In Memoriam: Andreas Engel We mourn the loss of Prof. em. Andreas Engel, who passed away on April 1, 2026, at the age of 82. Andreas Engel was not only an outstanding scientist and a pioneer in nano- and structural biology, but also one of the founding fathers of the Nanoscience degree pro- gram at the University of Basel nearly 25 years ago. Through his dedication and visionary leadership within the then newly established National Centre of Compe- tence in Research in Nanosciences (NCCR Nano), he played a key role in creating the interdisciplinary Bach- elor’s and Master’s programs that continue to inspire young talents to this day. At the time, educating students in an interdisciplinary way across the natural sciences from the very beginning was a true innovation – thanks to Andreas Engel, the first students successfully gradu- ated in nanosciences as early as 2005. Andreas Engel also remained closely connected to the successor organization of the NCCR Nano, the Swiss Na- noscience Institute (SNI). In recognition of his excep- tional commitment to the study program, he was awarded the honorary membership of the SNI in 2016. In addition, his distinguished research in the fields of atomic force microscopy and cryo-electron microscopy contributed to numerous projects. Above all, we have lost a warm, enthusiastic, and highly valued colleague. He cared deeply about the edu- cation of young scientists, personal interaction and in- terdisciplinary thinking – something many of us experi- enced once again at the anniversary celebration of the nanoscience program last year. We will always remember Andreas Engel with great gratitude.
