He was among several survivors who testified against John Demjanjuk, by then a naturalized US citizen, who was suspected of having been a notorious Trawniki, or guard at Treblinka known as "Ivan the Terrible".

(Demjanjuk was later convicted of charges in Germany related to his documented service at the death camp Sobibor.)

It was published in Spanish in Uruguay in 1997 as Un grito por la vida: memorias ("A cry for life: memories").

As tensions increased in Europe, he said good-bye to his brother Moniek in 1939, encouraging him to flee to the Soviet Union.

With the work-permit issued by the Judenrat on German orders, Rajchman was sent to live and work in Ostrów Lubelski, in eastern Poland.

He was rounded up on October 10, 1942, along with other ghetto inmates, loaded onto a Holocaust train, and sent to Treblinka extermination camp.

Upon his arrival there the following day, Rajchman was separated from his sister Anna (she died at the camp), and put to work with the Jewish Sonderkommando.

Later he extracted gold teeth from dead victims at the Totenlager and disposed of thousands of their bodies, mostly by burning.

On March 12, 1980, he was interviewed by the Office of Special Investigations of the US Department of Justice about the Trawniki men, Treblinka guards drawn from Soviet prisoners of war.

Rajchman's testimony contributed to Demjanjuk's conviction, although he was later released on appeal because new evidence about his identity was found in newly declassified Soviet archives made available to researchers.

The memoir was published in French in 2009 by Les Arènes under the title Je suis le dernier Juif (I am the last Jew).
