Izaak Aleetrino was a son of Abraham Aletrino and Sara Finsij. He was born 31 October 1907 in Amsterdam and worked in the financial department of a newspaper. He married 23 June 1932 in Amsterdam Bertha Bloemendaal, a daughter of Levie Bloemendaal and Judikje Keizer. Izaak and Bertha had one daughter in 1936, named Rita Judith, who survived the Holocaust; her parents however were killed during the Shoah.
Izaak still lived at home with his parents in the Miquelstraat 28 in Amsterdam, when he married Bertha Bloemendaal. After his wedding in June 1932, he moved into an own home with her in the Kromme Mijdrechtstraat 35 2nd floor in Amsterdam-South, where their daughter Rita Judith was born in 1936. On 19 March 1940 the moved to Van der Waalsstraat 107 parterre in the Watergraafsmeer district, lived in from 18 till 27 March 1941 with his parents-in-law, Levie Bloemendaal and Judikje Keizer at Willem Beukelsstraat 2 upperhouse, after which the family left for Ermelo and Vierhouten in the province of Gelderland, possibly to investigate hiding places at the Veluwe. In April 1941 they returned to Amsterdam where they then came living at Galvanistraat 6 upperhouse in de district of Watergraafsmeer in Amsterdam.
The archive of the Jewish Council shows that the Izaak Aletrino family had gone into hiding. Not known is whether this was as a family and where, or that their daughter was brought into hiding elsewhere. She eventually has survived the war. It is clear – as stated on the registration cards of the Jewish Council of Isaac and Bertha - that after their arrest they both were imprisoned and from there on 17 February 1943 were sent to concentration camp Vught as “Häftlinge”(prisoners). On 31 March 1943 they were transferred to Westerbork and from there deported to Sobibor on 20 April 1943. On arrival on 23 April 1943, Izaak Aletrino and Bertha Bloemendaal were immediately killed in gas chambers there.
