Sarah Everts discusses different views of the chemists after twenty years after the fall of the Berlin such as Joachim Sauer, a computational chemist at Humboldt University believes that restrictions on free speech in current Berlin now seem unusual. The economic problems of the German Democratic Republic (GDR) led to the unavailability of research equipment. The GDR loosened restrictions on travel between East and West Germany before the wall had fallen. Ernst Schmitz, the former head of organic chemistry at the Academy of Sciences reveals that some researchers in the GDR were also forced to cooperate with industry. The huge investment by the German government in the former GDR led to strong research groups. Universities are smaller in the former GDR, but even when funding per professor is considered, the West is progressing.
