I am reading Savage Summit by Jennifer Jordan (William Morrow, 2005), the Savage Summit being K2. Jordan also recounts the attempts on Everest by Allison Hargreaves, which culminated in her successful ascent in May 1995, without supplemental oxygen or outside (e.g., Sherpa) assistance or using ropes set by other groups.
Jordan emphatically states that Hargreaves was the first person after Reinhold Messner, to accomplish this feat. I am by no means an expert in the history of climbing, but I have read fairly widely, and I was surprised to read this. I had thought that the Polish climber, Jerry Kukuczka was the first to repeat Meissner's ascent of Everest without supplemental oxygen. However, according to my Google search, Kukuczka was the first after Meissner to climb all fourteen 8-thousanders, thirteen of which he climbed without supplemental oxygen; he used supplemental oxygen on Everest.
My Google search for the second person either ignored Hargreaves entirely or named her as the first woman to summit Everest without supplemental oxygen. I would have expected Hargreaves to pop up this search.
Was Hargreaves in fact the first person after Messner to climb Everest without supplemental oxygen and without outside assistance? I am not a careless reader, and if Hargreaves had received a significant fraction of the notice in the literature as did Kukuczka (who was a superman), I would have noticed it.
