This article is concerned with the history of eugenic sterilisation in Britain through the 1920s and 1930s. In this period, the Eugenics Society mounted an active but ultimately unsuccessful campaign to legalise the voluntary surgical sterilisation of various categories of people, including those deemed ‘mentally deficient’ or ‘defective’. We take as our explicit focus the propaganda produced and disseminated by the Eugenics Society as part of this campaign, and especially the various kinds of data mobilised therein. The parliamentary defeat of the Society’s Sterilisation Bill in July 1931 marks, we argue, a significant shift in the tactics of the campaign. Before this, the Eugenics Society framed sterilisation as a promising method for eradicating, or at least significantly reducing the incidence of, inherited ‘mental defect’. Subsequently, they came to emphasise the inequality of access to sterilisation between rich and poor, (re)positioning theirs as an egalitarian campaign aimed at extending a form of reproductive agency to the disadvantaged. These distinct phases of the campaign were each supported by different kinds of propaganda material, which in turn centred on very different types of data. As the campaign evolved, the numbers and quantitative rhetoric which typified earlier propaganda materials gave way to a more qualitative approach, which notably included the selective incorporation of the voices of people living with hereditary ‘defects’. In addition to exposing a rupture in the Eugenics Society’s propagandistic data practices, this episode underscores the need to further incorporate disabled dialogues and perspectives into our histories of eugenics.

This article examines the career of pioneer British psychoanalyst David Eder (1865–1936). Credited by Freud as the first practising psychoanalyst in England, active in early British socialism and then a significant figure in Zionism in post-war Palestine, and in between an adventurer in South America, a pioneer in the field of school medicine, and a writer on shell-shock, Eder is a strangely neglected figure in existing historiography. The connections between his interest in medicine, psychoanalysis, socialism and Zionism are also explored. In doing so, this article contributes to our developing understanding of the psychoanalytic culture of early twentieth-century Britain, pointing to its shifting relationship to broader ideology and the practical social and political challenges of the period. The article also reflects on the challenges for both Eder’s contemporaries and his biographers in making sense of such a life.
