Alexander Jacobs was a son of Meijer Jacobs and Leentje Kokernoot. At the age of 24 he married 4 December 1941 in Amsterdam the 24-year old Rebecca Italiaander, a daughter of Eva Wagenhuizen's first marriage with Hartog Italiaander.
Up from early September 1942 Alexander Jacobs has been employed as forced laborer in the Jewish work camp Avegoor near Ellecom, (which later was named Palästina). Prisoners stayed there under bad conditions in villa Irene and they were terribly mistreated during the construction of a sports complex at a trainings center for Dutch SS.
End of November 1942 the work was done the the emaciated forced laborers, among them also Alexander Jacobs, were sent to Westerbork, where they were hospitalised on orders of the commandant.
On 4 January 1943, Jacob stayed in Westerbork in the penal barrack 67 and on 18 January 1944, he was put on transport to Theresienstadt, together with his wife Rebecca Italiaander. From there, Jacob was sent to Auschwitz on 16 May 1944 and later from there to Bergen Belsen, where he eventually lost his life in spring 1945. His wife Rebecca arrived from Theresienstadt in Bergen Belsen too, where she, according a surviving witness, lost her life about 15 April 1945
