**Histories of Computational Scientific Practices: Rolling out the Software Millefeuille** 2026 ESHS/HSS Joint Meeting - Edinburgh, Scotland - 13–16 July 2026 rsvp : 25 November 2025 Computational scientific practices have been sparking renewed interest. The aim of our call is to gather a community of Historians interested in reconstructing the development and uses of programs, libraries, algorithms and scientific software in different historical and cultural contexts ([Hocquet et al., 2024](https://www.nature.com/articles/s43588-024-00651-2)). The uses, sharing, maintenance, evolution of such scientific research artefacts are key elements in their life cycle and for the scientific communities that bring them to life. In this panel, we wish to focus on these life cycles. We welcome contributions that will present case studies addressing these computational practices and artefacts in all scientific fields, from punched cards to cloud services, whether these programs, libraries, algorithms and software are used for theorizing, modeling, simulating, predicting ([Johnson & Lenhard, 2024](https://direct.mit.edu/books/oa-monograph/5771/Cultures-of-PredictionHow-Eng...)), or within scientific instruments. What forms of recognition were associated with the actors developing these scientific artefacts? What was the interplay between scientific computational practices and their broader economical, political and sociocultural environments? What infrastructure was built and maintained? How were models, codes, programs, libraries, software packages, licensing policies layers intertwined? How were communities organized around the sharing, uses and reuses of such a millefeuille? What can we learn from contrasting and comparing situated computational practices across disciplinary perspectives, cultural premises and agendas of different communities? What kind of sources can we make use of for investigating computational scientific practices from the 1950s to the 2020s? We look forward to your contribution. Please submit your proposal consisting of a title and an abstract (up to 2000 characters) by replying to this email before **25 November 2025**.
