Dumézil and Lévi-Strauss, he would become a member of the "Paris School", originally composed of Jean-Pierre Vernant, Nicole Loraux, Marcel Detienne and himself. Their work would renew approaches to the study of Ancient Greece. He then worked at the CNRS (1962–64) and was named maître de conférences at the University of Lyon (1964–66). He was then named professor at the École pratique des hautes études, which became the EHESS. Vidal-Naquet co-authored several books with his colleague and friend Jean-Pierre Vernant. However, although Vernant was a "comrade" of the French Communist Party (PCF), Vidal-Naquet never belonged to any political party, with the exception of the Unified Socialist Party (PSU), which he considered a "mere discussion circle." Pierre Vidal-Naquet was married and the father of three children. He was also officer of the Légion d'honneur and, in Greece, commander of the Phenix Order. Pierre Vidal-Naquet was an atheist. Activism Pierre Vidal-Naquet defined himself as an "activist historian", and while pursuing his studies never ceased engaging in political struggles and taking part in political committees, etc. A member of the Comité Audin, along with Jérôme Lindon (editor of the Minuit publishing house), he was one of the best known opponents of the use of torture by the French Army during the Algerian War (1954–62). Along with Jean-Paul Sartre and 119 others, he signed the Manifesto of the 121, a call for civil disobedience against the Algerian war. As an anti-colonialist, Vidal-Naquet was opposed to Guy Mollet's French Section of the Workers' International (SFIO) reformist party because of Mollet's support of the First Indochina War and Algerian War. He was also opposed to the Regime of the Colonels (1967–74) in Greece. He supported peace efforts in the Middle East as well as the Europalestine group. He thus declared: "I consider Sharon a criminal." With Michel Foucault and Jean-Marie Domenach, on 8 February 1971 he signed the manifesto of the Groupe d'informations sur les prisons, which, rather than speaking in the name of prisoners, aimed to give back to them the chance of speaking in their own voice. Vidal-Naquet was also active in condemning denial of the Armenian genocide. Vidal-Naquet, who had answered or criticized Holocaust negationist Robert Faurisson in several of his works, once employed Faurisson as an example to illustrate "what the Armenian minorities might feel": Let us imagine a negationist Robert Faurisson as a governmental minister, a Faurisson president of the Republic,
