Abraham de Leeuw, born on 6 August 1921 in Amsterdam to Hartog de Leeuw and Cato Bloemhof, was unmarried. He worked as a forwarding clerk, continued to live at home with his parents, until he was already taken to Westerbork on 18 July 1942, registered there on July 19th and then deported to Auschwitz on 24 July. He was then almost 21 years old.
The first transports from Westerbork to Auschwitz mainly consisted of young men, who were deported to Eastern Europe under the guise of "Arbeitseinsatz" in Germany. Later transports also contained women and children.
Upon arrival in Auschwitz on July 27, Abraham was most likely selected to be put to work as a forced laborer inside or outside the camp. It is not known where, nor what kind of “work” he had to do, nor is known the exact date Abraham de Leeuw died.
After the war, Dutch Authorities have established, also based on testimonies of survivors and research of the Red Cross, that Abraham de Leeuw no longer could be alive after 30 September 1942.
The Dutch Ministry of Justice then ordered the City of Amsterdam to draw up a death certificate for Abraham de Leeuw, in which it was established that he died on 30 September 1942 in Auschwitz. (This is actually standard for most Dutch Jews who have arrived in Auschwitz between 15 July 1942 and 30 September 1942).
