Nazi hunter

A Nazi hunter is a private individual who tracks down and gathers information on alleged former Nazis, SS members, and Nazi collaborators who were involved in the Holocaust, typically for use at trial on charges of war crimes and crimes against humanity. Prominent Nazi hunters include Simon Wiesenthal,Tuviah Friedman, Serge and Beate Klarsfeld, Ian Sayer, Yaron Svoray, Elliot Welles, and Efraim Zuroff.

With the onset of the Cold War following World War II, both the Western Allies and the USSR sought out former Nazi scientists and operatives for programs such as Operation Paperclip. Cooperative former Nazis, such as Wernher von Braun and Reinhard Gehlen, were occasionally given state protection in return for valuable information or services. At the time, Gehlen had been chief of the German Bundesnachrichtendienst (federal intelligence agency), founder of the Gehlen Org and co-founder of the ODESSA network, which helped exfiltrate Nazis from Europe. Other Nazis used ratlines to escape post-war Europe to places such as Latin America.
