The senior experts go on excursions together. These events – preferably a mix of culture and chemistry – focus not only on exploring new horizons but also on social interaction between the seniors. In addition to the GDCh seniors, seniors from the VAA, Hanau-Wolfgang plant group, usually also participate in these excursions.
This first excursion on 23 May 2007 was organized by Holger Bengs; all subsequent tours were organized by Wolfgang Gerhartz, partly with strong support from Eva Wille, Klaus-Peter Jäckel and Hans-Uwe von Grabowski.
