There are many general and specialized biographies about him, the result being that a new text is unexpected or would likely amount to plagiarism. However, part of the duties for Charcot's medical professorship have not, to date, been studied at all. This article will focus on the role of Charcot as a member of doctorate juries and, in particular, as the president of these juries. I have reviewed around 12,500 theses one by one. These were defended at the Paris medical school from 1862, Charcot's first year as an <i>agrégé</i> (assistant professor), to his death in 1893. Among the theses, I have selected all of those that discuss neuropsychiatry in the broadest terms (3,663). I have paid particular attention to all of those for which Charcot was part of the jury. This involves 608 theses. All of the data were entered in a database (Filemaker) to facilitate identifying those theses corresponding to one or more of the criteria. Statistical comparisons were then carried out (Excel spreadsheet). In addition to these results, brief individualized surveys were conducted on theses selected for their representativeness, either for the subject matter (multiple sclerosis, aphasia, tabes, general paralysis, etc.) or for specific criteria (foreigners, women, etc.), but all of the theses were defended before a jury that included Charcot. This makes it possible to track how the areas of study in the medical world changed over time, and particularly those of Charcot. The juries Charcot was obliged to be a part of, without any particular ties to the candidate and/or any involvement in the selection and supervision of the work, must be differentiated from the thesis juries for his students. In the latter case, the thesis subjects were most often linked to Charcot's researches. Providing a thesis subject was motivated, in certain cases, by the desire to disseminate new data in the medical profession, not only by dint of the theses themselves but also through the reports that the medical press published regularly (e.g. the diagnosis of various types of shaking) and through the commercial publication of these data, in some cases with a preface by Charcot. In other cases, the thesis was a step in the long process of developing a theory (hysteria). Or it led to a flowering of new ideas, insufficiently proven, which Charcot would only cover in his <i>Lessons</i> once there was convincing confirmation (amyotrophy). This rich cornucopia gives rise to certain neglected nuggets, as well as works that have entered the classical corpus-for example, the theses of Léopold Ordenstein, Ivan Poumeau, Isaac Bruhl, Albert Gombault, and Pierre Janet.</p>","PeriodicalId":49997,"journal":{"name":"Journal of the History of the Neurosciences","volume":" ","pages":"185-205"},"PeriodicalIF":0.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141248708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

His lectures, which also postulated the independence of ideas from words, were to resonate beyond aphasia specialists, and particularly with alienists.

However, his pursuit of hysteria, the most prevalent diagnosis in his hospital clinic, yielded no anatomical lesion to account for hysteria's plethora of somatic disorders assumed due to a purely functional or <i>dynamic</i> lesion in the cerebral cortex. This led Charcot to turn his attention to the psychology of hysteria. Taking advantage of institutional reforms at the Salpêtrière-notably, the establishment of his professorship in nervous diseases-Charcot from the early 1880s focused his teaching increasingly on case histories of hysteria in male as well as female patients. Already renown for his earlier dramatic public lessons on female hysteria, his lessons of the 1880s, of which two volumes were published at the end of the decade, elaborated the issue of psychology in terms of altered states of patient's suggestibility. By the decade's end, Charcot's worldwide reputation rested on the prospects of this work as acknowledged by numerous students, notably medical psychologists Pierre Janet and Sigmund Freud. Yet Charcot's views remained sketchy. They were discussed at length in his unpublished notes for a lesson intended for May 1893, just a few months before his sudden death. His unpublished notes reveal a detailed case for dreams as illustrating a psychological mechanism underlying hysteria in a 17-year-old Paris artisan.

This narrative is often used by biologists and physicians as a reference point. This article shows that the use of the hagiographic register faces limitations. In particular, it obscures points of interest from Charcot's texts on ALS, such as the epistemological and ontological implications of scientific plurality in medicine. Although Charcot recognized the importance of scientific plurality in medicine, he prioritized the approaches and conferred the most important epistemic authority on clinical and pathological observations. In his view, animal modeling remains secondary to the understanding of disease. The concept of ALS and its diagnostic operability are the result of symptoms and lesions. By studying the past, we can highlight the specific features of the present. Today, although the ALS concept retains its diagnostic and clinical relevance, it is increasingly called into question in etiological and mechanistic research.
