Yitzhak Zuckerman (; ; 13 December 1915 – 17 June 1981), also known by his nom de guerre "Antek", was one of the leaders of the Warsaw Ghetto Uprising in 1943 against Nazi Germany during World War II. Biography Zuckerman was born in Vilnius, partitioned Poland (then part of the Russian Empire, now the capital of Lithuania) into a Jewish family. As a young man he embraced the concepts of socialism and Zionism. After the German and Soviet invasion of Poland in 1939 he was in the area overrun by the Red Army and initially stayed in the Soviet zone of occupation, where he took an active part in the creation of various Jewish underground socialist organisations. In the spring of 1940 he moved to Warsaw, where he became one of the leaders of the Dror Hechaluc youth movement, along with his future wife Zivia Lubetkin. Zuckerman was issued a false passport by the Ładoś Group. In 1941 he became the deputy commander of the ŻOB resistance organisation. In this capacity, he served mainly as the envoy between the commander of ŻOB and the commanders of the Polish resistance organizations of Armia Krajowa and Armia Ludowa. On 22 December 1942 he and two accomplices attacked a café in Kraków that was being used by the SS and Gestapo. Zuckerman was wounded and narrowly escaped, and his two comrades were tracked down and killed. In 1943, he was working on the "Aryan" side of Warsaw to procure guns and ammunition when the Warsaw Ghetto Uprising erupted. Unable to enter the ghetto to join his comrades in battle, he nonetheless proved a crucial link between resistance forces within the ghetto and the Home Army on the "Aryan" side. Along with Simcha "Kazik" Rotem, he organized the escape of the surviving ZOB fighters through the sewers to safety. During the later Warsaw Uprising of 1944, he led a small troop of 322 survivors of the Ghetto Uprising as they fought the Germans in the ranks of the Armia Ludowa. After the war he worked as part of the Bricha network, whose operatives smuggled Jewish refugees out of Eastern and Central Europe to Mandate Palestine. In 1947 he himself made that journey, settling in what would soon be Israel. There he and his wife Zivia, along with other veterans of the ghetto undergrounds and former partisans, were among the founding members of Kibbutz Lohamei
