From the laudation: “Professor Dr. Ahmed El Goresy of Mainz was awarded the Abraham Gottlob Werner Silver Medal in recognition of his outstanding scientific contributions to the mineralogy of extraterrestrial rocks. Ahmed El Goresy is an internationally highly respected scientist who has made important, and in many cases pioneering, contributions to fundamental questions in cosmochemistry over more than 40 years. (...) The exceptional skills in reflected-light microscopy that Ahmed El Goresy acquired from his mentor Paul Ramdohr, together with his application of new microchemical methods, must be regarded as the foundation of his scientific achievements. The extraordinary productivity of Ahmed El Goresy in recent years is remarkable and demonstrates once again that innovative and creative research is not limited by age.”
