We foresee two days of exciting science to honour the multifaceted career of our friend and colleague Bernard Julia.

Bernard has made many significant contributions to science, amongst which the description of supergravity in eleven dimensions (with Eugene Cremmer and Joël Scherk), the Julia-Zee dyon as well as dualities in supergravity. Bernard's contributions have been farsighted.

Our conference will take place in the Darboux amphitheater of the Institut Henri Poincaré in the rue Pierre et Marie Curie in Paris.

We acknowledge generous support by the Fédération de Recherche : Interactions Fondamentales, the Department of Physics and the Laboratory of Physics at the École Normale Supérieure, and the Institut de Physique Théorique Philippe Meyer.
