The BIPM announces the death of Prof. Christian Bordé

Prof. Bordé made many eminent theoretical contributions to atomic interferometry and fundamental measurement science. He published some of the first studies that would later underpin the use of fundamental constants as the basis of definitions for the International System of Units (SI). He chaired the Comité science et métrologie at the Académie des sciences of Paris and contributed for many years to the activities of the CCU (Comité consultatif des unités).

Prof. Bordé was elected a corresponding member of the Académie des sciences in 1997 and a member in 2008. He presided (by delegation of its President) over the meetings of the General Conference on Weights and Measures (CGPM) in 1999, 2003, 2007 and 2011.

His death has been announced in Le Figaro.
