The late 1960s witnessed a key conjunction between political activism and the history of science. Science, whether seen as a touchstone of rationality or of oppression, was fundamental to all sides in the era of the Vietnam War. This essay examines the historian Robert Maxwell Young's turn to Marxism and radical politics during this period, especially his widely cited account of the ‘common context’ of nineteenth-century biological and social theorizing, which demonstrated the centrality of Thomas Robert Malthus's writings on population for Charles Darwin's formulation of the theory of evolution by natural selection. From Young's perspective, this history was bound up with pressing contemporary issues: ideologies of class and race in neo-Darwinian evolutionary theory, the revival of Malthusian population control, and the role of science in military conflict. The aim was to provide a basis for political action – the ‘head revolution’ that would accompany radical social change. The radical force of Young's argument was blunted in subsequent decades by disciplinary developments within history of science, including the emergence of specialist Darwin studies, a focus on practice and the changing political associations of the history of ideas. Young's engaged standpoint, however, has remained influential even as historians moved from understanding science as ideology to science as work.

Imagine a scene sometime in the 1750s in the depths of west Wales. This was wild country. Even a century later, George Borrow called it a ‘mountainous wilderness … a waste of russet-coloured hills, with here and there a black craggy summit’. Through this desolation rides the Reverend William Williams. As he rode, he read – and the book in his saddlebags on this occasion was William Derham's Astro-Theology, first published some twenty years earlier. Williams was a leading figure in the Methodist revolution that had been sweeping through Wales for the past two decades. Disenchanted with an Anglican Church that seemed increasingly disconnected – culturally and linguistically – from their everyday lives, and attracted by powerful and charismatic preachers like Williams himself, men and women across Wales turned to Methodism. They organized themselves into local groups worshipping in meeting houses rather than in their parish churches. Leaders like Williams usually had a number of such groups under their care, and spent much of their time on horseback, travelling between widely scattered communities to minister to their congregations. That Williams read in the saddle is well known. As shall become clear, he had certainly read Derham's book as well. It is not too much of an imaginative leap, therefore, to picture him reading about God's design of the cosmos as he rode through the Welsh hills – and it is a good image with which to begin a discussion about Wales, science and European peripheries.

This article, which focuses on the political decision making around the leadership of India's Atomic Energy Commission (AEC), shows how this process both decentralized scientific authority in India and led to changes in India's nuclear programme. New evidence presented from the deliberations of the Prime Minister's Secretariat (PMS) shows that Vikram Sarabhai, appointed chairman of the AEC in 1966, following the sudden death of the previous leader, Homi Bhabha, was the favoured candidate from the start of the process. His view on India's nuclear programme contrasted sharply with that of his predecessor, but his authority was protected, in part, from external challenge by the jurisdictional decisions made by the PMS. This article argues that the ambiguity inherent in India's developing nuclear programme was not the result of the apprehension of external threat, but the result of internal tensions within the relevant institutions, which are both revealed and (partially) resolved by the appointment process for the new chair.

In 1871, the Swiss physiological chemist Friedrich Miescher published the results of a detailed chemical analysis of pus cells, in which he showed that the nuclei of these cells contained a hitherto unknown phosphorus-rich chemical which he named ‘nuclein’ for its specific localisation. Published in German, ‘Ueber Die Chemische Zusammensetzung Der Eiterzellen’, [On the Chemical Composition of Pus Cells] Medicinisch-Chemische Untersuchungen (1871) 4: 441–60, was the first publication to describe DNA, and yet remains relatively obscure. We therefore undertook a translation of the paper into English, which, together with the original article, can be accessed via the following link https://doi.org/10.1017/S000708742000062X. In this paper, we offer some intellectual context for its publication and immediate reception.

Following some years of declining health, Professor Maurice Crosland passed away on 30 August 2020 at the age of eighty-nine. Author of four influential scholarly monographs, Maurice played major roles in the British Society for the History of Science during the 1960s and 1970s as an active Member of Council, Honorary Editor of the British Journal for the History of Science (1965–71) and Honorary President of the society (1974–6). His academic career began in 1963 with his appointment to a lectureship in the History & Philosophy of Science at the University of Leeds. In 1974 the by-then Reader in History of Science secured a £100,000 Nuffield Foundation Grant with which to establish, for the first time, a dedicated history-of-science group at the University of Kent at Canterbury. Appointed Professor of the History of Science and Director of the Unit for the History, Philosophy and Social Relations of Science (known as the ‘History of Science Unit’ or simply ‘the Unit’), his objectives during the five-year Nuffield-funded period were to focus on promoting the research activities of the new group, build up much-needed library resources in a university which was barely ten years old, and effect a transition to a research and teaching Unit that would offer modules to undergraduates in each of the three principal faculties (Humanities, Natural Sciences and Social Sciences). His own research centred on French science during and after the Napoleonic period, with particular emphasis on the history of chemistry and the formal institutions and informal networks of Parisian science. In 1984 his work was recognized with the American Chemical Society's award of the Dexter Prize, a rare achievement for a British scholar.

Robert Maxwell Young's first book Mind, Brain and Adaptation in the Nineteenth Century (1970), written from 1960 to 1965, still merits reading as a study of the naturalization of mind and its relation to social thought in Victorian Britain. I examine the book from two perspectives that give the volume its unique character: first, Young's interest in psychology, which he considered should be used to inform humane professional practices and be the basis of social reform; second, new approaches to the history of scientific ideas. I trace Young's intellectual interests to the Yale Philosophy Department, the Cambridge Department of Experimental Psychology and a new history and philosophy of science community. Although Young changed his political outlook and historiography radically after 1965, he always remained faithful to ideas about thought and practice described in Mind, Brain.

This article will reveal how local scientific determination and ambition, in the face of rejection by funders, navigated a path to success and to influence in national policy and international medicine. It will demonstrate that Birmingham, England's ‘second city’, was the key centre for cutting-edge biological psychiatry in Britain in the 1920s and 1930s. The ambitions of Frederick Mott – doyen of biochemistry, neuropathology and neuropsychiatry, until now celebrated as a London figure – to revolutionize psychiatric treatment through science, chimed with those of the City and University of Birmingham's Joint Board of Research for Mental Diseases. Under Mott's direction, shaped by place and inter-professional working, the board's collaborators included psychiatrist Thomas Chivers Graves and world-renowned physiologist J.S. Haldane. However, starved of external money and therefore fresh ideas, as well as oversight, the ‘groupthink’ that emerged created the classic UK focal sepsis theory which, it was widely believed, would yield a cure for mental illness – a cure that never materialized. By tracing the venture's growth, accomplishments and contemporary potential for biochemical, bacterial and therapeutic discoveries – as well as its links with scientist and key government adviser Solly Zuckerman – this article illustrates how ‘failure’ and its ahistorical assessment fundamentally obscure past importance, neglect the early promise offered by later unsuccessful science, and can even hide questionable research.
