Who is Jon Krakauer from The Climb: Tragic Ambitions on Everest and what is their importance?

Krakauer was a writer for Outside Magazine who originally intended to sign on with Scott Fischer's climbing company but switched to join Rob Hall's group. Upon returning from the expedition, Krakauer wrote an article and then a book about his experience. In his account, Krakauer portrayed Boukreev in a mostly negative light. "The Climb" addresses and attempts to counter Krakauer's version of events.
