The extraordinary career of the British Quaker polymath, Silvanus Phillips Thompson (1851–1916), encompassed fame in physics, electrical engineering, mathematics, history of science, educational method, painting, music, textbooks, X-rays, popular lectures, the promotion of women's rights, book-collecting, and not least his leadership in encouraging fellow Quakers to embrace the challenging results of research in the natural sciences. His public-facing career, with a reputation that ranged across Western Europe at least, centred on the sincere yet critical communication of new technical and historical (...) knowledge, in a mastery of four languages. Yet his kaleidoscopic work has not received any sustained historical examination since the Life and Letters produced by his widow Jane and daughter Helen in 1920. The centenary of his death was marked by an interdisciplinary workshop at the Westminster (Quaker) Meeting-House, “‘A Many-sided Crystal’: The Quaker Physicist and Electrical Engineer Silvanus Phillips Thompson” on September 16, 2016. This spotlight section of Centaurus captures four of the revised contributions to that event, and these cover Thompson's contributions to historical theory, biographical practice, and commercial technology, as just a few elements of the rich and complex legacy that emerged posthumously from his multifarious, polymathic talents. These collectively point us to a revised view of Thompson as a pre-First World War European figure who gained his authority not from specialization in a single area of esoteric research, but from a life of public service that integrated the literary arts and historical writing with sciences and engineering, all incorporated within an active Quaker practice. The papers in this collection thus show how Thompson came to be an historian of science with an unprecedented mastery of contemporaneous techno-scientific arts and sophisticated skills in historical-biographical writing, working harmoniously in a secular world with a rigorous yet non-dogmatic faith.

This essay argues for the historicity of applied science as a contested category within laissez-faire Victorian British science. This distinctively pre-twentieth-century notion of applied science as a self-sustaining, autonomous enterprise was thrown into relief from the 1880s by a campaign on the part of T. H. Huxley and his followers to promote instead the primacy of “pure” science. Their attempt to relegate applied science to secondary status involved radically reconfiguring it as the mere application of pre-existing pure science. This new (...) notion of extrinsically funded pure science that would produce only contingently future social benefits as a mere by-product came under pressure during World War I, when military priorities focused attention once again on science for immediate utility. This threatened the Cambridge-based promoters of self-referential pure science who collectively published Science and the Nation in 1917. Yet most contributors to this work discussed forms of “applied” science that had no prior “pure” form. Even the U.K.'s leading government scientist, Lord Moulton, dismissed the book's provocative distinction between pure and applied science as unhelpfully “vague and artificial.”. (shrink)

This paper investigates the magnet as a classic “boundary object” of modern technoscientific culture. Equally at home in the nursery, dynamo, measuring instrument and navigational compass, its capricious performance nevertheless persistently eluded the powers of nineteenth century electromagnetic expertise in pursuit of the completely “permanent” magnet. Instead the untamed magnet’s resilient secularity required its makers to draw upon ancient techniques of chemical manipulation, heat treatment and maturation to render it eventually sufficiently stable in behaviour for orderly use in modern engineering. (...) The precise methods for accomplishing this quasi-permanence were typically protected by trade secrecy – until that is Marie Sklodowska Curie’s first research publication opened up this topic for rigorous comparative research in 1898. Nevertheless, over the next quarter century her work in this field was gradually eclipsed by heavily gendered citation practices, just as the futility of attempting to accomplish complete permanency in magnets was eventually established by Sydney Evershed in the 1920s.

Silvanus Phillips Thompson, FRS began his career in the 1870s when there were still few academic posts for scientists, and when it was still uncertain whether the newer professional ideals would overtake the older, more gentlemanly, ones – in terms of both career advancement and of what being a ‘good’ scientist entailed. Thompson's many scientific, technical and literary activities are discussed in this paper, as is his Quakerism, perhaps the chief motivating force in his life. The paper raises the question (...) of how success in science is measured, and shows how Thompson's sabbatarian impulse influenced both his scientific practice and his pedagogical approach. In detailing the ways in which Thompson made a successful career, despite his lack of professional research focus, the paper relates to larger contexts of science, class, religion and education in late nineteenth-century Britain.
