Dear colleagues, The So.Hist-Info seminar, coordinated by Mathilde Fichen, Camille Paloque-Bergès, and Adrien Tournier at the HT2S laboratory, and Léandre Bécard at COSTECH (UTC), invites you on *Monday, June 15, 2026, from 3:00 p.m. to 5:00 p.m.* at the *Cnam, 2 rue Conté (Paris FR) Room 30.-1.18*, for its *sixth and final session of the 2025-2026 season*. We will welcome *Amelie Mittlmeier* (Ludwig Maximilian University of Munich) for a presentation in English entitled: *Programming Languages and Communities of Programming* The speaker will discuss the importance of software in the historical formation and structuring of computing communities. To attend the seminar, please register here <https://framaforms.org/inscription-seminaire-de-socio-histoire-de-linformatique-1757664332>. A videoconference link will be sent to you upon registration. *Abstract:* The emergence of so-called high-level programming languages at the end of the 1950s not only marked a technological shift from earlier automatic coding systems but also gave rise to distinct communities of computing. Languages such as FORTRAN and ALGOL were not merely technical tools; they became focal points around which practitioners organized themselves, forming user groups and professional identities. In this sense, programming languages did not simply serve pre-existing communities – they actively contributed to their formation. As these communities developed, so too did debates about the relative merits of different programming languages. However, these discussions were marked by the absence of clearly defined and widely accepted criteria for evaluating programming languages. They reflected deeper disagreements about the nature of programming itself – whether it should be understood as a scientific discipline, an engineering practice, or even an artistic endeavor. This lecture asks why the question of the “best” programming language became such a relevant and persistent concern among experts - and why it lost its relevance at the end of the 1960s. It examines the debates between different language communities and analyzes how these controversies shaped both technological development and the emerging research field of programming. By situating these discussions in their historical context, the talk highlights how competition and disagreement contributed to deepening experts’ understanding of programming and thus to the formation of the field. *https://sohistinfo.github.io/ <https://sohistinfo.github.io/>* -- Institutional email address : camille.paloque_berges@cnam.fr *Laboratory for the History of Techno-Sciences (HT2S), Conservatoire national des arts et métiers, 2 rue Conté, 75003 Paris, France
