Individuals such as Giovanni Plana, Professor of Astronomy at the University in Turin, offered her access to their personal libraries, but this was nonetheless a sharp contrast to the lively, sociable scientific community she had been a part of in London. During this lengthy sojourn, Somerville published multiple highly successful books-giving surveys of recent scientific developments in the physical sciences and physical geography-yet she still felt on the outside of the scientific community. Moving to Italy had been decided upon for health reasons, to seek a better climate than the UK offered, and also in hope of living at a lower cost than in London. Reproduced with the kind permission of the Principal and Fellows of Somerville College, Oxford.īy 1870, when this tale begins, Somerville had been living a peripatetic life on the Italian peninsula for around thirty years. Self-Portrait of Mary Somerville, undated. I needed to know more about how and why Somerville returned to serious mathematical study when she was nearly ninety.įigure 1. I was immediately hooked, and could clearly picture Somerville at her writing table, expressing her gratitude that her “intellect still unimpaired”, before turning to mathematics, a subject that she had enjoyed for nearly eighty years. One page in particular took my breath away: a draft page from her autobiography, again featuring algebraic formulas down the side, in which she acknowledged that the end of her life was approaching but noted that she was perfectly content in the care and company of her beloved daughters.

Much to my surprise, this notebook was accompanied by 70 loose sheets in the shaky handwriting typical of Somerville much later in her life and full of algebraic calculations. I especially wanted to resolve the footnotes in my thesis that said, “I know relevant material exists, I just haven’t been able to look at it yet!” According to the online catalogue, one folder held a “notebook containing notes and comments in Mary’s hand on The Mechanism of the Heavens, n.d. In early 2022, I was delighted to again have access to the Somerville papers at the Bodleian Library, which I had been unable to consult for the final 18 months of my PhD owing to the Covid-19 pandemic. Mary Somerville’s mathematical works were the focus of my doctoral thesis, which sought to understand what it meant for Somerville, as a woman in 19th-century Europe, to be a mathematician. The work for which she is most famous is undoubtedly her 1831 Mechanism of the Heavens, a translation of Laplace’s formative Traité de Mécanique Céleste, in which he gave an analytical, algebraic treatment of physical astronomy.

Somerville’s earliest publications were solutions to puzzles printed in The New Series of the Mathematical Repository, through which she was one of the earliest adopters of the differential notation in Britain. This mathematics was widely believed to be the answer to a long-running decline in British science, owing to the fruitful applications of methods from the differential calculus and the calculus of variations. Somerville built her reputation in the drawing rooms of Edinburgh, London, and Paris, in which she demonstrated her expert knowledge of the analytical mathematics recently developed in France.
