On October 15, 2026, the Fortran programming language reached a significant milestone: 70 years since the publication of its first manual. Since its inception, Fortran has served as a foundational tool for scientific computing, supporting critical infrastructure and technological progress in diverse fields. Its applications are particularly prominent in nuclear engineering, materials science, and weather and climate forecasting, where it remains a primary choice for researchers and engineers.
This logo represents the language being celebrated for its 70th anniversary and its enduring legacy in scientific research.
To commemorate this anniversary, the Institute of Computing for Climate Science (ICCS) will host a 'Celebrating 70 years of Fortran' event at the Science and Industry Museum in Manchester, United Kingdom, on December 1, 2026. The event is designed as a retrospective, featuring a keynote address from Damian Rouson of the Lawrence Berkeley National Laboratory. The program includes 'lightning talks' on current community initiatives and an open breakout discussion focused on the future of the language over the next 70 years. The workshop is supported by sponsors including AMD, Dell Technologies, CAKE, OpenMP, and the ICCS.
Despite its age, Fortran continues to evolve and maintain relevance in modern high-performance computing. While early versions faced limitations—such as a six-character identifier limit and the lack of native string support—modern Fortran is noted for its efficiency in linear algebra and numerical calculations. The upcoming celebration aims to bridge this history, moving from the era of experimental computers like the 1940s 'Baby' to contemporary developments in simulation solvers and climate modeling. Registration for the event is available for both in-person and remote attendance via Zoom, with a focus on honoring the language's contributions to advancing human knowledge through computation.
