The Pasteur Hospital as an element of Emile Roux's anti-diphtheria apparatus (1890-1914).

Before the decisive discovery by Gaston Ramon of a vaccine ("anatoxine diphtérique") in 1923, the fight against diphtheria in France had started in 1894 with the serotherapy approach of Martin and Roux. Emile Roux, director of the Institut Pasteur, developed a dynamic concept of research/production/application expressed in the organization of a specialized hospital, the Hôpital Pasteur, which was constructed near the research laboratories and also incorporated production centres outside Paris in Marnes-la-Coquette. Roux implemented a well-defined project against diphtheria that took account of all of the logistical implications. By associating this therapeutic project with an architectural project, Roux established a coherent anti-diphtheria apparatus.
