This project offers a new postwar history of human genetics, by examining how, in mid-twentieth century Britain, blood groups were made into objects for investigations into human heredity and diversity. It follows the collection of blood groups from communities around the world, the grouping of samples, their transformation into data, and their presentation as credible genetic knowledge. Archival sources, interviews, and published sources reveal the institutional infrastructures and community interactions through which geneticists acquired and exploited resources for research. Films, newspaper reports, pamphlets and books for broader audiences reveal the careful management of popular understanding of genetic research.

Blood group research in Britain
In early 1930s Britain a community of geneticists, including R.A. Fisher and J.B.S. Haldane, promoted blood groups as having the potential to give the study of human heredity ‘a solidly objective foundation, under strict statistical control’. Fisher and colleagues at the Cambridge Galton Serum Unit—especially Robert Race and Arthur Mourant—implemented this vision, the project shows, using the arrangements for large-scale blood transfusion set up early in World War II. After the war, Mourant became director of the Blood Group Reference Laboratory and Robert Race of the Blood Group Research Unit, both at the Lister Institute of public health in London. As well as standardising antisera and investigating blood-grouping problems for the World Health Organization, these laboratories collected, analysed and published vast quantities of genetic data, making the Lister the global centre for blood-group genetics.
 
Purified race science
Against a backdrop of intense international discussion about the meaning and scope of race science, many researchers including Mourant made blood group genetics exemplify a modern, ethically neutral and ‘scientific’ study of race. The project explores the ways in which blood groups were mobilised in political discourses both within the disciplines of genetics, anthropology and geography, but also in relation to international efforts to reform the study of race.
 
Resources for human genetics
Robert Race’s Blood Group Research Unit made use of its contacts with blood banks and hospitals around the world to obtain specimens of rare blood types and turned them into precious resources for the discovery and elucidation of rare new blood groups. Considering the value and uses of rare blood brings into view the work done to annotate blood groups, antibodies, genes and alleles, with individual, family and racial identities.
 
Nomenclatures
This project also offers the first sustained analysis of the functions of nomenclatures in genetic research. For over a decade Robert Race and his colleagues were embroiled in a fierce dispute over the most appropriate nomenclatures used to denote the Rhesus blood groups. Doctors, pathologists, geneticists and anthropologists around the world joined the debate. I use this controversy—which is not fully resolved to this day—to think about the ways in which geneticists visualised and negotiated their objects of research, and how they communicated and collaborated with workers in other settings. Extending recent studies of relations between different media, I consider the material forms of nomenclatures, as they were jotted in notebooks, printed in journals, scribbled on blackboards, and spoken out loud.
