Karl Blodig

Karl Blodig (16 October 1859 – 7 September 1956) was an Austrian mountaineer, optician, and writer. Blodig was the first to successfully climb all Alpine peaks of over 4000 meters, completing his final summit around 1911. He wrote about these climbs in his book Die Viertausender der Alpen (The Four-Thousanders of the Alps), first published in 1923.
