Jocelyne Jerdelet (1959 – 2017)

Jocelyne Jerdelet joined CERN in November 1983 as an operator in the Experimental Physics (EP) division analysing images of collisions produced by the detectors. Shortly thereafter, she joined the Scientific Information Service.

In that role, she worked on cataloguing preprints, which, at the time, the Library received in paper form. For a long time, she was involved in preparing the legendary “weekly list of preprints and reports”. Then, with the development of computer tools, the web and the arXiv preprint server, her work evolved and she contributed actively to the automation of these processes, allowing the Library to move from paper to the electronic realm. An article in the CERN Courier in 2002 paid homage to her competence and her contribution to the modernisation of the processing of scientific literature.

Thanks to her commitment, care and attention to detail, documents produced by the LEP and then the LHC collaborations were quickly made available on both the CERN Document Server (CDS) and Inspire – a crucial service for the CERN and global scientific communities.

In addition to her day-to-day work, she led a number of fundamental projects to successful conclusions. In particular, she coordinated one of the Library’s first large-scale digitalisation projects: that of the Theory department’s collection of preprints, which is one of CERN’s most prolific collections.

Jocelyne also trained numerous students, apprentices and even staff members, demonstrating patience and a talent for teaching. She knew how to transmit her knowledge, always with the aim of doing the job as well as possible. As well as being a consummate professional, she also displayed admirable personal qualities: her colleagues felt that they could rely on her and enjoyed working with her.

“Joce” was always calm and smiling, always ready to help. A local of the region, she loved nature and enjoyed walking in the Jura mountains.

We have lost a pillar of the Scientific Information Service and a dear friend, and we share her family’s grief at this difficult time.
