Eichmann played a key role in the Holocaust

The passport was issued by the Red Cross, in the Italian city of Genoa, under the name of Ricardo Klement.

The student found the passport among court documents while investigating Eichmann's capture in 1960 by the Israeli secret service.

He was tried and sentenced to death in Israel in 1962 for his role in mass killings of Jews during World War II.

At the end of the war Eichmann, one of the main architects of the Holocaust, was among the most wanted men in Europe.

He was captured a couple of time but managed to escape allied forces, fleeing Europe. Five years after the end of World War II, he arrived in Argentina which at the time provided a safe haven for many Nazi war criminals.

The false passport that has now come to light gives details of "Ricardo Klement", the name Eichmann used to pose as a stateless refugee.

"Ricardo Klement" was born in Bolzano, in northern Italy, and was a mechanic by profession.

Wife's complaint

The passport contains a photograph of a bespectacled, balding man who is dressed in a shirt and jacket, and bears a fingerprint in red ink.

The document was issued by the International Committee of the Red Cross in Genoa and was stamped by the Argentine consul general in the city.

Eichmann was seized by Israeli agents in 1960 and taken to Israel, where he was tried and hanged.

His wife went to the Argentine courts to denounce his kidnapping, handing over his passport and admitting his real name.

The passport was discovered in court archives by a student doing research and has now been handed over to Argentina's Holocaust Museum in Buenos Aires.
