The Contestation of Penal Expertise in the Age of the Expert: Thorsten Sellin and the Death Penalty in the 1950s

Abstract Readings of the history of penal expertise trace its rise to the late nineteenth century and its decline to the late twentieth century, with the crumbling of the welfare state. Despite stark differences along Whiggish and Foucauldian lines in evaluations of that history, a consensus has emerged that the penal-welfare complex peaked around mid-century, dependent on correctional experts. Most studies of that phenomenon have focused on the institutionalization and “treatment” of “problem” populations while neglecting the role of penal expertise in critiques of capital punishment. When Britain and Canada undertook major inquiries into the death penalty in the 1950s, they turned to the world’s foremost expert on the subject: sociologist Thorsten Sellin. Yet, these government-appointed studies devalued his academic capital in favor of the lived expertise of police. By examining the contestation of Sellin’s sources, methods, and conclusions, this paper puts the chronology of penal welfarism and its experts into question. Not simply a case of ill-informed opinion prevailing over criminological evidence, the dismissive treatment of this penal expert highlights the need to apply a more capacious understanding of contending forms of expertise at numerous points in penal history, rather than setting the devaluation of penal expertise in the recent past.
