Marshall Hall FRS (18 February 1790 – 11 August 1857) was an English physician, physiologist and early neurologist.

His name is attached to the theory of reflex arc mediated by the spinal cord, to a method of resuscitation of drowned people, and to the elucidation of function of capillary vessels.

J. Blanchard's academy at Nottingham, he entered a chemists shop at Newark-on-Trent, and in 1809 began to study medicine at Edinburgh University.

This appointment he resigned after two years, when he visited Paris and its medical schools, and, on a walking tour, those also of Berlin and Göttingen.

In the following year he read before the Royal Society a paper On the Inverse Ratio which Subsists between Respiration and Irritability in the Animal Kingdom.

The reflex function excited great attention on the continent of Europe, though in England some of his papers were refused publication by the Royal Society.

Hall thus became the authority on the multiform deranged states of health referable to an abnormal condition of the nervous system, and he gained a large practice.

[6] In Asphyxia, its Rationale and its Remedy (1856), Hall developed a technique for preventing victims of drowning by freeing their respiratory airway and by providing immediate ventilation, as the initial steps in resuscitation.

I cannot say less, and more fearful words cannot be written.He believed that every slaveholder had a "guilt of sin against God, and of sin against his fellow-man"[13] and insisted that there was no credible hypothesis to rationally support white supremacy, stating: No hypothesis of difference of origin, race or species, or by whatever other name it may be named, can take from the African people that which they have nobly earned for themselves, a well-founded reputation – for gratitude, fidelity, loyalty, of all which truthful biography and history record innumerable instances ; – for ability in commerce, in the useful arts, in agriculture, of which living instances abound ; – for mathematics ; for music and eloquence ; and for military genius, and political ability and integrity.
