Jacob van Spier, born on 1 January 1893 in Nijmegen, was a son of Jozef van Spier and Frederika Wolff. On 16 September 1919 he married Elisabeth Frank in Amsterdam. She was born on 21 July 1893 as a daughter of Salomon Frank and Catharina Frank. After their wedding ceremony, Jacob and Elisabeth went living in the Sint Annastraat 80 in Nijmegen. Jacob was live stock trader by profession. The couple had no children.
Jacob van Spier would have been involved in the betrayal of Jews during the war in collaboration with Nijmegen police officers. His house was vacated on 12 April 1943 and Jacob and his wife were transported to concentration camp Vught. On that same day he committed suicide on the train to Vught by ingesting poison. (Archive of Vught concentration camp, death register1943, death certificate:"Freitod durch Vergiftigung" - suicide by poisoning).
It appears from the Jewish Council registration card of Elisabeth Frank that has been transferred on 7 June 1943 from Camp Vught to Westerbork. From there, she was deported on 8 June to Sobibor, where on arrival on 11 June 1943, she was immediately killed in the gas chambers there.
