Blodig was the first to successfully climb all the Alpine peaks of over 4000 meters, completing his final summit in around 1900. He describes these climbs in his book "Die Viertausender der Alpen (The 4000-meter Alpine Peaks)", first published in 1923. There is a story about Dr. Karl Blodig in The Wildest Dream, Gillman, Peter and Leni Headline, 2000, pages 83–84. Dr.Blodig said after observing George Mallory, "That young man will not be alive for long." According to Gillmans, George was dismayed not only because he had been criticized by a guest but because Blodig's insinuation unjust.While he accepted that rock climbing entailed risk, he felt confident in his judgement and his technical ability. Gillmans continue the story on page 84. George had the last word. Dr. Blodig was in the Party led by George up Great Gully on Craig Yr Ysfa.When George reached an unpleasantly icy pitch Blodig announced he wanted to go back, but he was outnumbered by other climbers, including Cottie (Sanders). George climbed the icy section by combined tactics, which meant climbing on one of his partner's shoulders. "Unanimous cries of "Hurrah" and "Bravo" hailed this extraordinary performance," Cottie recorded, and the group = including a rueful Blodig - reached the top safely.
