A receptive mind, trained in investigative inquiry and steeped in experience with the medical problems of children, was responsible for the first recognition of cat-scratch disease. Serendipity was no part of the process. Robert Debré (Fig 1), Professor of Pediatrics at the University of Paris, writes:
The story of the discovery of cat-scratch disease is quite a curious one. In 1931, my co-worker, Dr. G.
