It is with great sadness that we learnt the death of Jacques Friedel on August 27^th 2014 at the age of 93.

Jacques Friedel, this great scientist, played a determining role, as well in the wide domain of the condensed matter physics as in the organization of the scientific and the training in France. He was also one of the men having contributed most to the development of the French industry and metallurgy.

His scientific work was entirely dedicated to the theoretical physics of solids, in particular to the study of the defects and the electronic structure of the metallic compounds.

EDP Sciences has had the honor to have him as author from 1953 in the Journal de Physique et le Radium until 2011 in EPL, publishing also numerous articles in the Journal de Physique, Journal de Physique Letters, the European Physical Journal B and the Revue de Métallurgie.

In 1989, EDP Sciences (formely "Les Éditions de Physique”) published the book "Jacques Friedel - Scientific Works” with a foreword of the Nobel Prize in physics Sir Nevill Mott, who wrote:

I end here a very incomplete account of his work. I have known Jacques Friedel as a shy young man at Bristol, rapidly gaining confidence as a physicist; as leader of solid state physics in France, building up a powerful group… I am proud and happy to have had some part in starting him on his way.

Our sincere condolences and deepest sympathies go to his family and loved ones.
