On 8. December 2025, 20 years of the Worldwide LHC Computing Grid (WLCG) were celebrated at CERN with a festive workshop. WLCG is the federated IT-infrastructure that transforms the massive amounts of data of the LHC experiments into scientific knowledge and impact. WLCG was a major part of the success of finding the Higgs-Boson in 2012, which resulted in the physics Nobel Prize a year later. We at SCC are part of WLCG with the Grid Computing Centre Karlsruhe (GridKa), the German Tier-1 data center, since the beginning.
The program of the workshop comprised presentations from the early founding fathers, e.g., Leslie Robertson (CERN retired), Simon Lin (ASGC Taiwan, retired) and Fabrizio Gagliardi (ex-CERN, retired) showing impressive insides and historic slides how everything started. A view into the future was given by Mark Thomson (CERN Director-General Designate) and Karl Jakobs (University of Freiburg and Chairman of the European Strategy for Particle Physics Group).
