With deep regret, we have to announce that our retired colleague Jean Renaud passed away on Monday, 9 January at the age of 76. Jean joined CERN in 1969 where he worked first in the Intersecting Storage Ring Division.

In the second half of his career, he was the senior principal technician in DELPHI, and later in the LHCb experiment, responsible for the integration and installation at the experimental site of both experiments until his retirement in 2005. It is thanks to the outstanding competence and dedication of people like Jean that we succeed in building and running our large detectors.

His friends and colleagues from DELPHI and LHCb.
