Abstract
Manfred Eigen turned 90 on May 9th, 2017. He celebrated with a small group of colleagues and friends on behalf of the many inspired by him over his lifetime-whether scientists, artists, or philosophers. A small group of friends, because many-who by their breakthroughs have changed the face of science in different research areas-have already died. But it was a special day, devoted to the many genius facets of Manfred Eigen's oeuvre, and a day to highlight the way in which he continues to exude a great, vital and unbroken passion for science as well as an insatiable curiosity beyond his own scientific interests. He continues to dismiss arguments such as, that scientific problems cannot be solved because of a current lack of appropriate tools, or because of the persuasion of the community that certain things are immeasurable. He has lived up to and accepted only the highest scientific standards with his fundamental contributions in widely differing research fields, for which he has received numerous prizes and honorary doctorates, including the Nobel Prize for Chemistry in 1967. Some of his outstanding contributions to science and technology are honored in the following chapters. Here, we will report some characteristic traits of Manfred Eigen, and his personal development. We highlight his visionary foresight regarding how multidisciplinary science should combine to study the complex processes of life and its evolution in establishing an institute that applied biological, chemical, and physical methods, and how his vision became sustained reality.
