W. E. (Walter Ernest) Hardenburg

Born in 1886, Walter Ernest Hardenburg was an American author, journalist, and traveler. He is most closely associated with The Putumayo, the Devil's Paradise, a book published in the early 1910s that drew on his experiences in the Peruvian Amazon and helped document atrocities committed against Indigenous people during the rubber boom.

Hardenburg's writing is valued not just as travel narrative but as testimony. His work appeared alongside growing international concern about the Putumayo scandal, and it remains an important historical source for readers interested in the Amazon, colonial violence, and early human-rights reporting.

He also wrote on other subjects, including public health, showing a wider range than his most famous book alone suggests. Hardenburg died in 1942.
