Reinhard Kopps (29 September 1914 in Hamburg – 11 September 2001 in Bariloche, Argentina) was an SS officer for the Nazi Party during World War II. Following the defeat of Germany in World War II, he helped Nazis escape to Argentina, finally fleeing there himself. Under the assumed name of Juan Maler, Kopps was hiding in the small town of Bariloche in the Andes Mountains. Bariloche was the home of many Germans after World War II.
