[The first thing Pearson could remember] was sitting in a high chair sucking his thumb. Someone told him to stop sucking it, and added that unless he did so, the thumb would wither away. He put his two thumbs together and looked at them for a long time. “They look alike to me,” he said to himself. “I can’t see that the thumb I suck is any smaller than the other. I wonder if she could be lying to me.” Here in this simple story we have rejection of constituted authority, faith in his own interpretation of the meaning of observed data, and finally, imputation of moral obliquity to a person whose judgement differed from his own. These characteristics were prominent throughout his entire career. Walker (1958 & -78)
Karl Pearson was born in London on March 27th 1857 into an upper-middle class family, his father a barrister. He read mathematics at Cambridge University, where Maxwell, Cayley and Stokes were the luminaries. He had the best of coaches, Routh, and came through the examinations as third wrangler. This brought him a fellowship and, for some years, financial freedom to travel and to pursue very diverse interests. He qualified as a barrister and studied social, philosophical, literary and historical questions, turning himself into a German Late Romantic. Pearson developed his own view of man’s place in a post-Christian world, expressing his ideas in a novel and play as well as in essays—some of these appeared in the Ethic of Freethought (1888) and the Chances of Death and Other Studies of Evolution (1897). Pearson founded the Men and Women’s Club and in 1890 married a fellow-member Maria Sharpe. They had three children; the son Egon Sharpe Pearson also became an important statistician.
In 1884 Pearson became Professor of Applied Mathematics and Mechanics at University College London (UCL). Mechanics and the theory of elasticity—and later biometry—eventually crowded out other pursuits. Pearson took on the task of completing Todhunter’s History of the Theory of Elasticity and Clifford’s Common Sense of the Exact Sciences. The Elasticity is a very detailed internal history of Pearson’s own specialism. The book by Clifford, the first holder of the UCL chair, explains the basic principles of mathematics in a non-technical way. Pearson not only edited what Clifford had written but contributed about a third of the final text Pearson’s ideas for the reform of mechanics were close to those of Mach and he developed them further in the Grammar of Science (1892). This presented the scientific method as “the orderly classification of facts followed by the recognition of their relationship and recurring sequences.” His achievements as an applied mathematician were recognised when he was elected to the Royal Society in 1896.
Between 1891 and -94 Pearson gave four series of lectures at Gresham College. The first series provided the basis for the Grammar. The later lectures treated statistics. Pearson had developed a new interest to which he would devote his greatest efforts. With W. F. R. Weldon, professor of zoology at UCL, he founded biometry. Weldon had come to the view that “the problem of animal evolution is essentially a statistical problem” and was applying Francis Galton’s (1822-1911) statistical methods, including correlation. Pearson joined in, developing new techniques and eventually a new theory of statistics. Over the next ten years Pearson made his most important contributions to statistics, including the method of moments, the Pearson system of curves, correlation and the chi-squared test. Pearson realised that the methods he had devised for biometry had other uses and he and his collaborators applied them to all manner of subjects. The most important of the early collaborators was G. Udny Yule, whose applied interests were in social policy and medicine. By the end of the nineteenth century there was an embryonic mathematical statistics community extending to non-biometricians such as F. Y. Edgeworth and W. F. Sheppard.
In 1901 Pearson, Weldon and Galton founded Biometrika, a “Journal for the Statistical Study of Biological Problems”. The mission was controversial. Following the “rediscovery” of Mendel, William Bateson (1861-1926) argued that the statistical study was pointless while Pearson thought Mendel’s account covered only a few special cases. In 1903 Pearson established the Biometric Laboratory. This drew visitors from all over, including W. S. Gosset (‘Student’) from Guinness in Dublin and the biologist Raymond Pearl and the economist H. L. Moore from the United States. (American economists, like Moore and Irving Fisher, thought more of Pearson than their British counterparts—see below) As well as research in theoretical and applied statistics, much effort went into constructing statistical tables. In 1907 Pearson took over a research unit founded by Galton and reconstituted it as the Francis Galton Laboratory of National Eugenics. The laboratory researched human pedigrees but it also produced controversial reports on the role of inherited and environmental factors in tuberculosis, alcoholism and insanity. Pearson saw his role in eugenics as providing the scientific foundations and he addressed other experts rather than the public directly.
In 1911 a bequest from Galton led to the establishing of a chair of Eugenics and a Department of Applied Statistics at University College. Pearson was no longer responsible for applied mathematics. After the 1914-18 war statistics continued to flourish and the department went on attracting talents, such as Neyman and Wishart, but Pearson was no longer producing influential new ideas. By the later 20s R. A. Fisher was replacing him as the dominant influence on the subject. Some of Fisher’s most important contributions were corrections to Pearson’s work and relations between the men were bad from around 1917. Pearson retired in 1933 but he continued to write and, with his son E. S. Pearson, to edit Biometrika. He died on April 27th 1936.
Sources E. S. Pearson’s biography is the major source. It is thorough and fair-minded, though inevitably dated. For the early Pearson it has now been surpassed by Porter (2004). The newer biography focuses on the making of the statistician and does not try to cover in the same detail what Pearson did when his career was under way.

Karl Pearson was a great teacher. For fifty years he taught at University College; his subjects were applied mathematics, astronomy and statistics. For nearly forty years he almost monopolised the teaching of statistics in Britain and many prominent statisticians studied with him. Some went as undergraduates, some as fledgling members of staff and some as visitors; the modern PhD system was established only towards the end of Pearson’s career and he was never part of it. The following were among those who studied with him—the reference, unless otherwise stated, is to an obituary in the Journal of the Royal Statistical Society or, after 1948, to Series A of that journal: Burton H.

On Pearson’s death in 1936 and his centenary in 1957 the survivors reflected on him and his work. The reflections were generally more tempered than the reactions that Pearson generated in his life-time: “the man is a liar” wrote J. M. Keynes to W. Bateson in 1910 (Bateson Letters, John Innes Archives).
The Times obituary is available on the MacTutor Pearson page. Also available is an obituary for the Royal Society of Edinburgh by G. H. T. (presumably Godfrey Hilton Thomson (1881-1955) the statistical psychologist who contributed to Biometrika and was once offered a job by Pearson).
E. S. Pearson (1895-1980), Pearson’s son and his successor as head of the Department of Applied Statistics University College, London (UCL) and editor of Biometrika, wrote a full biography soon after his father’s death
This appeared as a book with the same title, published by Cambridge University Press, in 1938.
G. Udny Yule (1871-1951) was a student and eventually an assistant professor in Pearson’s department. Later he went his own way he and Pearson came to disagree about association, time series correlation, …. Yule’s appreciation of Pearson’s greatness and his flaws comes out in the two obituaries he wrote

Burton Camp, professor of mathematics at Wesleyan and President of the Institute of Mathematical Statistics in 1938, was an American visitor to Pearson’s laboratory during 1923-4; see Bellhouse (2011). He wrote on the occasion of Pearson’s retirement:

Raymond Pearl (1879-1940) attended Pearson’s lectures in 1905-6 and was once a co-editor of Biometrika. See Matthews (1995) and Bellhouse (2011) for his fluctuating relations with Pearson. From 1919 Pearl was a professor at Johns Hopkins. In his obituary he wrote warmly of Pearson’s influence on his generation.

William Palin Elderton (1877-1962) was a distinguished actuary. He first met Pearson in 1900 when he was training to be an actuary and was drawn into the University College statistical group. Elderton computed the first chi-square tables and in 1907 published an account of the Pearson curves (see below). His sister Ethel M. Elderton worked for Pearson for many years. In his obituary Elderton gave a balanced account of Pearson’s achievement and personality.

An anonymous reviewer of Fisher’s Statistical Methods for Research Workers (1925) used a quotation from Macaulay to describe Fisher’s relationship to Pearson: “just so we have heard a baby, mounted on the shoulders of its father, cry out, ‘how much taller I am than Papa!’” The reviewer was probably Major Greenwood. For more on Fisher and Pearson see A Guide to R. A. Fisher.
Major Greenwood (1880-1948) wrote the article that actually appeared in the DNB. Greenwood was an early follower of Pearson and became professor of medical statistics at the London School of Hygiene & Tropical Medicine: see Matthews (1995) for his relations with Pearson. In 1928 Greenwood wrote a memorandum on the state of medical statistics in which Pearson is compared with Newton but, as with Newton and the calculus, the Continentals had the better system!

J. B. S. Haldane (1892-1964), at UCL from 1933 first as professor of genetics then of biometry, compared Pearson to Columbus: following a false theory of heredity he discovered methods that proved indispensable for the study of evolution.

2007 was the Karl Pearson sesquicentenary (or sesquicentennial) and this was marked in various ways. There was a Karl Pearson sesquicentenary conference in London in March and a session (“Karl Pearson’s 150th birthday,” IPM78) at the conference of the International Statistical Institute in Lisbon in August; see below.
Pearson’s output was vast: Morant’s bibliography lists 648 publications and some of the projects like the Elasticity and the Galton biography were on the grandest scale.
G. M. Morant (1939) A Bibliography of the Statistical and other Writings of Karl Pearson, Cambridge University Press.
For the statistical papers—at least—Morant provides abstracts and cross-references. Most of the abstracts were written by B. L. Welch.
Most of Pearson’s articles are now accessible through JSTOR. However many of his contributions to Biometrika were unsigned editorials and material from lectures and the only infallible method for finding them on JSTOR is to go through volume by volume. Alternatively use the Morant bibliography.
The Pearson Papers at University College London has more than 16,000 letters, family papers and scientific manuscripts, including students’ notes on Pearson’s lectures and the records of the Men and Women’s Club. A catalogue is available:
A list of the papers and correspondence of Karl Pearson (1857-1936) held in the Manuscripts Room, University College London Library compiled by M Merrington, B Blundell, S Burrough, J Golden, J Hogarth (University College London, 1983).
The AIM25 listing contains a basic description of the collection.
Porter (2004) has a long list of archives, the ones he used in writing his book. There is also material at King’s College, Cambridge (Bradshaw Papers), in the University Library at Cambridge, at the Royal Society, the Royal Astronomical Society, Adelaide University Library, the Worshipful Company of Drapers, the American Philosophical Society Library and the Rockefeller Archive Center.
The books listed show Pearson’s range of interests: applied mathematics, philosophy of science, biometrics, eugenics, statistics, literature, linguistics and society. His novel and play are included for their biographical interest, not for their influence for they sank without trace; there are copies in the British Library but not, it seems, in the main UK university libraries. However reprints of them are now available. To see the mass and variety of the publications not included consult the Morant bibliography or the Karl Pearson entry in the COPAC catalogue. Over 300 articles can be found on JSTOR.
This selection omits several volumes of tables, tracts for computers and monographs on physical anthropology.

S. Pearson (1936, pp. 201ff)
The Exact Sciences are mathematics, pure and applied. The book was re-issued in 1946 with a laudatory preface by Bertrand Russell who had read it when he was fifteen.
Karl Pearson (ed.) (1886/93) A History of the Theory of Elasticity and of the Strength of Materials from Galilei to the Present Time by I. Todhunter, Vols I & II (II in two parts). Cambridge: University Press.
Pearson wrote more than half of this enormous work. He kept to Todhunter’s plan of summarising each contribution and the result is an encyclopedic treatise on the literature of elasticity organised chronologically rather than a history of science work of the modern kind. For discussion see Porter (2004, ch. 3) and E. S. Pearson (1936, p. 209 )
The first papers “endeavour to formulate the opinions which a rational being of to-day may hold with regard to the physical and intellectual worlds.” A second group “regards one or two phases of past thought and life from the Freethinker’s standpoint.” The final group “deals with great race problems”—socialism and the woman’s question. For discussion see Porter (2004, ch. 3) and E. S. Pearson (1936, pp. 198-206)
This positivist account of science was widely read in English and in translations. The second edition was enlarged to take account of Pearson’s mathematical studies in evolution. The third edition was conceived on an even larger scale but only the first (Physical) volume appeared. For the 1937 reissue in the Everyman series E. S. Pearson returned to the chapter plan of 1892 but kept the wording of 1900; he also wrote an introduction. In 1991 Thoemmes published a reprint of the first edition with an introduction by Andrew Pyle. For discussion see Porter (2004, ch. 3) and E. S. Pearson (1936, pp. 214-7) and (1938, pp. 185-6).
This contains both statistical and historical studies of evolution. The latter include reconstructions of prehistoric society based on the “fossils” of language and customs. Behind the long study of the “German Passion-Play” is the thought that the mediæval philosophy of life contained “social, economic, and æsthetic elements wanting in the civilisation of today.” For discussion see Porter (2004, ch. 3) and E. S. Pearson (1936, p. 225) .

This gives Pearson’s views on nations, socialism and eugenics: “We find that the law of survival of the fitter is true of mankind, but that the struggle is that of the gregarious animal. A community not knit together by strong social instincts by sympathy between man and man, and class and class cannot face the external contest…” In the second edition the original lecture was supplemented by data appendices
Karl Pearson (1914) Tables for Statisticians and Biometricians, Cambridge: Cambridge University Press.
The main purpose of these first tables was to assist in the fitting of the Pearson curves. More specialised volumes came later as well as a Part II in 1931. Much effort went into table-making and it was an activity Pearson rated highly: “What the true statistician, the true physicist demands” is “the conversion of algebraical results into tables;” an “all-round mathematician” needs to be a “computer.” (Lectures on the History of Statistics, p. 245.)

In old age Pearson wrote affectionately of his student days in the 1870s
In fact, his experience at the time, as described in Andrew Warwick’s Masters of Theory: Cambridge and the Rise of Mathematical Physics, Chicago UP (2003) and based on letters to his family, seems to have been rather unhappy.
Two anthologies of “fin de siècle” writing have snippets of Pearson: Ledger & Luckhurst have extracts from National Life and the Grammar of Science, Jay & Neve have extracts from National Life and the Scope and The Importance to the State of the Science of National Eugenics (1907).

Much of Pearson’s most important statistical work appeared in conjunction with biological ideas which are now obsolete—e.g. his fundamental work on correlation is in the 1896 paper on “Regression, Heredity and Panmixia”. However his first chi-squared paper, Pearson (1900), does not contain difficult biological matter. It appears with notes by G. A. Barnard in
S. Kotz & N. L. Johnson (ed.) (1992) Breakthroughs in Statistics Volume 1, New York, Springer-Verlag.
Pearson wrote no textbook but the chapters on evolution in the 2nd edition (1900) of the Grammar of Science make a good introduction to his way of doing statistics. A “statistical methods for research workers” could be compiled from the introductions he wrote for his books of tables, especially Tables for Statisticians and Biometricians. Elderton’s Pearsonian textbook covers fitting the Pearson curves and correlation:
Writing about Pearson
The following selection from the secondary literature is organised under four headings: philosophy, statistics, biology and society. Pearson’s work does not divide so neatly and several items could as well appear elsewhere; this polyvalence is probably one of the appeals of Pearson research. Here I mention some works spanning the categories.
The new biography by Porter has a different emphasis from most of the literature on Pearson for it focuses on the formation of the statistician
T. M. Porter (2004) Karl Pearson: the Scientific Life in a Statistical Age. Princeton NJ: Princeton University Press.
The book makes impressive use of the abundant archival material to give a very full account of Pearson’s life and thoughts in the period before 1900, treating his later career in more cursory fashion. The treatment of Pearson’s work in literature, history and physics and his first efforts in statistics is much fuller than that available elsewhere. The first part of E. S. Pearson’s biography had covered similar territory but in much less detail and with less discussion of the subject’s motivation. Porter’s book has been widely and favourably reviewed. See here for a list of the reviews. Two are available on-line: Lee in Notes and Records of the Royal Society, 59, (2005) pp. 92-3 and Aldrich in American Scientist.
The inter-connectedness of Pearson’s work was taken for granted by his contemporaries. More recently it has been emphasised by the sociologist MacKenzie and historian Magnello.
MacKenzie’s sociology of scientific knowledge approach has been criticised by Sullivan (see also Olby)
P. Sullivan (1998) An Engineer Dissects Two Case Studies: Hayes on Fluid Mechanics and MacKenzie on Statistics in N. Koertge (ed.) A Home Built on Sand: Exposing Postmodernist Myths about Science, New York: Oxford University Press.
D. A. MacKenzie (1999) The Science Wars and the Past’s Quiet Voices, (with response by P. Sullivan and reply by Mackenzie), Social Studies of Science, 29, 199-234.
The danger of over-simplifying Pearson’s activities is emphasised by
M. E. Magnello (1999) The Non-correlation of Biometrics and Eugenics: Rival Forms of Laboratory Work in Karl Pearson’s Career at University College London, (In two Parts), History of Science, 37, 79-106, 123-150.
Galton had an important influence on both Pearson’s statistical work and his genetical work. Two new biographies discuss Pearson and his relationship with Galton
N. W. Gillham (2001) A Life of Sir Francis Galton: From African Exploration to the Birth of Eugenics, New York: Oxford University Press.
M. Bulmer (2003) Francis Galton: Pioneer of Heredity and Biometry, Baltimore, Johns Hopkins University Press.
Pearson’s quarrel with R. A. Fisher encompassed both statistics and genetics. Fisher’s side is described by
J. F. Box (1978) R. A. Fisher: The Life of a Scientist, New York: Wiley.
The relationship between Pearson’s philosophy of science and his genetics is discussed by
B. Norton (1975) Metaphysics and Population Genetics: Karl Pearson and the Background to Fisher’s Multi-factorial Theory of Inheritance, Annals of Science, 32, 537-553.

The philosophies of Pearson and Weldon are distinguished by
C. H. Pence (2011) “Describing our whole experience”: The Statistical Philosophies of W. F. R. Weldon and Karl Pearson,
Studies in History and Philosophy of Biological and Biomedical Sciences, 42, (4), 475-485.
The relationship between Pearson’s philosophy of science and his thinking about correlation is discussed by Hilts and by
Pearson’s position on spurious correlation is treated in the Earliest Known Uses entries on “spurious correlation” and “Simpson’s paradox”.
The most thorough biographical account of Pearson’s work in physics and the philosophy of science is in chapter 3 of Porter (2004). Modern textbooks seldom mention Pearson’s contributions to applied mathematics/physics, though the Pearson-Todhunter History is still referred to. Nor is there much historical literature; there are a few remarks in
M. Jammer (1961) Concepts of Mass in Classical and Modern Physics, Cambridge MA: Harvard University Press.
L. A. Godoy (2006) Historical Sense in the Historians of the Theory of Elasticity, Meccanica, 41, Number 5, October, 2006.
Pearson’s philosophy of science has received more attention. Passmore and Porter discuss it in relation to the ideas of other late 19th century physicists. Skagestad focusses on Peirce and Piovani on the Vienna Circle.

Joachim Thiele (1969) Karl Pearson, Ernst Mach, John B. Stallo: Briefe aus den Jahren 1897 bis 1904, Isis, 60, 535-542. JSTOR
Porter draws on Pearson’s novel and passion play to discuss his philosophy taken more broadly—including his attitudes to religion and socialism—in
T. M. Porter (1999) Reason, Faith, and Alienation in the Victorian Fin-de-Siècle in H. E. Bodecker (ed.) Wissenschaft als Kulturelle Praxis. Gottingen: Vandenhoeck & Ruprecht.
In this essay Porter compares Pearson with John Henry Newman. Levine compares him with Walter Pater:
George Levine (2000) Two Ways Not To Be a Solipsist: Art and Science, Pater and Pearson, Victorian Studies, 43, 7-42.
George Levine (2008) Realism, Ethics and Secularism: Essays on Victorian Literature and Science, Cambridge University Press.
Herbert detects Feuerbach’s influence in the Grammar of Science
Christopher Herbert (1996) Science and Narcissism, Modernism/Modernity, 3, 129-135.
Christopher Herbert (2001) Victorian Relativity: Radical Thought and Scientific Discovery, University of Chicago Press.
The Grammar made little impression on professional philosophers but it was inspiring to a number of scientifically-minded youngsters including Harold Jeffreys and Jerzy Neyman. Raymond Pearl testified to this influence on his generation.
Pearson’s name appears in statistics textbooks in connection with chi-squared, correlation, goodness of fit, method of moments and the Pearson system of curves. However these books rarely contain much information about the man or about the context of his work.
There is a good account of Pearson’s earliest statistical work in chapters 8 and 9 of Porter (2004). Another useful account containing much biographical information is
M. Eileen Magnello (2005) Karl Pearson and the Origins of Modern Statistics: An Elastician becomes a Statistician, Rutherford Journal, 1 (1) here

Walker’s history looks back from the Pearsonian present of 1929. Hilts presents a rounded picture of “the first mathematical statistician in England”. Tankard’s introductory textbook has a chapter on Pearson plus ones on Galton, Gosset and Fisher. Porter has written a wide-ranging essay in the history of ideas. Hald and Stigler have written complementary volumes on ‘technical’ statistics: Hald emphasises the mathematical theory while Stigler is as concerned with the use of the theory. Apart from Hald the coverage tends to stop at 1900. By that date Pearson had done his most influential work but he still had hundreds of publications in front of him. Stigler’s 2012 article (written for the centenary of the University College Statistics Department) provides an overview of Pearson’s work. Aldrich places him with Galton and Fisher.
The International Statistical Review marked the Pearson sesquicentenary with a special issue. Appropriately enough, the articles emphasise Pearson’s international influence.

There is a large literature touching on Pearson in this area—and the following is only a selection. Pearson’s work has not only attracted attention from regular historians of science but from students of the sociology of scientific knowledge (see above) and the philosophy of science.
Pearson’s biology is put in various historical contexts by
P. J. Bowler (1989) The Mendelian Revolution: The Emergence of Hereditarian Concepts in Modern Science and Society, London: Athlone Press.
W. B. Provine (1971) The Origins of Theoretical Population Genetics, Chicago: University Press.

J. Gayon (1998) Darwinism’s Struggle for Survival: Heredity and the Hypothesis of Natural Selection, Cambridge: Cambridge University Press.
P. R. Sloan (2005/8) Evolution in the Stanford Encyclopedia of Philosophy.
Bowler is very brief. The other works have much more to say.

In statistics and biology there has long been a sense that Pearson’s work had been absorbed and that nothing new can be learnt from it. Yet occasionally one of his ideas is picked up and developed as e.g. the correlation curve
