Docteur Jaf

Docteur Jaf was a pen name used by Jean Fauconney, a French author whose name appears in library and ebook records alongside that pseudonym. His surviving books suggest a writer interested in subjects that were often treated as scandalous or educational at the same time: sexuality, desire, bodily behavior, and the history of vice.

Works attributed to him include titles such as L'amour secret and Physiologie du vice, and Project Gutenberg also lists Jean Fauconney as an alias for Docteur Jaf. That points to an author who wrote for a broad readership rather than a strictly academic one, using the authority of the "doctor" persona to explore intimate and controversial themes.

Biographical details about his life are limited in the sources I could confirm, so a full personal portrait remains uncertain. What is clear is that the name Docteur Jaf became attached to a distinctive corner of French popular writing in the early 1900s, where medicine, morality, and curiosity often met.
