Sir Edmund Taylor Whittaker (24 October 1873 – 24 March 1956) was a British mathematician, physicist, and historian of science. Whittaker was a leading mathematical scholar of the early 20th century who contributed widely to applied mathematics and was renowned for his research in mathematical physics and numerical analysis, including the theory of special functions, along with his contributions to astronomy, celestial mechanics, the history of physics, and digital signal processing.
Among the most influential publications in Whittaker's bibliography, he authored several popular reference works in mathematics, physics, and the history of science, including A Course of Modern Analysis (better known as Whittaker and Watson), Analytical Dynamics of Particles and Rigid Bodies, and A History of the Theories of Aether and Electricity. Whittaker is also remembered for his role in the relativity priority dispute, as he credited Henri Poincaré and Hendrik Lorentz with developing special relativity in the second volume of his History, a dispute which has lasted several decades, though scientific consensus has remained with Einstein.
Whittaker served as the Royal Astronomer of Ireland early in his career, a position he held from 1906 through 1912, before moving on to the chair of mathematics at the University of Edinburgh for the next three decades and, towards the end of his career, received the Copley Medal and was knighted. The School of Mathematics of the University of Edinburgh holds The Whittaker Colloquium, a yearly lecture, in his honour and the Edinburgh Mathematical Society promotes an outstanding young Scottish mathematician once every four years with the Sir Edmund Whittaker Memorial Prize, also given in his honour.
Life
Early life and education Edmund Taylor Whittaker was born in Southport, in Lancashire, the son of Selina Septima (née Taylor) and John Whittaker. He was described as an "extremely delicate child", necessitating his mother to home school him until he was 11 years old, when he was sent off to Manchester Grammar School. Ernest Barker, a classmate of Whittaker's at the Grammar School with whom he shared the office of prefect, later recalled his personality: "He had a gay, lively, bubbling spirit: he was ready for every prank: he survives in my memory as a natural actor; and I think he could also, on occasion, produce a merry poem."Ernest Barker (1953) Age and Youth, p 280, Oxford University Press While at the school, Whittaker studied on the "classical side", devoting three-fifths of his time to Latin and Greek. Whittaker struggled with the poetry and drama which was required by the upper school, and expressed gratitude for being allowed to leave these studies behind and specialise in mathematics.
In December 1891 Whittaker received an entrance scholarship to Trinity College, Cambridge. After completing his education at the Manchester Grammar School he went on to study mathematics and physics there from 1892 to 1895. He entered Trinity College as a minor scholar in October 1892 to study mathematics. Whittaker was the pupil of Andrew Russell Forsyth and George Howard Darwin while at Trinity College and received tutoring throughout his first two years. With an interest more in applied than pure mathematics, Whittaker won the Sheepshanks Astronomical Exhibition in 1894 as an undergraduate. He graduated as Second Wrangler in the Cambridge Tripos examination in 1895. The Senior Wrangler that year was Thomas John I'Anson Bromwich and Whittaker tied John Hilton Grace for second, all three along with three other participants, including Bertram Hopkinson, went on to be elected Fellows of the Royal Society. He also received the Tyson Medal for Mathematics and Astronomy in 1896.
Career Whittaker was a fellow of Trinity College, Cambridge from 1896 to 1906 when he was appointed Andrews Professor of Astronomy at Trinity College Dublin and Royal Astronomer of Ireland. He held these posts until 1912, when he was appointed chair of mathematics at the University of Edinburgh, a role he went on to hold for just over a third of a century. Throughout his career, he wrote papers on automorphic functions and special functions in pure mathematics as well as on electromagnetism, general relativity, numerical analysis and astronomy in applied mathematics and physics, and was also interested in topics in biography, history, philosophy and theology. He also made several important innovations in Edinburgh that had a large impact on mathematical education and societies there.
Trinity College, Cambridge In 1896, Whittaker was elected as a Fellow of Trinity College, Cambridge, and remained at Cambridge as a teacher until 1906. In 1897, Whittaker was awarded the Smith Prize for his work on the paper "On the connexion of algebraic functions with automorphic functions", published in 1888.
In 1902, Whittaker found a general solution to Laplace's equation, which received popular news coverage as a "remarkable discovery", though the mathematician Horace Lamb noted that it did not offer any new features. He also wrote several celebrated books in his early career, publishing A Course of Modern Analysis in 1902 and following it up with A Treatise on the Analytical Dynamics of Particles and Rigid Bodies just two years later in 1904. In September of that year, Whittaker was forced to sell six silver forks at an auction to pay back taxes which he had previously refused to pay due to the Education Act 1902 requiring citizens to pay taxes to fund local Christian schools, such as the Roman Catholic Church and the Church of England.
Prior to being compelled by a magistrate to repay the tax burden, Whittaker was one of several activists who engaged in passive resistance by refusing to pay the taxes. In 1905, Whittaker was elected as a fellow of the Royal Society in recognition of his achievements.
Trinity College Dublin In 1906, Whittaker was appointed Andrews Professor of Astronomy at Trinity College Dublin, which came with the title Royal Astronomer of Ireland. He succeeded Charles Jasper Joly at the post and was appointed upon recommendation from the astronomer Robert Stawell Ball.
Ball's recommendation, which was published in a collection of his letters in 1915, stated that Whittaker was the only person he knew who could "properly succeed Joly" and that the role would "suit him in every way". He then describes Whittaker as "modest" and "charming" and as "a man who has infinite capacity for making things go". Ball said Whittaker was a world-leading expert in theoretical astronomy and that, in relation to Whittaker's discovery of a general solution to Laplace's equation, notes that he "has already made one discovery which the greatest mathematician of the last two centuries would be proud to have placed to his credit".
The Royal Astronomers acted as directors for the Dunsink Observatory, which used outdated astronomy equipment; it was understood that the primary responsibility of the role was to teach mathematical physics at Trinity College. During this time, the relative leisure of his post allowed him to complete the reading required to write his third major book A History of the Theories of Aether and Electricity, from the age of Descartes to the close of the nineteenth century. Also during this time, he wrote the book The Theory of Optical Instruments, published six astronomy papers, and published collected astronomical observations.
University of Edinburgh
Whittaker became Professor of Mathematics at the University of Edinburgh in January 1912, where he remained for the rest of his career. The role was left vacant by the death of his predecessor, George Chrystal in 1911. He was elected as a Fellow of the Royal Society of Edinburgh in 1912, after being nominated by Cargill Gilston Knott, Ralph Allan Sampson, James Gordon MacGregor and Sir William Turner. He served as Secretary to the Society from 1916 to 1922, the Vice President from 1925 to 1928 and from 1937 to 1939, and was President of the Society from 1939 to 1944, through the war years. Whittaker began holding "research lectures" in mathematics at the university, typically given twice a week. He was said to be a great lecturer by one of his previous attendees, who stated that his "clear diction, his felicity of language and his enthusiasm could not fail to evoke a response" and that he was very good with illustrations.
Freeman Dyson commented on Whittaker's lecture style by saying that students were "warmed, not only by the physical presence of a big crowd packed together, but by the mental vigour and enthusiasm of the old man". Whittaker's efforts helped transform the Edinburgh Mathematical Society from a teachers society to an academic research society and was a major driving force in introducing computational mathematics education to the UK and America.
Shortly after coming to Edinburgh, Whittaker established the Edinburgh Mathematical Laboratory, one of the UK's first mathematical laboratories. The laboratory was the first attempt of a systematic treatment of numerical analysis in Great Britain and friends of Whittaker have said he believes it to be his most notable contribution to the education of mathematics. Subjects taught at the laboratory included interpolation, the method of least squares, systems of linear equations, determinants, roots of transcendental equations, practical Fourier analysis, definite integrals, and numerical solution of differential equations. The laboratory program was so successful, it resulted in many requests for an extra summer course to allow others to attend who previously were unable, ultimately leading to the establishment of a colloquium through the Edinburgh Mathematical Society. In 1913, Whittaker established the Edinburgh Mathematical Society Colloquium and the first was held over five days in August of that year.
The textbook The calculus of observations was compiled from courses given at the Laboratory over a ten-year period; the book was well received and ultimately went through four editions.
Fellowships and academic positions Outside of the Royal Astronomer of Ireland and his roles in the Royal Society of Edinburgh, Whittaker held several notable academic posts, including president of the Mathematical Association from 1920 through 1921, president of the Mathematical and Physical Section (Section A) of the British Science Association in 1927, and was president of the London Mathematical Society from 1928 through 1929. Whittaker also held the Gunning Victoria Jubilee Prize Lectureship for "his service to mathematics" with the Royal Society of Edinburgh from 1924 through 1928.
He was elected either Honorary Fellow or Foreign Member in a number of academic organisations, including the in 1922, the Societa Reale di Napoli in 1936, the American Philosophical Society in 1944, the Académie royale de Belgique in 1946, the Faculty of Actuaries in 1918, the Benares Mathematical Society in 1920, the Indian Mathematical Society in 1924, and the Mathematical Association in 1935. In 1956, he was elected as a corresponding member of the Geometry section of the French Academy of Sciences a few days before his death. Whittaker was also awarded honorary doctorates from several universities, including two LLDs from the University of St Andrews in 1926 and the University of California in 1934, an ScD from the Trinity College Dublin in 1906, and two D.Sc.s from the National University of Ireland in 1939 and University of Manchester in 1944.
Later life Whittaker published many works on philosophy and theism in the last years of his career and during his retirement in addition to his work on the second edition of A History of the Theories of Aether and Electricity. He released two books on Christianity and published several books and papers on the philosophy of Arthur Eddington.
