Fred Vargas is the pseudonym of the French historian, archaeologist and writer Frédérique Audoin-Rouzeau (born 7 June 1957 in Paris). Her crime fiction policiers have won three International Dagger Awards from the Crime Writers Association, for three successive novels: in 2006, 2008 and 2009. She is the first author to achieve such an honor. In each case her translator into English was Sîan Reynolds, who was also recognized by the international award.
Audoin-Rouzeau worked at the French National Centre for Scientific Research (CNRS), which she joined in 1988. She later joined the Institut Pasteur, as a eukaryotic archaeologist. She has undertaken a project on the epidemiology of the Black Death and bubonic plague, the result of which was a work considered definitive in the research area: Les chemins de la peste (Routes of the Plague) (2003).
Fred is the diminutive of her given name, Frédérique, while Vargas derives from the Ava Gardner character in the film The Barefoot Contessa. Her twin sister Joëlle, a painter, adopted the pseudonym of Jo Vargas.
