To get a sense of the scale of this operation, we have this excerpt from Michael Barenbaum's book, The World Must Know. The policy of extermination involved every level of German society and marshaled the entire apparatus of the German bureaucracy. Paris churches and the interior ministry supplied the birth records that defined and isolated Jews. The post office delivered the notifications of definition, expropriation, denaturalization, and deportation. The finance ministry confiscated Jewish wealth and property. German industrial and commercial firms fired Jewish workers, officers, and board members, even disenfranchising Jewish stockholders. The universities refused to admit Jewish students, denied degrees to those already enrolled, and dismissed Jewish faculty.
