Einstein reached the pinnacle of his profession not in 1932, when he moved to Princeton, but in 1914, when he was appointed Professor at the University of Berlin, Director of the Kaiser Wilhelm Institute for Physics and a member of the Prussian Academy of Sciences. Even the finest scientists produced by Cambridge felt obliged to do a tour of duty in Germany. There was, however, another Germany - a Germany of provincial hometowns that felt no affection for the frenzied modernism of the Grossstadt. This Germany had been traumatized by the upheavals that had begun with the ghastly revelation of military defeat in November 1918. Nearly all the revolutionary events of the immediate post-war period took place in the big cities: Berlin, Hamburg, Munich. Despite the decision to draft the new republic's constitution in the sleepy capital of Thuringia, the Weimar Republic was always a metropolitan affair.
