Julianne Nyhan will seek to 'represence' the role of gender and invisible labour in the incunabular DH. Between 1954–1967, the Index Thomisticus project, an influential project in the early years of the field of Humanities Computing, had a workforce that numbered, at its peak, about 65 individuals. Yet many of those who worked in this project, especially the young women handling the project data, remain absent from histories of the development of DH. As her forthcoming book (Nyhan 2023) explores, these labour absences were neither inconsequential nor thoughtless, but can be understood to distill processes of exclusion/inclusion and expressions of social and epistemological hierarchy that would shape not only the emerging field of humanities computing, and in due course DH, but aspects of the wider development of computing too.
