Bernard Gregory

Bernard Paul Gregory (19 January 1919 – 24 December 1977) was a prominent French physicist and director-general of CERN.

During World War II, Gregory was a prisoner of war in a German camp for military officers. Gregory returned to France. He became known in the high energy physics world in the 1950s when he worked as a researcher, with the title of deputy director, under Professor Leprince- Ringuet at the École Polytechnique. At the École Polytechnique he worked with a number of physicists including , Jean Crussard (1911-1986), André Lagarrigue, and later André Astier.

In 1958, Gregory was appointed professor of physics at Polytechnique. At CERN, he supervised most of the construction of the world's first hadron collider, the Intersecting Storage Rings (ISR).

Following his mandate as CERN Director-General, Gregory returned to the Polytechnique laboratory in Paris. Soon he became director-general of the National Center for Scientific Research (CNRS), which he led from 1973 to 1976. He was elected president for the CERN Council for 1978, but died before entering this position.

There is a street, Route Gregory, named after Gregory at the CERN Meyrin site.
