[Professor Jacques Fouad Acar, Africa and the "potluck"].

The biography of Professor Jacques Fouad Acar (1931-2020) shows the exceptional trajectory of an atypical doctor, infectiologist-clinician and microbiologist, propelled by the international dynamics of integration and social progress originating in the Lebanese diaspora with his first founding experiences in Dakar, Senegal, in French West Africa, during the golden age of French colonial medicine. Jacques Acar's imprint will comprise three remarkable dimensions: on the one hand, the promotion of integrated multidisciplinary clinical-biological reasoning in infectious pathology; on the other hand, independence of thought in the field of action, which will become his leitmotiv during his university hospital career, allowing him to integrate "pastoral esprit de corps" into his fundamental research at the Pasteur Institute in Paris on the molecular mechanisms of antibiotic resistance and to participate in the explosion of world medicine; lastly, his unique emotional intelligence potentiated by his instinctive sense of networking, with students of all origins and disciplines.
