Hertha Sponer’s (1894-1968) early years in physics were spent at the center of the quantum revolution. Training as an experimentalist under Debye, then heading the spectroscopy labs in Göttingen uniquely situated her to contribute to the development of quantum theory and the emergence of quantum chemistry, by novel interpretations of hitherto unexplained spectrographic data using quantum mechanics, and suggesting new applications of the theory to atoms and diatomic molecules. Sponer’s name has nevertheless been largely written out of scientific accounts of these years. When mentioned in the context of quantum theory, it is usually as Franck’s “assistant” (incorrect) and second wife – descriptions that obscure her status as a world-renowned scientist who’d contributed importantly to physics and chemistry over a long and illustrious career. Extant accounts of Sponer’s life and work almost exclusively concern her postwar years as a professor at Duke. But by then quantum theory was well established, and her research had pivoted in other directions. This chapter aims to introduce Sponer into the history of early quantum theory, with appropriate attention to her achievements.

John Wheeler (1911−2008), besides being a key figure in twentieth-century physics in his own right, was also an exceptional mentor and a key witness to historical events. Little known is that his first PhD student was a woman, Katharine Way (1902−1995), who notably played an important role in the postwar organization and dissemination of nuclear data. In the 1990s, Wheeler further made the surprising claim that Way’s work while she was his student came very close to anticipating the discovery of nuclear fission. In addition to gathering the few pieces of information about Way’s early work, this chapter provides a contextualization and evaluation of Wheeler’s words by analyzing his peculiar communicative style, which often subtly mixed history, personal experience, and theoretical insights or guiding ideas. To illustrate this, Wheeler’s pages about personalities such as Marie Curie, Lise Meitner, Maria Goeppert Mayer, and Way herself are considered. It emerges how Wheeler’s original viewpoint has to be properly discussed when evaluating his claim about his former student’s work.

The epilogue summarises the main themes and approach of the book and looks ahead to possible futures for forms of religion similar to those practised by unchristianised peoples in the past in a post-Christian Europe.

This chapter connects the fiction of Joaquim Antonio Machado de Assis to the Brazilian dance and martial art of capoeira, initially through a sustained analysis of the Machado de Assis story “The Secret Cause,” then through a larger discussion of trickery and reinterpretation of structures of power in capoeira and in the fiction of Machado de Assis

This chapter sets out the debates that have grown up around CEOs, highlighting three major reasons why they warrant serious study: their importance to the companies they lead, their wider economic and political power, and what their careers tell us about social mobility. To address these debates the book explores three questions: Who were the CEOs and how did they get into the role? What did they do? Did they matter for their companies and Britain’s economy and society? To answer these questions, a unique database of the CEOs of the top 100 most valuable UK public companies between 1900 and 2009 has been assembled. This consists of 475 companies and 1,397 CEOs. For each CEO a career biography is created. To analyse the data, we draw on Upper Echelons Theory and Agency Theory, alongside historical scholarship to understand the environments in which they operated. The chapter then sets out the five analytical threads that are developed throughout the book. The chapter closes by discussing how the nomenclature around top corporate officers evolved from ‘chairman’ to ‘managing director’ to ‘chief executive officer’.

After World War II, Britain’s CEOs faced major economic challenges. International competition increased, and Harold Wilson called for a managerial revolution to exploit the white heat of new technology. This chapter examines whether this revolution occurred. Engineers, including Leonard Lord and George Harriman of the British Motor Corporation, and accountants, like John Davis of Rank and Leslie Lazell of Beechams, made up an increasing proportion of top CEOs. These trends increased social diversity with over 70 per cent of CEOs rising through merit rather than social position or family. Yet, British CEOs had significantly less formal education and specialist management training than their competitors. In 1950, 36 per cent of British CEOs had an undergraduate degree. The equivalent figures were 75, 75, and 95 per cent in the United States, Germany, and France. Although training in accountancy and engineering brought a focus on optimisation and efficiency, it lacked more holistic approaches to management, resulting in bureaucratic organisations and siloed thinking. The managerial revolution failed, innovation and productivity suffered, and economic malaise set in.

The Reformation and Counter-Reformation had a profound effect on the treatment of unchristianised peoples in Europe, intensifying efforts to convert them to Christianity, while Protestants and Catholics vied to establish their own version of the faith as the true one. The theme of paganism, intensely polemicised, occupied a central place in the religious rhetoric of the Reformation, with Protestants accusing Catholics of being little more than pagans while Catholics in turn denounced Protestants as infidels with no respect for the holy. The result was the effective reinvention of the concept of paganism, which came to be identified with folk religion (and, more specifically, folk Catholicism). ‘Paganism’ became both a greedy and a fuzzy concept, blurring the lines between those who were poorly catechised and those who were wholly unchristianised. Furthermore, ideas of infidels and idolaters formed in the New World were reimported to Europe in this period. This chapter seeks to dispel the fog of Reformation polemic in order to determine what we can know of unchristianised peoples in Europe during this period, when Orthodox Muscovy was also expanding eastward into unchristianised areas of Europe’s far east.

This chapter explores the assassination of crusading city councilwoman Marielle Franco in 2018, the mobilization of her supporters in the wake of that assassination, and the election of several Black women legislators in the ensuing years. The chapter traces Franco’s trajectory as the daughter of Black and Northeastern residents of the Maré favela complex, her path through growing educational opportunities in the early 2000s, her political emergence in connection with politician Marcelo Freixo and the PSOL party. It also explores the reactionary militias apparently responsible for her death, and their connection to police corruption and territorial violence, particularly on Rio’s west side.

Laura M. Chalk (later, Laura Rowles, 1904−1996) was the first woman to complete a PhD in physics at McGill University in Montreal, Canada. Her doctoral research on the quantum phenomenon called the Stark effect, under the supervision of J. Stuart Foster, produced the earliest experimental test of Erwin Schrödinger’s wave mechanics. After a brief stint as a postdoctoral fellow at King’s College London, she chose to return home and dedicate herself to teaching and marriage. This paper aims to fully recover Chalk’s work and explore why the Foster−Chalk experiment was overlooked in physics historiography. It considers the Stark effect’s significance in quantum physics and the impact of gender on her personal trajectory. Shaped by personal choice, systemic discrimination, and acceptance of societal norms, Chalk Rowles’ story highlights the paradoxes faced by women in a culturally disembodied yet male-dominated field, and reflects broader themes of gender and identity in the history of women in physics.
