Nazi hunter

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 Federal Intelligence Service or Bundesnachrichtendienst (federal intelligence agency), founder of the Gehlen Org, "a true life version of ODESSA"[3] network, which helped exfiltrate Nazis from Europe.

[4][5] In response, Nazi hunters sought out fugitives on their own or formed groups, such as the Simon Wiesenthal Center.

Methods used by Nazi hunters include offering rewards for information,[6] reviewing immigration and military records,[7] and launching civil lawsuits.

[7] In later decades, Nazi hunters found greater cooperation with Western and South American governments and the state of Israel.
