This article concentrates on the period between 1818 and 1858, from Playfair’s birth to his appointment as Professor of Chemistry at the University of Edinburgh. His biographer (Sir Thomas Wemyss Reid) described his life as a ‘story not of adventure, but work’ and yet his record was one of energetic enterprise that had considerable impact. He was a rising star in the then fashionable world of chemistry, a favoured student of the founder of organic chemistry, Justus Liebig, and a central figure in the promotion of new ideas in agricultural science.[1] A career in science and the state saw him connected to the leading figures of both, and he played a crucial role in the conceptual and financial success of the Great Exhibition, and its legacy. His brilliance has been overshadowed by the extrovert Henry Cole, and yet Playfair was essential to the major educational reforms of their time. N1 - Justus Liebig did not become a baron until 1845 and so is not referred to in this article as Justus von Liebig. N1 - This article was developed from a lecture (‘Lyon Playfair: Chemist and Commissioner’) given by the author at the Chemistry in Albertopolis conference on 11 April 2019. The conference formed part of a series of events organised by the Science Museum’s Research and Public History Department. These were part of wider celebrations by the cultural organisations of ‘Albertopolis’ to mark the bicentenary of the birthdays of Prince Albert and Queen Victoria, and the International Year of the Periodic Table, invented by Dmitri Mendeleev 150 years earlier. The series of events aimed to explore how chemistry took root, flowered and continues to flourish in the cultural and scientific quarter of South Kensington. Key partners were the Science Museum, Imperial College, the Victoria and Albert Museum, The Commission for the Exhibition of 1851, the Royal College of Music, the Royal Albert Hall and the Natural History Museum. N1 - The major biography of Henry Cole (The Great Exhibitor: The Life and Work of Henry Cole) was published in 2003 by Elizabeth Bonython and Anthony Burton. Inevitably, Cole also features very prominently in Burton’s landmark history of the Victoria and Albert Museum (Vision and Accident: The Story of the V&A). N1 - Armstrong wrote in 1976 of the need for a new biography too. N1 - Professor Thomas Duncan, Chair of Mathematics (1820–1858) N1 - Frustratingly, Playfair only refers to his fellow clerk by surname. I am grateful to my research assistant, Katie Dowler, for tracking down the details of Andrew Ramsay’s two brothers: William (born 1811) and John (born 1816), who would have been 24 and 19 respectively at the time Playfair was clerking in Glasgow; and so John seems the likely candidate as the most similar in age to Playfair (17).

N1 - In this context dialysis refers to the method by which large molecules and small molecules can be separated. The principle was used in the development, very much later than Graham, of kidney dialysis in the mid twentieth century. Playfair cites Graham’s work on water crystallisation, the diffusion of gases and the modification of phosphoric acid as being ‘classical examples of investigation’. In 1831, Graham had given a paper to the Royal Society of Edinburgh in which he showed that, at constant pressure, the rate of diffusion of gas was inversely proportional to the square root of its density – a principle that has become known as ‘Graham’s Law’. A fuller account can be in found in his Dictionary of National Biography entry (Michael Stanley). N1 - Playfair gives no detailed explanation for his affliction and so I am grateful to Dr Roger Highfield (Science Director, Science Museum) and Natasha McEnroe (Keeper of Medicine) for some interpretation. It is possible that Playfair may have been using methylated spirit (rather than formalin, which came in to use from the 1890s), which has evidenced links to dermatitis. However, in the 1830s it was not yet common practice to preserve cadavers, although a chlorate of lime was used to wash the bodies and reduce smell. It was used at this time more generally as an anti-putrefaction agent and could cause skin irritation. We might also speculate on eczema’s links to emotional well-being because hospitals and dissecting rooms could be highly stressful places at this time. N1 - From the sparse details Playfair provides one can ascertain that this circle included Sir John McClelland (geologist), Nathaniel Wallich (botanist) and the leading oriental antiquarian James Prinsep. Playfair does not tell us anything about the origins of such encounters although one could speculate that the offices of the Asiatic Society might well have played a central role. N1 - Liebig to Playfair, 6 November 1841 N1 - Augustus Granville (1783–1872), see entry in Dictionary of National Biography (Omella Moscucci). N1 - I am most grateful for my colleague Robert Bud for alerting me to these important omissions in Playfair’s account of this period. N1 - The comment is from Reid.
