Samuel Joseph Pos was born 3 January 1888 in Paramaribo and a son of Joseph Hendrik Pos and Jansje van West. He had a brother, Hartog Joseph, who has left Suriname for Holland in 1910 and arrived in Hoorn, where he established himself as a dentist at Grote Oost 2. His brother married in Winterswijk in 1913 Martha Elzas and in 1914 their son Herman was born.
On 18 December 1913 also Samuel Joseph Pos arrived in The Netherlands and lived for a short time with his brother Hartog and sister-in-law in Hoorn. Just as his brother, also Samuel Joseph was a dentist by profession. On 26 February 1914 he left Hoorn for Alkmaar, where he has lived more than two years at the address Laat 223. On 24 July 1916, the still unmarried Samuel Joseph Pos moved to Den Haag, where he started in the Hugo de Grootstraat 57 but on 29 April 1933 he established himself as a dentist at the Waldeck Pyrmontkade 129, which at the same time would become his last known address in Den Haag.
The measures of the German occupier against the Jewish population of Den Haag, started in the first year of the war. Their rights were curtailed month after month. In May 1941, dentist S.J. Pos advertised in the “Joodsche Weekblad” (Jewish Weekly), that he held consultations for Jewish patients from 1-3 hours. A new all time low was reached in the summer of 1942. Then the occupier decided that all Jews had to leave Den Haag. Subsequently, between August 1942 and April 1943, the majority of the Jews from Den Haag were deported to Westerbork and from there to extermination camps. The first roundups in Den Haag took place on 22 August 1942.
Samuel Joseph Pos also met that fate; on 28 November 1942 he was carried off to Westerbork and put on transport to Auschwitz on 8 December. On arrival there on 11 December 1942, he was killed immediately in the gas chambers of Auschwitz-Birkenau.
