Sir Charles Scott Sherrington (27 November 1857 – 4 March 1952) was a British neurophysiologist and academic. His experimental research established many aspects of contemporary neuroscience, including the concept of the spinal reflex as a system involving connected neurons (the "neuron doctrine"), and how signal transmission between neurons can be potentiated or depotentiated. Sherrington himself coined the word "synapse" to define the connection between two neurons. His book The Integrative Action of the Nervous System (1906) is a synthesis of this work, in recognition of which he was awarded the Nobel Prize in Physiology or Medicine in 1932 (along with Edgar Adrian).

In addition to his work in physiology, Sherrington did research in histology, bacteriology, and pathology. He was president of the Royal Society in the early 1920s.

Early life Official biographies claim Charles Scott Sherrington was born in Islington, London, England, on 27 November 1857, and that he was the son of James Norton Sherrington, a country doctor, and his wife, Anne Thurtell. However, James Norton Sherrington was an ironmonger and artist's colourman in Great Yarmouth, not a doctor, and died in Yarmouth in 1848, nearly 9 years before Charles was born.GRO index: 1848 Dec, Yarmouth 13, 258Will of James Norton Sherrington, proved at London 5 March 1849, National Archives Catalogue Reference:Prob 11/2090, image 171

In the 1861 census, Charles is recorded as Charles Scott (boarder, 4, born India) with Anne Sherrington (widow) as the head and Caleb Rose (visitor, married, surgeon). He was brought up in this household with Caleb recorded as head in 1871, although Anne and Caleb did not marry until after the death of his wife in 1880.GRO marriages index: 1880 Dec, Ipswich 4a, 1377

The relationship between Charles and his childhood family is unknown. During the 1860s the whole family moved to Anglesea Road, Ipswich, reputedly because London exacerbated Caleb Rose's tendency to asthma.

Sherrington's origins have been discussed in several published sources: Chris Moss and Susan Hunter, in the Journal of Medical Biography of January 2018, presented an article discussing the potential origins of Charles Sherrington, i.e. whether he was born in India of unknown parents, or was the illegitimate child of Caleb Rose and Anne Sherrington.

Erling Norrby, PhD, in Nobel Prizes and Notable Discoveries (2016) observed: "His family origin apparently is not properly given in his official biography. Considering that motherhood is a matter of fact and fatherhood a matter of opinion, it can be noted that his father was not James Norton Sherrington, from whom his family name was derived. Charles was born 9 years after the death of his presumed father. Instead, Charles and his two brothers were the illegitimate sons of Caleb Rose, a highly regarded Ipswich surgeon."Nobel Prizes and Notable Discoveries, Erling Norrby, The Royal Swedish Academy of Sciences, Sweden, World Scientific Publishing, 2016, p. 24

In Ipswich Town: A History, Susan Gardiner writes: "George and William Sherrington, along with their older brother, Charles, were almost certainly the illegitimate sons of Anne Brookes, née Thurtell, and Caleb Rose, a leading surgeon from Ipswich, with whom she was living in College Road, Islington at the time that all three boys were born. No father was named in the baptism register of St James' Church, Clerkenwell, and there is no official record of the registration of any of their births. It was claimed they were the sons of a country doctor, James Norton Sherrington. However, it was with Caleb Rose that Anne and the three Sherrington boys moved to Anglesea Road, Ipswich in 1860, and the couple were married in 1880 after Caleb's first wife had died."Ipswich Town: A History, Susan Gardiner, Amberley Publishing, 2009, Chapter 2: Origins.

Judith Swazey, in Reflexes and Motor Integration: Sherrington's Concept of Integrative Action (1969), quotes Charles Scott Sherrington's son, Carr Sherrington: "James N. Sherrington was always called Mr. and I have no knowledge that he was a Dr. either in law or in medicine... [He] was mainly interested in art and was a personal friend of J. B. Crone and other painters."Reflexes and Motor Integration: Sherrington's Concept of Integrative Action, Judith P. Swazey, Harvard University Press, 1969, p. 211

Caleb Rose was noteworthy as both a classical scholar and an archaeologist. At the family's Edgehill House in Ipswich one could find a fine selection of paintings, books, and geological specimens. Through Rose's interest in the Norwich School of Painters, Sherrington gained a love of art. Intellectuals frequented the house regularly. It was this environment that fostered Sherrington's academic sense of wonder. Even before matriculation, the young Sherrington had read Johannes Müller's Elements of Physiology. The book was given to him by Caleb Rose.

Sherrington entered Ipswich School in 1871. Thomas Ashe, a famous English poet, taught at the school. Ashe served as an inspiration to Sherrington, instilling a love of classics and the desire to travel.

Rose had pushed Sherrington towards medicine. Sherrington first began to study with the Royal College of Surgeons of England. He also sought to study at Cambridge, but a bank failure had devastated the family's finances. Sherrington elected to enroll at St Thomas' Hospital in September 1876 as a "perpetual pupil". He did so in order to allow his two younger brothers to do so ahead of him. The two studied law there. Medical studies at St. Thomas's Hospital were intertwined with studies at Gonville and Caius College, Cambridge. Physiology was Sherrington's chosen major at Cambridge. There, he studied under the "father of British physiology," Sir Michael Foster.

Sherrington played football for his grammar school, and for Ipswich Town Football Club; he played rugby for St. Thomas's, was on the rowing team at Oxford. During June 1875, Sherrington passed his preliminary examination in general education at the Royal College of Surgeons of England (RCS). This preliminary exam was required for Fellowship, and also exempted him from a similar exam for the Membership. In April 1878, he passed his Primary Examination for the Membership of the RCS, and twelve months later the Primary for Fellowship.

In October 1879, Sherrington entered Cambridge as a non-collegiate student. The following year he entered Gonville and Caius College. Sherrington was a first-rate student. In June 1881, he took Part I in the Natural Sciences Tripos (NST) and was awarded a Starred first in physiology; there were nine candidates in all (eight men, one woman), of whom five gained First-class honours (Firsts); in June 1883, in Part II of the NST, he also gained a First, alongside William Bateson.University of Cambridge Calendar, 1894-95, p. 330 Walter Holbrook Gaskell, one of Sherrington's tutors, informed him in November 1881 that he had earned the highest marks for his year in botany, human anatomy, and physiology; second in zoology; and highest overall. John Newport Langley was Sherrington's other tutor. The two were interested in how anatomical structure is expressed in physiological function.

Sherrington earned his Membership of the Royal College of Surgeons on 4 August 1884. In 1885, he obtained a First Class in the Natural Science Tripos with the mark of distinction. In the same year, Sherrington earned the degree of M.B., Bachelor of Medicine and Surgery from Cambridge. In 1886, Sherrington added the title of L.R.C.P., Licentiate of the Royal College of Physicians.

Seventh International Medical Congress

The 7th International Medical Congress was held in London in 1881. It was at this conference that Sherrington began his work in neurological research. At the conference, controversy broke out. Friedrich Goltz of Strasbourg argued that localized function in the cortex did not exist. Goltz came to this conclusion after observing dogs who had parts of their brains removed. David Ferrier, who became a hero of Sherrington's, disagreed. Ferrier maintained that there was localization of function in the brain. Ferrier's strongest evidence was a monkey who suffered from hemiplegia, paralysis affecting one side of the body only, after a cerebral lesion.

A committee, including Langley, was set up to investigate. Both the dog and the monkey were chloroformed. The right hemisphere of the dog was delivered to Cambridge for examination. Sherrington performed a histological examination of the hemisphere, acting as a junior colleague to Langley. In 1884, Langley and Sherrington reported on their findings in a paper. The paper was the first for Sherrington.

Travel In the winter of 1884–1885, Sherrington left England for Strasbourg. There, he worked with Goltz. Goltz, like many others, positively influenced Sherrington. Sherrington later said of Goltz that: "[h]e taught one that in all things only the best is good enough."

A case of asiatic cholera had broken out in Spain in 1885. A Spanish doctor claimed to have produced a vaccine to fight the outbreak. Under the auspices of Cambridge University, the Royal Society of London, and the Association for Research in Medicine, a group was put together to travel to Spain to investigate. C.S. Roy, J. Graham Brown, and Sherrington formed the group. Roy was Sherrington's friend and the newly elected professor of pathology at Cambridge. As the three travelled to Toledo, Sherrington was skeptical of the Spanish doctor. Upon returning, the three presented a report to the Royal Society. The report discredited the Spaniard's claim.

Sherrington did not meet Santiago Ramón y Cajal on this trip. While Sherrington and his group remained in Toledo, Cajal was hundreds of miles away in Zaragoza. Later that year, Sherrington travelled to Rudolf Virchow in Berlin to inspect the cholera specimens he procured in Spain. Virchow later on sent Sherrington to Robert Koch for a six-week course in technique. Sherrington ended up staying with Koch for a year to do research in bacteriology. Under these two, Sherrington parted with a good foundation in physiology, morphology, histology, and pathology. During this period he may have also studied with Waldeyer and Zuntz.

In 1886, Sherrington went to Italy to again investigate a cholera outbreak. While in Italy, Sherrington spent much time in art galleries. It was in this country that Sherrington's love for rare books became an obsession.

Career

In 1891, Sherrington was appointed as superintendent of the Brown Institute for Advanced Physiological and Pathological Research of the University of London, a center for human and animal physiological and pathological research. Sherrington succeeded Sir Victor Alexander Haden Horsley. There, Sherrington worked on segmental distribution of the spinal dorsal and ventral roots, he mapped the sensory dermatomes, and in 1892 discovered that muscle spindles initiated the stretch reflex. The institute allowed Sherrington to study many animals, both small and large. The Brown Institute had enough space to work with large primates such as apes. Sherrington's first job of full professorship came with his appointment as Holt Professor of Physiology at Liverpool in 1895, succeeding Francis Gotch. With his appointment to the Holt Chair, Sherrington ended his active work in pathology. Working on cats, dogs, monkeys, and apes that had been bereaved of their cerebral hemispheres, he found that reflexes must be considered integrated activities of the total organism, not just the result of activities of the so-called reflex-arcs, a concept then generally accepted. There he continued his work on reflexes and reciprocal innervation. His papers on the subject were synthesized into the Croonian lecture of 1897.
