Bruno Weymuller (HF 1971-72) was a graduate of the Ecole Polytechnique and the Ecole des Mines de Paris when he awarded a French Harkness Fellowship. It took him to the Massachussetts Institute of Technology (MIT), where he obtained a Master of Science. Robert Solow supervised his thesis, on “Control theory and macroeconomic consequences”. Back in France he joined in the civil service. In 1978 he was appointed to the Cabinet of the Prime Minister, Raymond Barre, as counselor for Industry and Scientific Research. In 1981, he moved to the international oil major Elf Aquitaine (now Total). There he occupied different management positions in the Upstream and Finance Divisions, ending as executive vice-president for strategy and risk assessment, and a member of the Group Executive Committee. For his various contacts in industrial and financial circles in the United States, over many years, he benefited greatly from the experience he had acquired as a student at MIT and travelling from coast to coast during the summer of 1972, with two English Fellows, both still very good friends. He remains deeply grateful to the Foundation for this exceptional transatlantic opportunity. Now retired, he is, inter alia, member of the bureau of the association “Amis du musée franco-américain de Blérancourt”. This museum, located in the former property of Anne Morgan, daughter of J.P. Morgan, pays tribute to her support for France during the First World War in the form of a medical infrastructure to help the injured, and after 1918 in the form of a decisive contribution to the reconstruction of villages neighbouring Blérancourt. Bruno’s Fellowship experience encouraged his elder son, Charles Henri, to study for a PhD in economics at Harvard, partly thanks to which he now works as an adviser to the President of the French Republic, Emmanuel Macron.
