the early summit attempts and all the casualties and the crazy rescue attempts. Before the advent of helos, some of the bodies hung on their ropes, dangling in midair, unable to be retrieved, for years.
I was in that area a few years ago, it is thoroughly awesome for world class mountain hiking if thats your thing. Took the cog train up the mountain, up into the mountain, stopped at the window outlooks that were blasted into the mountain years ago for tourists. You look out the windows and the mountain is literally straight up and down there. You realize the serious balls it takes to climb up there. And we were there in late July, it was 85* in the valley with blazing sun. Up there on the mountain it was blowing hard and cold as chit (that is a scientific measurement).
