Henry Head

Sir Henry Head, FRS[1] (4 August 1861 – 8 October 1940) was an English neurologist who conducted pioneering work into the somatosensory system and sensory nerves.

[5] Early in his childhood, Head's family moved from Stoke Newington to Stamford Hill where they inhabited a house decorated for them by William Morris.

"[1] This was the man, he said, to whom he "[owed] the fact that [he] was firmly grounded in the elements of natural science at an age when boys at an ordinary school in my day were ignorant of its existence."

[3] Having gained a place at Trinity College, Cambridge, the budding scientist decided to forgo his final term at Charterhouse in favour of foreign study.

Through his mother he had gained a love of literature and this would do much to direct his choice of acquaintances in later life when he was to become firm friends with authors (most notably to Thomas Hardy) and a mentor to the poet Siegfried Sassoon.

[3] Returning to England in time to go up to Cambridge where he made friends and acquaintances who would become distinguished in their own rights: D'Arcy Thompson, W.R Sorley, A.N Whitehead and William Bateson were among them.

[3] Head left Cambridge with a first class degree in both parts of the Natural Science Tripos,[6] and decided to travel abroad once more, this time to inspect laboratories in Germany.

[3] Head remained in Prague for two years, expanding his knowledge and his interests before returning to Cambridge to complete courses in anatomy and physiology and joining University College Hospital, London, where he was to qualify as a doctor in 1890.

His earlier experiences in Prague had created an interest in the physiology of respiration and he was later attracted to the Victoria Hospital for Diseases of the Chest, where he became a house physician.

I then began to investigate the distribution of herpes zoster in the hope that a skin lesion which was notoriously of nervous origin might throw some light on the meaning and significance of the tender areas in visceral disease....

Head first showed his talent for teaching at the age of 21 when he addressed the Stoke Newington Mutual Instruction Society at the Friends Meeting House, Park Street, on the fertilization of plants.

He told me to buy Gee's little book on percussion, and kindly taught me throughout our journeys about physical signs, much to the annoyance of our fellow travellers; indeed in his characteristic keenness he spoke so loudly that as we walked to the hospital from St. Mary's station people on the other side of the wide Whitechapel Road would turn to look at us.

Almost twenty years previously he had written in his diary: "Medical education in England suffers from the fact that the great hospitals are manned by practitioners of medicine who sometimes teach, instead of by professors of that science who occasionally practise.

In his poem "Long Ago I used to Pray", for example, he takes on the perspective of a woman yearning for 'the fierce joy of motherhood' and presents a sympathetic view of her plight.

As Holmes writes, "in his later years her philosophical outlook, her joy in life and her encouragement helped him to bear an illness which otherwise would have been an intolerable fate to one of his active mind and body.

He first looked at sensation through physiological eyes, using his training from Prague and Cambridge, but he soon became aware that psychological factors also had a major part to play.

Campbell enabled him to demonstrate the zones of skin affected by disease and from this he could chart the cutaneous distribution of different fibres originating from cells of each ganglion and reaching the corresponding segment of the spinal cord.

This led Head to conclude that irradiation of abnormal afferent impulses produces a state of excessive irritability in the grey matter of the dorsal horn at the level which they enter it.

[13] Head also became increasingly interested in the mental changes brought on by visceral disease and he based his Goulstonian Lectures before the Royal College of Physicians on this topic.

[1] Throughout the many arduous and time-consuming experiments of this period, Head is described as maintaining his energy and enthusiasm with his vivid imagination suggesting new lines of thought for every problem.

It had soon become obvious that external distractions had an adverse effect on results and so Head sat every weekend with his eyes closed as Rivers charted the areas of sensitivity.

During the First World War his studies continued as he worked with G. Riddoch to test reflex activities of isolated portions of spines subjected to gunshot wounds.

These volumes were devoted not only to the clinical or symptomatic aspects of disturbances of speech, but were also an attempt to investigate the psychical processes concerned therein, and the physiological integrations necessary for the comprehension and expression of ideas as language.

The war prompted Head to write poetry which was later published in 1919 in the volume Destroyers and Other Verses, it also brought him together with fellow poet Siegfried Sassoon, who was under Rivers's care.

[14] After Rivers's premature death in 1922, Head adopted the mentoring role that he had once occupied, comforting a distraught Sassoon with remembrances of their friend and reassurances that nothing mattered except life.

It was no unusual thing to hear him in the course of one evening discourse on topics so various as: the influence of reasoning upon Goethe and Mozart, types of apprehension in listeners to symphonic music, sensations while looping the loop (he was over 60 when he did so), the painting of Guardi, 'co-ordination' in a star golfer, Ninon de Lenclos, Conrad as a narrator (Sir Henry was far the ablest literary critic I have ever known), religious ecstasy, the relation of art and science, the social customs of Melanesia.

With his excellent general health he well knew what he had to face – long years of steadily increasing physical disablement, with his mind unimpaired except in its capacity for continuous effort; in the grip of a relentless foe which medical science could not restrain.

Essentially an individualist, whilst dependent upon friends and kindred spirits, he succeeded in keeping alive his wide interests and, through the attraction of his personality, the contacts which were necessary to him.

Science, literature, music, human affairs, all retained their accustomed importance, although in a increasingly restricted sense as the enemy, whom he could not conquer, but who never defeated his active mind, encircled him ever more tightly.

His final wish was to aid 'the purpose of the advancement in England of the science of medicine in the widest sense' with the Royal Society as residuary legatee.
