Abstract
This paper is prompted by the publication of a book by Henry Louis Gates, Jr. and Andrew S. Curran on the contest launched in 1739 by the Bordeaux Academy on the origin of black skin and hair. The most influential work submitted as part of this contest was an essay by Pierre Barrère. This paper has two parts, one devoted to a review of the book, the other to the discovery of a cogent text, which was certainly written by a member of the Lyon Academy, Guillaume Rey. Rey criticized Barrère’s essay and debunked various beliefs about the origin of black skin that were commonly held at the time of its publication.
