Mozes de Jong was a son of the commercial agent Izaak de Jong and Klaartje Polak. He was born 11 August 1896 in Amsterdam and married there on 25 February 1925 Judith Stad, a daughter of shopkeeper Joseph Stad and Elisabeth Scheffer. Mozes de Jong was in ladies fashon hats engros, was proxy holder, commercial correspondent, bookkeeper and he worked also as an agent on a basis of commission.
After the wedding, Mozes lived with his wife at Van der Helstplein 6 in Amsterdam till they moved in 1934 to Zuider Amstellaan 43 2nd floor. In 1935 they went to Jekerstraat 71 3rd floor but afterwards another three removals followed: in June 1939 to Zuider Amstellaan 71 1st floor; in January 1940 to Van Woustraat 173 1st stock and per 25 February to Amstellaan 38 3rd floor, this all in Amsterdam-South. As far as has been researched, the De Jong-Stad couple had no children.
Mozes De Jong was already taken to Westerbork, when he has submitted there – as can be deduced from his registration card of the Jewish Council – a request to the so-called “Antragstelle”, most likely a request for postponement of deportation. To that end, a “case handler” has been assigned to him. The “Antrag” (request) – as in most cases – was not honoured; his registration card was stamped per 1 October 1942 and already the next day, on 2 October 1942, Mozes de Jong was put on transport to Auschwitz. Also his father Izaak de Jong and his sister Elisabeth were deported to Auschwitz on that date.
This transport contained more than 1000 deportees and it was the first transport via the railroad from the camp. The train made a stop in Kozel, which was located about 80 km west from Auschwitz. There, 160 boys and men between 15 and 50 years were forced to leave the train, to be deployed as forced labourers in the surrounding labor camps. Those, who remained in the train were transported onwards to Auschwitz to be killed there; among those his father Izaak de Jong and his sister Elisabeth.
Mozes de Jong was part of the group of 160 men who had to leave the train and eventually he ended up in the "Reichsautobahnlager Annaberg", where he lost his life on 10 December 1942, due to diseases, hardship and the inhumane conditions there.
Because death certificates from the Annaberg and Niederkirch labor camps were found only in 2016, including those of Mozes de Jong, the Dutch authorities also had a death certificate drawn up for Mozes De Jong after the war, in which is official place and date of death were established as on 31 October 1943 in Schoppinitz Forced Labor Camp near Katowice in Poland.
Because it was previously not clear when and where Mozes de Jong had died, the official Dutch date of death will be maintained. The date on the Joods Monument is the legal date of death, as determined by the Ministry of Justice on 13 December 1951.
