Concealment
Under another name, Josef Mengele spent three years doing farm labor near his home region. Manual work replaced the scientific career he expected.
The escape route
A childhood friend, Hans Sedlmeier, helped maintain contact and recover his research materials. In spring 1949, Josef Mengele crossed the Alps toward Italy.

A new identity
Josef Mengele traveled through forest routes into South Tyrol, adopting the name Helmut Gregor. Each border crossed separated him further from his former life.
Passage purchased
In Genoa, a smuggler arranged the paperwork and passage to South America. The journey relied on money, aliases, and networks rather than any lawful refuge.

Inspection
Josef Mengele reached Argentina as Helmut Gregor with an International Red Cross travel document. Medical specimens and research papers in his luggage nearly exposed his identity.
Sanctuary
A port doctor accepted his explanation that he was an amateur biologist. He passed through customs and entered a country where displaced Nazi fugitives could find contacts.

Legal normalization
After years using false identities, Josef Mengele sought official German papers through the consulate. Officials processed his disclosures without meaningfully investigating his record.
Respectable cover
Argentina issued a residence permit, and he obtained a German passport under his real name. The return to legality strengthened his business life but made him easier to identify.
