 The ambiguous wording of Detzner 's resignation from the Geographical Society of Berlin — the use of such phrases as contains misrepresentations , scientific report in part only , primarily fictional , unusual circumstances in Germany , and so on — misled later scholars , many of whom remained unaware of the controversy surrounding his book . Consequently , his work continued to inform the geographical , linguistic , and anthropological investigations of New Guinean culture and geography well into the 1950s and 1960s , much to the dismay of Ernst Mayr , who had been instrumental in discrediting Detzner in the 1920s .
