Cold Moves: Cryogenics in Indo‐German Research Networks**

Abstract

AbstractBy unravelling the complexities and dynamics of a collaboration between scientists in India and West Germany to establish a cryogenic network, this paper intends to contribute to our understanding of the transnational movement of research technologies during the Cold War. In 1971, a cryogenic laboratory including a helium and a nitrogen liquefier was set up at the physics department of the Indian Institute of Technology (IIT) Madras as part of the Indo‐German partnership at IIT Madras between 1959 and 1974. As a generic research technology with many applications, cryogenics became crucial for a solid state research agenda for semiconductor development. After initial difficulties, Ramaswami Srinivasan at IIT Madras and Gustav Klipping of the Fritz Haber Institute in Berlin built a successful collaboration based on mutual trust and on Indian and German scientists travelling and working in each other's laboratories. If the initial motivation of the Indo‐German partnership was informed by the logic of Cold War development policy, Klipping and Srinivasan developed their collaboration into a vibrant cryogenic research network around different actors, instruments, and skills moving between India and the Federal Republic of Germany.
