Sara Warszawski was born Sara Lewin on 22 September 1864 in Gnesen, Posen (now Gniezno). She lived for a time, probably with her husband, in an apartment at Tile-Wardenberg-Straße 30. On 4 April 1923, now a widow, she was allocated a one-room apartment with heating facilities on the fourth floor at Bundesratufer 2.
On 18 July 1942, she was forced to complete and sign a declaration of assets, enabling the German Reich to confiscate everything she owned. Ten days later, on 28 July 1942, she was deported from the assembly camp at Große Hamburger Straße 26 on the “31st transport of the elderly” to Theresienstadt. The Theresienstadt commemorative book notes that she was sent to Treblinka on 26 September 1942. She had turned 76 just four days earlier. The entire contents of her apartment were bought by a retail dealer, Friedrich Weigel, for 112 Reichmarks and sold on to “Aryan” residents.
