My name is Jacques M. Connan. I am a chemical engineer from the Ecole Nationale Supérieure de Chimie de Strasbourg and a PhD (Docteur es Sciences Physiques) of the Strasbourg University. With Pierre Albrecht, we were the pioneers in Organic Geochemistry in France, and I completed my career at the French oil company Elf Aquitaine. I finished this career as an international expert in Petroleum Geochemistry at Total. I have been also Director of Research in CNRS and Professor at the Strasbourg University. I have published 270 papers and received five awards: Prime à innovation Elf Aquitaine: pionnier en géochimie organique, Prix E. Piot de l’Académie des Inscriptions et Belles-Lettres for achievements in archaeometry, Prix Barbier de la Société Géologique de France, Prime à l’innovation: profession innovateur at Elf Aquitaine. Tribute paid by the Latin-American Association of Organic Geochemistry for a significant contribution to the development and spreading of Organic Geochemistry in Latin-America.
