75 Years of INFN

75 Years of INFN. A Story of Research, Innovation and Community 7 August 2026 The Istituto Nazionale di Fisica Nucleare (INFN, National Institute for Nuclear Physics) was established on 8 August 1951, 75 years ago, by decree of the National Research Council. Building on the legacy of Enrico Fermi, the Institute was founded on a strong scientific tradition in order to continue, after the war, the research he had initiated in the 1930s together with his school, the Via Panisperna Boys. Marking this anniversary is also a dedicated postage stamp from the thematic series The Excellence of Italy’s Cultural Heritage, issued on 8 August 2026. This recognition pays tribute not only to the history of INFN, but also to the contribution of Italian fundamental physics, now represented by a community acknowledged among the most authoritative at the international level. INFN Foundation Act, 1951. Synchrotron, the first high-energy accelerator built in Italy at the INFN National Laboratories of Frascati. The history of INFN is the story of a community devoted to scientific research that, over the course of 75 years, has succeeded in transforming major questions about nature into new knowledge, technologies and infrastructures. From the construction of the first particle accelerators to participation in major international experiments, from the national laboratories to applications of fundamental research, it is the story of a community that builds the future of science and culture every day. The history of INFN is the subject of an editorial project that tells the story of the Institute’s people, discoveries and places through the website “INFN History”, which covers a century of history beginning in the 1920s (only Italian version) The story, however, continues into the present day From 2020 to the Present Day: The Future Is Built in the Present Results in Neutrino Physics Elusive and
