A locus classicus in the historiography of (early) 19th century mathematics is that of the divide between French and English practices and conceptions of that science -- a divide often framed in terms of foundational approaches, and pedagogical practices, and cultural matrices. A closer look at this historiography, however, reveals that it draws on a rather narrow conception of its subject: be it by the limited sample of mathematical topics it engages with or by the few locales it visits -- to put it bluntly, calculus and its foundations in Paris and Cambridge exclusively. This paper proposes to reassess this narrative in light of a more expansive selection of episodes in the history of mathematics, and, in doing so, to question the relevance of such sweeping national and cultural categories.
The historiographical notion of a "supposed decline of 'British mathematics' after the death of Isaac Newton" has been "thoroughly nuanced, if not outright debunked", as Brigitte Stenhouse and Nicolas Michel write in the seminar prospectus. At present, we can read several historical accounts of the development of 18th-century calculus and algebra, and even accounts in which not only "pure" mathematics is considered, but in which "importance is given to other disciplines such as geometry, mechanics, or applied mathematics" (seminar prospectus). Indeed, we can refer to several histories of 18th-century calculus, algebra, the analytical mechanics of extended bodies, and celestial mechanics. However, notwithstanding the "debunking" of the "decline thesis", when we read the above accounts, even the recent fine chapters by June Barrow-Green, Jeremy Gray and Robin Wilson, and by Jeanne Peiffer (see the References), we are struck by the fact that very few British mathematicians active in the second half of the 18th century are mentioned, and those few only in passing. Note: this is not a criticism of the above chapters!!! Quite the contrary. I am referring to these chapters as examples of the best we can hope to read in this field. I simply love them, and I think there is much to be learned from studying them, as I will try to do in my talk. This talk is proposed as an attempt to discuss the “decline of 18th century British mathematics thesis” in the light of the best recent historiography of 18th-century mathematics (viz. the above chapters). I will also draw freely on two of my own papers (see the References) in order to reconsider them with a critical eye.

As a woman in late eighteenth- to early nineteenth-century Britain, Mary Somerville was almost unique in cultivating for herself a reputation as an expert mathematician. Much of this reputation relied upon recognition of her studies of mathematics recently developed in Paris, especially the work of Pierre-Simon Laplace in physical astronomy. Indeed in 1827, the President of the Society for the Diffusion of Useful Knowledge stated that if Somerville was not to translate Laplace’s Mécanique Céleste into English, then ‘none else can, and it must be left undone’. Restricted from other forms of legitimisation, such as the title of Wrangler for successful Cambridge students or the full membership of a learned society, Somerville deftly positioned herself as an expert in the science and mathematics that was seen by some as the answer to a perceived decline in British science. Rather than critiquing delineations between French and British mathematics, this talk will treat them as actors’ categories and investigate how they were used by Somerville to find community and respect as a mathematician.
This paper examines the circulation of descriptive geometry - a mathematical theory formalizing projection techniques for the flat drawing of three-dimensional objects - in carriage woodworkers and makers’ drawing practices at the end of the 19th century. The use of descriptive geometry in this professional milieu was first documented in France; the mathematical theory then circulated in England and the United States with a different fervor and intensity. English and American carriage makers were not unambiguous in their assessment of the relevance of the “French Rule”, a discrepancy that I will attempt to explain by examining the use of stereotomic representation of volumes on both sides of the Channel, as well as American carriage makers representations of so-called “English mathematics” and “French mathematics”.
