Lea Bierman was the daughter of Mozes Bierman and Rosalie de Leeuwe. She was born on 18 January 1909 in Amsterdam and worked as a domestic servant. On 28 September 1932, she married Mozes Blog in Amsterdam, who was born there on 24 June 1906 as the son of Coenraad Blog and Roosje Stodel. Lea and Mozes had a son on 4 June 1934, named Coenraad.
The Blog-Bierman couple lived at Plantage Muidergracht 41 2nd floor in Amsterdam, but their marriage did not last. From February 1942 Lea Bierman no longer lived together with her husband but stayed at the Noorder Amstellaan 161, where she had found accommodation with Eliazer de Jongh and his wife. On 14 May 1942, the marriage was officially dissolved by divorce and at the end of May 1942, Lea moved to Christiaan de Wetstraat 16 2nd floor, where her brother-in-law Jozef Karl Goedhart lived since 1939, who was married to her sister Vrouwtje Bierman.
Her son Coenraad, now 8 years old, lived with his father shortly after the divorce but was soon placed with his grandparents Coenraad Blog and Roosje Stodel. In December 1942 he stayed as a child in hiding in the Colson children's home at Johannes Verhulststraat 45 ground floor and somewhere in early 1943 also in the Brinkgreven Foundation in Deventer.
From the data of his registration card of the Jewish Council it appears that Coenraad ended up in the men's ward of the camp hospital of Westerbork on 13 April 1943; the hospital was located in barrack 6. From there he was deported on 18 May 1943 to Sobibor, where he was murdered on arrival on 21 May 1943.
However, Lea Bierman herself was already registered in Westerbork per 13 July 1942 and deported to Auschwitz on 16 July. On arrival there she was selected as a forced laborer, but it is not known where she was put to work nor the date she lost her life there. That is why, after the war, the Dutch Ministry of Justice ordered the Municipality of Amsterdam to draw up a death certificate for Lea Bierman, in which was established that she has died in Auschwitz on 30 September 1942.
