History of computing at CERN

CDC 3800, 1966The history of computing at CERN is about hardware, software, people, network, communications, accelerators, data-handling...

This section is an eclectic stockpile of material covering various aspects of the computing history at CERN. It is by no means a complete history, and new elements are added all the time as they come to light. 

For photographs, see the IT Archive Galleries, the CERN PhotoLab Archives, and the 'Photos from..." (in the column to the right of this page). The "IT Archive Galleries" and CERN PhotoLab Archives are work-in-progress; more material is being added all the time as we dig deep into forgotten archives.

For more information on CERN's computing history, contact our Computing History at CERN (aka Cath Noble) for help.

Overview

See the excellent presentation by David Williams from CHEP 2004 for a comprehensive and revealing look at Computing at CERN since CERN's inception in 1954.
