Early on in the program, we took a class day trip to the Palace of Versailles. We took a guided tour of the palace itself and then got to spend time later on in the gardens. During the French Revolution, Versailles was an extension of the Hotel des Invalides due to high demand of care. About 6,000 people asked to be treated there, but the Hotel had a maximum capacity of 6,000. PTSD was not officially named yet during the French Revolution, but psychiatrists starting noticing it in soldiers. A French psychiatrist, Philippe Pinel, had a lot of patients who exhibited symptoms of PTSD and called it cardiorespiratory neurosis. He documented the first accurate description of war neuroses in his treatise called Nosographie Philosophique (Crocq & Crocq, 2000).
