Eleanor Sidgwick’s hidden figures

During the 1890s Eleanor Sidgwick (always known as ‘Nora’ as by her friends) loved taking part in the regular Cambridge Ladies’ Dining Society discussions. ‘I have never anywhere else seen her more alive & interested,’ her friend and fellow-member Louise Creighton recalled. ‘She used to quite flush with excitement.’ (Creighton, 97) It’s a delightful image that seems to contradict the serious face of the woman in the portrait that hangs in Newnham College, Cambridge today (see above). She was the college’s first Vice-Principal and its second Principal at the end of the Victorian era, and taught mathematics to its students. ‘We had immense respect for her,’ one of them later recalled, ‘she was soft-voiced, slight in figure and generally pale in colouring, but in her grey eyes shone the light of the pure intellectual, quite unconscious of itself, but making one painfully aware of one’s own amateurish inferiority.’ (Phillips, 54)

Although she was known for her ‘fastidious austerity’ (Fowler, 7), Nora’s students knew that she could take a joke. One college production in 1895 featured a lively song with the lines: ”Mrs Sidgwick she up an’ sez ‘Look at the fax/…the one thing we ax/Is – do treat a girl as a rational creature.” (Fowler, 20) Her marriage to Newnham’s co-founder Henry Sidgwick was both an affectionate and a deeply rational partnership, based on working together to promote equal higher education opportunities for women. (They also shared a lifelong passion for psychical research, and probably met during a séance at her brother Arthur Balfour’s house: see Jane Dismore’s excellent guest post from 2017 here.) Eleanor Sidgwick’s ODNB entry notes that ‘her concern for women to be regarded as rational creatures naturally led her to support the growing campaign for women’s suffrage.’

Growing up in the Balfours’ stately home in East Lothian, Nora had always been treated as a rational creature herself. She showed an early aptitude for mathematics, so her mother Lady Blanche insisted that she should be taught Euclid alongside her brothers Arthur, Gerald and Frank. While they all went off to study at Eton and Cambridge, Nora stayed at home to manage the three large family estates, giving her a practical education in finance that would come in useful later. At Newnham she personally micro-managed the college accounts (‘chasing twopences’) and also had the far-sighted strategy to ensure the future of its campus site by purchasing adjoining land and organizing a new road, Sidgwick Avenue, planted with plane trees that she paid for herself.


A new book by Susannah Gibson, The Spirit of Inquiry: how one extraordinary society shaped modern science (OUP, 2019) shines light on another, less well known aspect of Nora’s work in Cambridge: as a physicist who contributed to Rayleigh’s discoveries. The Philosophical Society, the subject of Gibson’s excellent book, was a scientific society for Cambridge graduates which has had a worldwide influence since 1819, but for over a hundred years it did not accept women as members because they were not permitted to hold Cambridge degrees. In my recent Times Literary Supplement review, I wrote that my favourite chapter in the The Spirit of Inquiry is ‘A Workbench of One’s Own’ about the scientific work that Cambridge women were doing in their segregated, poorly equipped laboratories. Earlier in the book Gibson explores the work of Lord Rayleigh, who in 1904 became Cambridge University’s first Nobel Prize winner for his study of the density of gases and the discovery of Argon (see Katrina Dean’s ‘Discovery’ blogpost here). In the 1870s and 1880s Rayleigh worked alongside Cambridge graduates, but his ‘closest collaborator’, according to Gibson, was his sister-in-law Eleanor Sidgwick, ‘a brilliant experimenter ‘who co-published several papers with him and

‘worked painstakingly with Rayleigh and the others to set up the great spinning coils of wire, the scales and magnetometers, the Argand lamps, the looking glasses, and the telescopic eyepieces needed to record their measurements. The researchers often worked overnight, toiling away when the laboratory was silent and still, exhausting themselves in pursuit of the elusive numbers.’ (Gibson, 166)

This fascinating historical scientific work was recently highlighted in the ‘Discovery‘ exhibition at Cambridge University Library (see blog here). There are photographs of Rayleigh’s hand-crafted bird whistles and other apparatus that he devised to detect ultrasonic waves, including a box full of bright green iridescent beetles and even a delicate blue butterfly wing used in his experiments on light waves. The exhibition featured Newton’s own annotated copy of the Principia, a letter that Darwin wrote from the Beagle and an early typescript of Stephen Hawking’s A Brief History of Time (intriguingly with a different title). Also on display, for the first time ever, was the 1967 pulsar chart reading made by Jocelyn Bell Burnell, who as a PhD student rolled out her experimental charts on the long floor of the old Cavendish Laboratory. Seven years later it was her supervisor Anthony Hewish – not her – who was awarded the Nobel Prize, but despite this, Bell Burnell’s continuing work and influence have made her a role model for female scientists throughout the world. In 2018 she donated her $3 million Breakthrough Prize to the Institute of Physics to fund PhD studentships for people underrepresented in physics.

It’s not hard to imagine Nora Sidgwick’s serious face lighting up at this news. How interested she would be to see, and hear about, the scientific discoveries that male and female Cambridge scientists have made – and continue to make – by working together. Eleanor Sidgwick’s own ‘hidden figures’, like those of other women scientists, are part of that story.
