William Farr

William FarrCB(30 November 1807 – 14 April 1883) was a Britishepidemiologist,regarded as one of the founders ofmedical statistics.

Early life[edit]

William Farr was born inKenley, Shropshire,to poor parents. He was effectively adopted by a local squire, Joseph Pryce, when Farr and his family moved toDorrington.In 1826 he took a job as a dresser (surgeon's assistant) in theSalop InfirmaryinShrewsburyand served a nominal apprenticeship to anapothecary.Pryce died in November 1828, and left Farr £500 (equivalent to £54,100 in 2023), which allowed him to study medicine inFranceandSwitzerland.[1]In Paris he heardPierre Charles Alexandre Louislecture.[2]

Farr returned to England in 1831 and continued his studies atUniversity College London,qualifying as a licentiate of theSociety of Apothecariesin March 1832. He married in 1833 and started a medical practice inFitzroy Square,London. He became involved in medical journalism and statistics.[1]

General Register Office[edit]

In 1837 theGeneral Register Office(GRO) took on the responsibility for theUnited Kingdom Census 1841.Farr was hired there, initially on a temporary basis to handle data fromvital registration.[1][3]Then, with a recommendation fromEdwin Chadwickand backing fromNeil Arnott,Farr secured another post in the GRO as the first compiler of scientific abstracts (i.e. a statistician).[4][5]Chadwick and Farr had an agenda, demography aimed atpublic health,and the support of the initial Registrar GeneralThomas Henry Lister.Lister worked with Farr on the census design, to forward the programme.[6]

Farr was responsible for the collection of official medical statistics in England and Wales. His most important contribution was to set up a system for routinely recording the causes of death. For example, for the first time it allowed themortality ratesof different occupations to be compared.

Learned societies and associations[edit]

In 1839, Farr joined theStatistical Society,in which he played an active part as treasurer, vice-president and president over the years. In 1855 he was electedFellow of the Royal Society.[7]He was involved in theSocial Science Associationfrom its foundation in 1857,[8]taking part in its Quarantine Committee and Committee on Trades' Societies and Strikes.[9]

Law of epidemics[edit]

Main article:Farr's laws

In 1840, Farr submitted a letter to theAnnual Report of the Registrar General of Births, Deaths and Marriages in England.In that letter, he applied mathematics to the records of deaths during a recentsmallpoxepidemic, proposing that:

"If the latent cause of epidemics cannot be discovered, the mode in which it operates may be investigated. The laws of its action may be determined by observation, as well as the circumstances in which epidemics arise, or by which they may be controlled."[10]

He showed that during the smallpox epidemic, a plot of the number of deaths per quarter followed a roughly bell-shaped or "normal curve",[11][12]and that recent epidemics of other diseases had followed a similar pattern.[13]

Research on cholera[edit]

There was a major outbreak ofcholerain London in 1849 which killed around 15,000 people. Early industrialisation had made London the most populous city in the world at the time, and theRiver Thameswas heavily polluted with untreated sewage. Farr subscribed to the conventional theory that cholera was carried by polluted air rather than water – themiasmic theory.In addition, through his analysis of several variables and their association with death from cholera, Farr held the belief that elevation was the major contributor to the occurrence of the disease.[14][15]He also presented how topographical features are able to prevent certain diseases similarly to immunization.[16]

During the 1853-54 epidemic, Farr gathered more statistical evidence.[17]During focused study of the1854 Broad Street cholera outbreak,the physicianJohn Snowused data supplied by the GRO[18]and applied the (now accepted) mechanism for transmission he had proposed in 1849:[19]people were infected by swallowing something, and it multiplied in theintestines.Snow also examined mortality statistics compiled by the GRO for people supplied with water from two companies in South London – the Southwark & Vauxhall Company (which drew contaminated water from low in the Thames basin) and the Lambeth Water Company (which drew cleaner water from further up the Thames) – and found Southwark & Vauxhall customers were especially likely to suffer.[20][21] Farr took part in theGeneral Board of Health's 1854 Committee for Scientific Enquiries. The conventional explanation for cholera was stillmultifactorial;Snow's view of cholera as solely caused by apathogenwas not accepted, though his evidence was taken seriously. Farr's research was detailed and showed an inverse correlation of mortality and elevation.[22]

There was a further epidemic in 1866, by which time Snow had died, and Farr had accepted Snow's explanation. He produced a monograph which showed that mortality was extremely high for people who drew their water from the Old Ford Reservoir in East London. Farr's work was then considered conclusive.

Later life[edit]

In 1858, he performed a study on the correlation of health and marriage condition, and found that health decreases from the married to the unmarried to the widowed.[23]In the period 1857–9 the Office ordered adifference engine,a model designed by Swedish followers ofCharles Babbage.[24]The intended application was the "British Life Table".[25]

William Farr, about 1870

In 1862 Farr was paid £300 (equivalent to £35,400 in 2023) for producing a report on theMetropolitan PoliceSuperannuation Fund, an early pension provision for that organisation.[26]He also served as a commissioner in the 1871 census, retiring from the General Register Office in 1879 after he was not given the post ofRegistrar General,the position going to Sir Brydges Henniker.[27]The same year, Farr received as honours aCompanionship of the Bathand the Gold Medal of theBritish Medical Associationfor his work in the field ofbiostatistics.[1]

In his last years, Farr's approach had become obsolescent.Bacteriologyhad changed the face of the medical issues, and statistics became an increasingly mathematic tool. Medical reformers, too, changed approach, expecting less from legislation and central government.[28]

Farr died aged 75 at his home inMaida Vale,London, and was buried in the churchyard at Holy Trinity,Bromley Common.[1]

Works[edit]

In 1837 Farr wrote the chapter "Vital Statistics" forJohn Ramsey McCulloch'sStatistical Account of the British Empire.In January 1837 he established theBritish Annals of Medicine, Pharmacy, Vital Statistics, and General Science,discontinued in August of that year. He revised a book ofJames Fernandez Clarkeontuberculosis.[29]

Farr exploited his GRO post compiling abstracts in a way that went beyond the original job description. In so doing he applied the techniques of the EnglishactuaryBenjamin Gompertz(theGompertz curve), and the closely allied statistical "law of mortality" of his fellow actuaryThomas Rowe Edmonds.Farr, by relying on the existing mathematical model of mortality, could usedata samplingto cut back the required computation.[30]From the GRO data he constructed a series of nationallife tables.[31]

The theory ofzymotic diseasewas Farr's contribution to the debate onaetiology.He identified urbanisation andpopulation densityas public health issues.[32]In terms ofnosologyhe classed epidemic, endemic and contagious diseases as "zymotic", seen as diseases of filth and overcrowding.[33]

A selection of his statistical writings was published in 1885, edited by Noël Humphreys.[27]

In drama[edit]

In "The Sewer King",an episode in the 2003 British television documentary seriesSeven Wonders of the Industrial World,Farr was played byNorman Lovett.[34]

Family[edit]

Farr's first wife, whom he married in 1833, had the surname Langford; she died oftuberculosisin 1837.[35]He married Mary Elizabeth Whittal in 1842, and they had eight children. In 1880 a public testimonial was collected to provide for his daughters after he lost money through unwise investments.[1]

One daughter, Henrietta, was married to painter and illustratorHenry Marriott Paget,the older brother of illustratorsSidneyandWalter Paget.Another daughter,Florence Farr,was also a painter and artist and a model of many famousart decoworks of art. The Pagets as well as the Farr sisters lived and worked inBedford Park,the famous artist's colony in West London.

Recognition[edit]

Farr's name features on the Frieze of theLondon School of Hygiene & Tropical Medicine.Twenty-three names of public health and tropical medicine pioneers were chosen to appear on the School building in Keppel Street when it was constructed in 1926.[36]

In 1884,Farriolla,which is agenusoffungiin theAscomycotaphylum, was named in William Farr's honour.[37]

It appears probable, however, that the small-pox increases at an accelerated and then a retarded rate; that it declines first at a slightly accelerated, and at a rapidly accelerated, and lastly at a retarded rate, until the disease attains the minimum intensity, and remains stationary."

Though he gives no equation of the form of the curve, it is quite obviously the normal curve of error."

They exhibit the same regularity, but the laws which govern their course will be more conveniently discussed when the abstract of the observations has been extended over another year."
