Irena Sendler. An unfamiliar name to most people, but this remarkable woman defied the Nazis and saved 2,500 Jewish children by smuggling them out of the Warsaw Ghetto. As a health worker, she sneaked the children out between 1942 and 1943 to safe hiding places and found non-Jewish families to adopt them.Some children were taken out in gunnysacks or body bags. Some were buried inside loads of goods. A mechanic took a baby out in his toolbox. Some kids were carried out in potato sacks, others were placed in coffins, some entered a church in the Ghetto which had two entrances. One entrance opened into the Ghetto, the other opened into the Aryan side of Warsaw. They entered the church as Jews and exited as Christians. "`Can you guarantee they will live?'" Irena later recalled the distraught parents asking. But she could only guarantee they would die if they stayed. "In my dreams," she said, "I still hear the cries when they left their parents."But the Nazis became aware of Irena's activities, and on October 20, 1943 she was arrested, imprisoned and tortured by the Gestapo, who broke her feet and legs. She ended up in the Pawiak Prison, but no one could break her spirit. Though she was the only one who knew the names and addresses of the families sheltering the Jewish children, she withstood the torture, refusing to betray either her associates or any of the Jewish children in hiding.Sentenced to death, Irena was saved at the last minute when Zegota members bribed one of the Germans to halt the execution. She escaped from prison but for the rest of the war she was pursued by the Gestapo.After the war she dug up the jars and used the notes to track down the 2,500 children she placed with adoptive families and to reunite them with relatives scattered across Europe. But most lost their families during the Holocaust in Nazi death camps.The children had known her only by her code name Jolanta. But years later, after she was honored for her wartime work, her picture appeared in a newspaper. "A man, a painter, telephoned me," said Sendler, "`I remember your face,' he said. `It was you who took me out of the ghetto.' I had many calls like that!"Irena Sendler did not think of herself as a hero. She claimed no credit for her actions. "I could have done more," she said. "This regret will follow me to my death."
