Switzerland will make the beginning in 2010 by inviting a German scholar to hold a lecture series in Switzerland. GDCh will invite a Swiss scholar to Germany in 2011, and so on. Edgar Heilbronner (1921–2006) was a Swiss German chemist. Erich Hückel (1896–1980) was a German physicist and physical chemist. The initiative arose from a cooperation agreement, signed by the two societies in 2008.
