The hut was named after the Alpinist, Fritz Pflaum, who was born in 1871. He was a keen nature lover and sportsman and loved the Wilder Kaiser. On 25 August 1908 he died during a difficult mountain tour on the Mönch. Relatives, friends and acquaintances donated 8,000 marks for the construction of the Fritz Pflaum Hut, which was opened on 25 August 1912, exactly four years after his death. Subsequent attempts to rename it the Griesnerkar Hut have not succeeded. An attempt to provide a basic managed service in the spring of 2007 failed because of a ban by the district commission.
