Szlama Ber Winer
Szlama Ber Winer, nom de guerre Yakov (Ya'akov) Grojanowski (23 September 1911 – c. 10 April 1942), was a Polish Jew from Izbica Kujawska, who escaped from the Chełmno extermination camp during the Holocaust in German-occupied Poland. Szlamek (the diminutive form of Szlama) is sometimes incorrectly referred to as Szlamek Bajler in literature by the surname of his nephew, Abram Bajler, from Zamość (see postcard).
