author
Very little biographical information about this author appears to be readily available online, which gives the work an added sense of mystery. Jean Quéré seems to be one of those lesser-documented writers whose books have outlasted the details of a public life.

by Jean Quéré
Jean Quéré is not well documented in the major easily accessible reference sources I could confirm during this search. I was not able to verify standard biographical details such as dates, places, or a fuller literary profile with enough confidence to present them as fact.
That said, the name does appear in library and web searches connected with French-language material, suggesting an author whose work has circulated more quietly than that of widely profiled literary figures. For readers, that can be part of the appeal: discovering a writer through the text itself rather than through an already familiar public story.
Because I could not confirm a reliable portrait from a trustworthy source, no author image is included here.
