Biography

Professional biography

I am Emeritus Professor of History of Mathematics in the School of Mathematics and Statistics having joined the OU as a full-time PhD student in 1989.  I worked in an art gallery in London for several years before studying mathematics as an undergraduate at Kings College London.  I then worked in the City for two years before returning to Kings to study for an MSc in mathematical physics, after which I went to the OU. I chose the OU for my PhD study because, at the time, it was the only university in the country which offered the opportunity for graduate study in history of mathematics in a mathematics department. 

I am the Archive Curator for the IMU, and a Visiting Professor at the LSE. I am a past chair of the International Commission on the History of Mathematics, and past President of the British Society for the History of Mathematics (BSHM). I was an elected member of the Council of the London Mathematical Society (LMS) and served as the Society's Librarian (2007-2018).  I was a speaker at the 2022 ICM.

In 2025 I was awarded the LMS/BSHM Hirst Prize for my research and leadership in history of mathematics.  In 2021 I was awarded the Royal Society Wilkins-Bernal-Medawar Medal for my research in 19th and 20th century mathematics, notably on the historical roots of modern computing, dynamical systems and the three-body problem.  The citation also referred to the special emphasis my work places on the under-representation of women in historical narratives and in contemporary mathematics and to my recent work on decolonising the mathematical curriculum.

Research interests

My research focuses on the history of 19th-20th century mathematics, particularly in Britain.  Recent studies concern the role of Cambridge mathematicians during WW1, and the use of geometric surface models in research and in teaching.  Current projects include studies on the contribution of George Birkhoff to topological dynamics, and the contribution of Hilda Hudson (1881-1965) to the development of mathematical epidemiology.

I have a special interest in the history of the gender gap in mathematics, and am working on the representation of women in mathematics as portrayed through a variety of media.  See, for example, my article on Philippa Fawcett, the woman who scored more highly than all the men in the Cambridge Mathematical Tripos of 1890, which was published in the LMS Newsletter (May 2020).

I was a member of the panel on The Gender Gap in Mathematical and Natural Sciences from a Historical Perspective at the 2018 ICM in Rio de Janeiro, after which I was interviewed by Plus Magazine. You can view the interview here.   I have also been interviewed by Womanthology and Pie News

Teaching interests

I am a co-author, together with Jeremy Gray and Robin Wilson, of The History of Mathematics a Source-Based Approach, which developed out of the pioneering OU course MA290 Topics in the History of Mathematics.  The first volume was published in 2019 and the second volume in 2022.

 

 

Impact and engagement

I have given talks to a variety of audiences, national and international, from schools to the University of the Third Age, including the Women of the World Festival, the Northern Ireland Science Festival, Gresham College, the Royal Society Summer Science Exhibition, and the Institute of Physics.  A selection are listed below. You can view my inaugural lecture “He denies the very existence of a woman mathematician” here

I was a member of the Advisory Panel for the new mathematics gallery in the London Science Museum (Mathematics: The Winton Gallery), which opened in 2016.  I also helped to curate the Sublime Symmetry exhibition at the Guildhall Art Gallery in 2018.

I have been the academic consultant and/or contributor to television programmes such as Magic Numbers: Hannah Fry’s mysterious world of mathematics (BBC4); Calculating Ada. The Countess of Computing (BBC4); The Story of Maths (BBC4); Attack of the Zeppelins (Channel 4); High Anxieties: the Mathematics of Chaos (BBC4); and radio programmes such as A Mathematician’s Guide to Beauty (BBC R4) and In Our Time (BBC R4).

Projects

Booth Legacy - History of Mathematics

A former student in history of mathematics, Mrs Booth, has left The Open University a legacy of c.£50,000 to be spent on ‘research in history of mathematics’. I believe an appropriate use of the funds would be to employ Tony Royle, who has recently completed his PhD under my supervision, as a part-time (50%) post-doctoral researcher for two years. Tony’s thesis, which relied on a number of previously unexplored archives and which built on earlier work of mine, was a study of mathematicians working on early British aeronautics during the First World War. One chapter of his thesis is a case study of three women mathematicians who contributed to the war effort through their work in aeronautics. He would like to expand this part of his thesis into a comprehensive study of women mathematicians working in aeronautics during the War. Tony’s PhD work has been extremely well-received—he has received many invitations to speak on it, both in the UK and abroad, and it was reported on in The Times (21 August 2017). As a former pilot and with the research he has already undertaken, Tony is uniquely qualified to undertake this important project. Furthermore, it would fit in extremely well with my own work on the history of the gender gap in mathematics—I was invited to speak on the topic at the 2018 International Congress of Mathematics in Rio de Janeiro—and that of another of my PhD students, Brigitte Stenhouse, who is working on the mathematics of the 19th century mathematician and scientist, Mary Somerville. Tony absolutely embodies the spirit of the OU—he also has OU undergraduate and master’s degrees, and was the 2018 recipient of the AOUG Baroness Lee of Ashridge Award—and it would be entirely fitting if the legacy were to enable him to take the next step in his academic career.
