Physicians have long believed that disturbing experiences arouse intense emotions that can cause illness and disease. Similarly, human behaviors that can be interpreted in the diagnostic language of our own time as post-traumatic pathology date back to classical times. The first medical instances of describing, labeling, and treating such behaviors appeared during the seventeenth century, when army doctors typically regarded the cases as an organic disease of an unknown nature, cowardice, or malingering. Traumatic neurosis as a distinct psychiatric category, however, with an independent diagnostic identity and psychological – or mixed somatic and psychological – origins emerged in Western Europe and North America only during the last third of the nineteenth century.

The period 1870–1910 witnessed an unprecedented burst of creative psychological theorizing in Europe and the United States. This was the founding generation of modern psychology, psychiatry, and psychotherapy during which the sciences of the mind largely assumed the theoretical and professional forms in which we know them today. The observation and theorization of psychological trauma played no small part in this intellectual development. One of the first physicians of this period to explore systematically the idea of posttraumatic pathology and to write extensively about it – and who was a direct and demonstrable inspiration to medical traumatologists in the next generation – was the Parisian neuropsychiatrist Jean-Martin Charcot.

THE BACKGROUND TO CHARCOT'S WORK ON TRAUMATIC NEUROSIS

Charcot (1825–1893) studied trauma during the second half of his career, from the later 1870s through to his death in the early 1890s.
