I just read this article on Yahoo news, and it blew me away---I can't do any better, so I'll just re-copy it here:
Polish Holocaust hero dies at age 98

WARSAW, Poland - Irena Sendler — credited with saving some 2,500 Jewish children from the Nazi Holocaust by smuggling them out of the Warsaw Ghetto, some of them in baskets, died
Monday, her family said. She was 98.
Sendler, among the first to be honored by Israel's Yad Vashem Holocaust memorial as a Righteous Among Nations for her wartime heroism, died at a Warsaw hospital, daughter Janina Zgrzembska told The Associated Press.
President Lech Kaczynski expressed "great regret" over Sendler's death, calling her "extremely brave" and "an exceptional person." In recent years, Kaczynski had spearheaded a campaign to put Sendler's name forward as a candidate for the Nobel Peace Prize.
Sendler was a 29-year-old social worker with the city's welfare department when Germany invaded Poland in September 1939, launching World War II. Warsaw's Jews were forced into a walled-off ghetto.
Seeking to save the ghetto's children, Sendler masterminded risky rescue operations. Under the pretext of inspecting sanitary conditions during a typhoid outbreak, she and her assistants ventured inside the ghetto — and smuggled out babies and small children in ambulances and in trams, sometimes wrapped up as packages.
Teenagers escaped by joining teams of workers forced to labor outside the ghetto. They were placed in families, orphanages, hospitals or convents.
Records show that Sendler's team of about 20 people saved nearly 2,500 children from the Warsaw Ghetto between October 1940 and its final liquidation in April 1943, when the Nazis burned the ghetto, shooting the residents or sending them to death camps.
"Every child saved with my help and the help of all the wonderful secret messengers, who today are no longer living, is the justification of my existence on this earth, and not a title to glory," Sendler said in 2007 in a letter to the Polish Senate after lawmakers honored her efforts in 2007.
In hopes of one day uniting the children with their families — most of whom perished in the Nazis' death camps — Sendler wrote the children's real names on slips of paper that she kept at home.
When German police came to arrest her in 1943, an assistant managed to hide the slips, which Sendler later buried in a jar under an apple tree in an associate's yard. Some 2,500 names were recorded.
"It took a true miracle to save a Jewish child," Elzbieta Ficowska, who was saved by Sendler's team as a baby in 1942, recalled in an AP interview in 2007. "Mrs. Sendler saved not only us, but also our children and grandchildren and the generations to come."
Anyone caught helping Jews in Nazi-occupied Poland risked being summarily shot, along with family members — a fate Sendler only barely escaped herself after the 1943 raid by the Gestapo.
The Nazis took her to the notorious Pawiak prison, which few people left alive. Gestapo agents tortured her repeatedly, leaving Sendler with scars on her body — but she refused to betray her team.
"I kept silent. I preferred to die than to reveal our activity," she was quoted as saying in Anna Mieszkowska's biography, "Mother of the Children of the Holocaust: The Story of Irena Sendler."
Zegota, an underground organization helping Jews, paid a bribe to German guards to free her from the prison. Under a different name, she continued her work.
After World War II, Sendler worked as a social welfare official and director of vocational schools, continuing to assist some of the children she rescued.
"A great person has died — a person with a great heart, with great organizational talents, a person who always stood on the side of the weak," Warsaw Ghetto survivor Marek Eldeman told TVN24 television.
In 1965, Sendler became one of the first so-called Righteous Gentiles honored by the Yad Vashem Holocaust memorial in Jerusalem for wartime heroics. Poland's communist leaders at that time would not allow her to travel to Israel; she collected the award in 1983.
Yad Vashem Chairman Avner Shalev said Sender's "courageous activities rescuing Jews during the Holocaust serve as a beacon of light to the world, inspiring hope and restoring faith in the innate goodness of mankind."
Despite the Yad Vashem honor, Sendler was largely forgotten in her homeland until recent years. She came to the world's attention in 2000 when a group of schoolgirls from Uniontown, Kan., wrote a short play about her called "Life in a Jar."
It went on to garner international attention, and has been performed more than 200 times in the United States, Canada and Poland.
Sendler, born Irena Krzyzanowska, said she lived according to her physician father's teachings, arguing that "people can be only divided into good or bad; their race, religion, nationality don't matter."
She married Mieczyslaw Sendler but they divorced after the war's end. Sendler then married fellow underground activist Stefan Zgrzembski, and they had two sons and a daughter. One died a few days after birth. The second son, Adam, died of a heart failure in 1999.
Sendler is survived by her daughter and a granddaughter.
