It was an area of interwar Poland which had been annexed in 1939 by Nazi Germany as part of the new territory of Reichsgau Wartheland earmarked for complete "Germanization". In 1940 the Nazis created a ghetto in Izbica for 1,000–1,600 Jews.[3] On 12 January 1942 Winer was deported to Chełmno extermination camp, to slave labour with the camp's Sonderkommando.[4][5] Two days later, the Izbica Ghetto was liquidated through deportations of 900–1,000 others to extermination on 14–15 January 1942.
