Robert Graves, Marshall Hall, and reflex action in 1837

In several issues of the London Medical Gazette during June-July of 1837 there was an interchange of letters between Robert Graves, Regius Professor of the Institutes of Medicine at Trinity College, Dublin, and the London physician and experimental physiologist Marshall Hall, often considered the discoverer of the phenomenon of reflex activity. Graves asserted that he, rather than Hall, was the originator of the idea of reflex action as a disease mechanism. Hall rejected that assertion and, after exchange of some verbal "pleasantries," began a tirade about a somewhat different, although not unrelated issue into which the journal editor interjected some not exactly dispassionate comments. Graves soon let the matter of priority lapse, and Hall continued his war with the Council of the Royal Society, but examination of the contemporary and earlier literature suggests that Graves probably was correct, by a narrow time margin, in relation of his claim for priority in using the concept of reflex action in explaining neurological disease mechanisms (not a claim for discovering reflex action), that Hall had used the phrase "reflex action" earlier than Graves, and that others before Hall had gone a long way in studying reflex mechanisms, although Hall's writings had familiarized the medical profession with the concept.
