Explore the resources prepared for press for important events in CERN's history.
Find out when CERN's accelerators were commissioned and built – and when beams circulated inside them for the first time.
CERN's first computer was a Dutchman named Wim Klein. How things have changed.
From early experiments with electricity to detectors in space: Find out about the history of research into cosmic rays
The positron - the antimatter counterpart of the electron - was discovered in a cloud chamber in 1932. The particle is still making tracks today

The On-Line Isotope Mass Separator ISOLDE is a facility dedicated to the production of a large variety of radioactive ion beams
In early 2013, the CERN accelerator complex shut down for two years of planned maintenance and consolidation. The work prepared the accelerators and experiments for running the LHC at the higher energy of 13 TeV.
Find out when CERN's member states joined the organization.
The Protocol Office is a service to the Directorate. An average of 160 dignitaries visit CERN each year from approximately 60 nations. Since the birth of the Organization in 1954 CERN has been proud to welcome more than 70 Heads of State, 30 Heads of Government, and about 600 Ministers, 645 Ambassadors and Heads of International Organisations, and 174 groups of Members of Parliament to mention but a few. This timeline is a list of the nationals who have visited from individual states.
From a cavern 100 metres below a small Swiss village, the 7000-tonne ATLAS detector is probing for fundamental particles in collisions from the Large Hadron Collider.
Follow the story of the web from its inception at CERN to the global phenomenon we know today.
CERN has come a long way since its foundation in 1954. This timeline collects the organization's major contracts, projects, partnerships and scientific advances.
LEP – the largest electron-positron accelerator ever built – was dismantled in 2000. Its 27-kilometre tunnel now hosts the LHC
The LHC is the largest machine in the world. It took thousands of scientists, engineers and technicians decades to plan and build, and it continues to operate at the very boundaries of scientific knowledge.
The Higgs boson is the final piece of the puzzle in the Standard Model – finding it with the LHC would be a momentous result. But not finding it could be even more exciting.
To find the W boson, CERN converted Europe's largest accelerator, the Super Proton Synchrotron, into the world's first proton-antiproton collider. The bold move paid off
Over the years CERN has hosted many world-class experiments on antimatter. Follow the research from first observations to the latest breakthroughs.
