James Jurin
Additional recommended knowledge
Early lifeJurin's father was John Jurin, a London dyer. His mother was John's wife Dorcas Cotesworth. He was educated at Christ's Hospital where he won a scholarship to Trinity College, Cambridge, graduating BA in 1705, and being elected fellow the following year. Becoming the protegé of the master of Trinity, Richard Bentley, Jurin became tutor to Mordecai Cary, travelling with him internationally. Jurin achieved his MA in 1709 and became headteacher of the Royal Grammar School, Newcastle. Jurin became a frequent public speaker on mathematics and the work of Sir Isaac Newton.[1] Jurin returned to Cambridge in 1715 to study medicine, becoming MD the following year and establishing a successful practice in London and Tunbridge Wells. In 1722, he lectured on anatomy to the Company of Surgeons.[1] From 1725 to 1732 he worked as a physician at Guy's Hospital, thereafter becoming a governor of the hospital. In 1724, Jurin married Mary Douglas, née Harris (died 1784), a wealthy widow, and they had five daughters and one son.[1] Medical practiceJurin rose to a position of some eminence in medicine and science. He is described as "witty, satirical, ambitious, and professionally and financially successful".[1] He was a powerful advocate of the smallpox vaccine, using an early statistical study to compare the risks of vaccination with those from contracting the disease naturally. He studied mortality statistics for London for the fourteen years prior to 1723 and concluded that one fourteenth of the population had died from smallpox, up to 40 percent during epidemics.[2] He advertised in the Proceedings of the Royal Society for readers to report their personal and professional experiences and received over sixty replies, most from other physicians or surgeons[1] but most significantly from Thomas Nettleton who reported his own calculations from his experience in several communities in Yorkshire.[2] Jurin's analysis concluded that the probability of death from vaccination was roughly 1 in 50, while the probability of death from naturally contracted smallpox was 1 in 7 or 8. He published his results in a series of annual pamphlets, An Account of the Success of Inoculating the Small-Pox (1723-1727). His work was very influential in establishing smallpox vaccination in England.[1] Jurin claimed that he had given "plain Proof from Experience and Matters of Fact that the Small Pox procured by inoculation ... is far less Dangerous than the same Distemper has been for many Years in the Natural Way."[2] Newtonian scientistJurin was an "ardent Newtonian". He had studied under Roger Cotes and William Whiston at Cambridge but only came to know Newton at the Royal Society, where Jurin was Secretary towards the end of Newton's Presidency. Always advocating the Newtonian position, he was a keen controversialist, corresponding with Voltaire, Georges-Louis Leclerc, Comte de Buffon and Émilie du Châtelet. He took an active part in defending Newton and attacking Gottfried Leibniz in the debate over vis viva,[1] opposing the views of Benjamin Robins and Pietro Antonio Michelotti.[3] Jurin fostered international observational research into weather and meteorology[1] and studied the phenomenon of capillary action, deriving the rule that the height of liquid in a capillary tube is inversely proportional to the diameter of the tube at the surface of the liquid only, a law sometimes known as Jurin's law.[4][5] He published on hydrodynamics and was critical of Jean and Daniel Bernoulli's work.[1] Jurin worked on iatrophysics, investigating the mechanical behaviour of the heart and the specific gravity of blood, debating the heart with John Keill and Jean-Baptiste de Sénac. He wrote an addendum (1738) On Distinct and Indistinct Vision to Robert Smith's Opticks and engaged in a lively epistollary exchange with Robins on the topic.[1] Controversy with BerkeleyIn 1734, George Berkeley published The Analyst in which he attacked the calculus as flawed and ultimately absurd. Between 1734 and 1742, Jurin published over three hundred pages in robust rebuttal of Berkeley, many of them employing his favourite weapon of satire. The publications, some under the pseudonym Philalethes Cantabrigensis, included Geometry no Friend to Infidelity, or A Defence of Sir Isaac Newton & the British Mathematicians (1734)[6] and The Minute Mathematician, or The Freethinker no Just Thinker (1735)[7]. Berkely quickly withdrew from the debate and Jurin turned his attentions on Robins and Henry Pemberton.[1] Later lifeJurin attended Robert Walpole as his physician and prescribed lixivium lithontripticum for Walpole's bladder stones. Jurin had used a similar prescription for himself but Walpole died and Jurin was blamed for his death, again necessitating an energetic pamphlet campaign to defend his practice.[1] Juring died in London and was buried at St James Garlickhythe. His estate was valued at £35,000 (£4.9 million at 2003 prices[8]) .[1] Offices and honours
