This article analyzes the transfer of housing occupancy which took place in Paris from 1942 onwards under the supervision of an administrative service of the Préfecture de la Seine that was in charge of reallocating the “Jewish homes” left empty to the victims of the war. The aim is to address the issue of anti-Semitism based on the study of an actual piece of public policy, in this case housing, and to raise questions related to the social appropriation of anti-Semitism as well as its internal dynamics. It considers the social networks and the sociology of the actors at work: Who they are and how they perceive and name what they do. In order to assess the motives of the “chasers of empty houses,” the article seeks to probe the interrelations between, and the respective weights of the economic deprivation—housing specifically—on the one hand, and anti-Semitic stances promoted by the French State racial persecution policy on the other hand. At the junction of representation and practical situation, anti-Semitism is grasped here in its social density and complexity, with the area of Paris as its field of inquiry.
