Foreword ––– 3 Dear readers “Pioniergeist” – pioneering spirit – was the word that defined the launch of the Biozentrum 50 years ago. The groundbreaking idea was to bring together outstanding biologists, chemists and physicists under one roof and trust that they would determine how molecules generate life. Looking back, we can say that the Biozentrum has fulfilled and even exceeded these expectations: The institute has made transformative discoveries, spawned I was seven years old and lived in Birsfelden when the several Nobel Laureates, and trained thousands of Biozentrum was opened, and I still remember the excite- students and scientists to become leaders in academia, ment that surrounded the new institute in our region. biotech, business and society. Now 50 years later I again feel the same enthusiasm and “Pioniergeist”, because the Biozentrum has reinvented Many ingredients have contributed to the Biozentrum’s and rejuvenated itself. The 1971 founders have been success: A visionary mission and the freedom to address followed by a new generation that is as passionate and fundamental questions in biology; the generous support driven as their predecessors. And the move into our by university, government, industry and the public; and brand-new building will support cutting-edge research for Basel’s cosmopolitan culture and belief in the common years to come. In another 50 years the Biozentrum will good. But as you will read in this brochure, the main be renewed once again. In the words of Bob Dylan, the ingredient has been the people who have studied, Biozentrum will stay “Forever Young”. researched and worked here.

The Biozentrum’s golden jubilee ––– 8 The Biozentrum’s golden jubilee ––– 9 Biozentrum’s golden jubilee Greeting: Andrea Schenker-Wicki, President of the University of Basel Was it the driving force of a handful of Basel personalities? Was it the excellence of the University’s researchers? Or was it the exceptionally healthy public finances that made the opening of the Biozentrum possible 50 years ago? A look at the history of the Biozentrum’s origins offers an answer, which can be expressed very simply: It was, without question, a huge stroke of fortune – for The new Biozentrum building represents a key milestone on the path to the University of Basel’s Life Sciences Campus. Further new buildings are planned in the immediate vicinity of the University Hospital and the University Children’s Hospital on science, for business, and for the region’s inhabitants. the Schällemätteli Campus. These will provide premises for the Department of Biomedicine, the Natural Sciences and for ETH Zurich’s Department of Biosystems Science and Engineering (D-BSSE). Almost 800 million Swiss francs are being invested in cutting-edge infrastructure for the Life Sciences Campus in order to provide the optimal conditions for research and teaching.

Dr. Severin Schwan, CEO of Roche, Basel Happy 50th birthday Biozentrum!” “Many great minds have led to the outstanding success of the Biozentrum since its founding 50 years ago. We’re proud to note that one of the original initiators of the now world-renowned Biozentrum was Alfred Pletscher, Roche’s head of research at that time. Research-driven companies today enjoy the fruits of basic research done decades ago. The Biozentrum and other leading institutes Professor Catherine Dulac, Howard Hughes Medical will remain key to medical breakthroughs in applied research.” Institute, Harvard University, Cambridge, USA “The scientific creativity and productivity at the Biozentrum over the last 50 years have been nothing short of extraordinary. The remarkable scholar- ship and motivation of Biozentrum scientists and the outstanding diversity and quality of their scientific endeavors make the Biozentrum a towering institution in Europe and in the entire world. I wish the Biozentrum another 50 years of stellar accomplishments!” Dr. Vas Narasimhan, CEO of Novartis, Basel “Basel and the Rhine Valley have a rich history in life sciences and biomedical innovation, and the Biozentrum has helped carry that legacy forward, taking the visionary step 50 years ago to develop an interdisciplinary research facility.

Autor: Vorname Nachname Life Sciences ––– 3 Research A fascination for research Since its foundation, the Biozentrum has been passionately devoted to studying molecules, cells and organisms to achieve a deeper understanding of the fundamental principles of life. This pursuit transcends the boundaries between research fields or countries, as the overlap between completely different disci- plines is often where innovative ideas and research approaches are most likely to emerge.

There is still a lot of work to be done along those lines and I sincerely hope that this will continue to change in the future. Our brain is a network comprising some 200 billion neurons. These neurons feature numerous projections that connect them and enable them to communicate with each other.

Bibliometric data were provided by Max Hintermann from the University Library Basel.
