Krystyna Danko, née Chlond (9 July 1917 – 6 August 2019), was a Polish orphan from the town of Otwock, daughter of Karol Chlond – a respected city official in prewar Poland – who was awarded the title of Righteous among the Nations by Yad Vashem in 1998, for saving the lives of Polish Jews during the Holocaust while risking her own life at the time of the Nazi German occupation of Poland.
Krystyna Danko received her medal at the request of Maryna (Maria) Barton, née Kokoszko, whom she "smuggled" into a safer place from Otwock to Warsaw, where Maryna's extended family could take care of her.
Unafraid of endangering her own life, Krystyna helped her Jewish friends by giving them food she bought, clothing as well as money, and by fulfilling their heartfelt requests.Several years before the outbreak of World War II, Krystyna Danko established a close friendship with Lusia, the eldest daughter of the Kokoszko family, who was her high school classmate.
Krystyna spent a great deal of time in their home.
Once the Holocaust began, she did everything in her power to help the family survive the Nazis.
