The development of neurology as an independent discipline in the mid-19th century was considerably influenced by the almost simultaneous foundation of the Charcot School at the Salpêtrière Hospital in Paris and the National Hospital for the Paralysed and Epileptic and it's School at Queen Square in London in the 1860's. We have reviewed the early interactions between Charcot's school and the leading neurologists at the National Hospital and also discussed their neurological antecedents and subsequent links up to the outbreak of World War 1 in 1914. Earlier interactions involved Trousseau and Duchenne in France and Graves, Todd, Laycock and Allbutt in Britain. The French Brown–Séquard was one of the first two physicians appointed to the National Hospital. Charcot was a frequent visitor to Britain culminating in his influential role in the 1881 International Medical Congress in London. He first suggested the terms “Parkinson's Disease” and “Jacksonian Epilepsy”. He attracted numerous British visitors to Paris and his studies of hysteria were influenced by Laycock, Todd and Russell Reynolds. Hughlings Jackson drew upon the anatomical studies of Gratiolet in his interactions with Broca and Charcot which influenced French views on aphasia, epilepsy and cortical localisation. Ball, an Englishman, was the first Professor of mental and brain diseases in Paris in 1877. Bruce in Edinburgh and Kinnier Wilson in London both maintained frequent contacts with Paris, where the latter first presented his studies of hepatolenticular degeneration in 1912. The Entente Cordiale of 1904 led to further interactions with the leading role of the French and British physicians Raymond and Duckworth. Two outstanding British women, Elizabeth Garrett and Blanche Edwards, qualified in Medicine in Paris with neurological interests. Our review emphasises the constructive influence of the French and British Schools on each other and thus on the development of neurology. The French influence was primarily the establishment of the anatomo-clinical method and the use of photographic illustrations in publications. The British School influence was its Clinical Assessment Skills and scientific studies of newly recognised diseases and concepts and its early development of neurosurgery.
