Torchlight procession to honor Prof. Alexander Koller

The student councils of LST and Computer Science jointly organized a torchlight procession to honor Professor Doctor Alexander Koller, supported by the Freunde der Saarbrücker Informatik (FdSI) and Friends of LST. The aim was to convince the professor, who has received a call from another university, to continue his teaching and research at Saarland University.
