By the end of the month, arrangements for Freud's own departure for London had become stalled, mired in a legally tortuous and financially extortionate process of negotiation with the Nazi authorities. Under regulations imposed on its Jewish population by the new Nazi regime, a Kommissar was appointed to manage Freud's assets and those of the IPA whose headquarters were near Freud's home. Freud was allocated to Dr. Anton Sauerwald, who had studied chemistry at Vienna University under Professor Josef Herzig, an old friend of Freud's. Sauerwald read Freud's books to further learn about him and became sympathetic towards his situation. Though required to disclose details of all Freud's bank accounts to his superiors and to arrange the destruction of the historic library of books housed in the offices of the IPA, Sauerwald did neither. Instead he removed evidence of Freud's foreign bank accounts to his own safe-keeping and arranged the storage of the IPA library in the Austrian National Library where it remained until the end of the war.
