Gratitude to the Heidelberg University faculty.

Thank you for leading Germany's oldest university with a bench scientist's rigor since 2023, and for a research career, from Marburg to the discovery-rich years in SUMO biology, that shows your community what excellence looks like up close.

Thank you for revealing how inhibitory interneurons conduct the brain's orchestra, synchronizing the networks that let us learn and remember, and for leading clinical neurobiology in Heidelberg for over two decades.

Thank you for building the cell culture systems that made hepatitis C druggable; the cures that now eliminate the virus in 95 percent of treated patients stand on the foundations your lab laid.

Thank you for giving a neglected millennium of Egyptian history its voice back, reconstructing the Book of the Temple and patiently indexing texts no one else could read.

Thank you for turning gold, long thought catalytically dull, into one of organic chemistry's most elegant tools, and for building the Heidelberg-BASF catalysis lab where academia and industry make chemistry together.

Thank you for showing that molecules, too, can melt into a Bose-Einstein condensate, and for building quantum systems atom by atom so we can watch many-body physics emerge from the very few.

Thank you for coaxing dysprosium atoms into quantum droplets and supersolid states, discoveries that let us hold in the lab forms of matter theory barely dared to predict.

Thank you for carrying forward one of mathematics' deepest traditions in the town where you earned your doctorate, and for advancing Iwasawa theory and explicit reciprocity laws with work the number theory world builds on.

Thank you for studying how climate, energy, and environmental policy actually work across countries, giving governments evidence instead of guesswork when they design the policies our common future depends on.

Thank you for working out how chaperones fold and rescue proteins in the crowded chaos of a living cell, insight that underpins how we understand stress, aging, and disease.

Thank you for a lifetime spent arguing that tax law should be simple enough for a citizen to understand, and for the years on the Federal Constitutional Court in which you helped keep Germany's Basic Law a living document.

Thank you for making gravitational microlensing a working telescope for the invisible, weighing dark matter and finding distant planets with nothing but bent light, and for two decades of leadership at the Astronomisches Rechen-Institut.
