Krystyna Adolph (died 30.03.1987) lived with her husband and daughter in Ignalin near Troki (Lithuania). Before 1939 she worked as a history teacher at the Duke Adam Czartoryski Secondary School in Vilnius. When the war broke out, she was widowed and had to look after her daughter and the farm on her own. In a difficult situation Krystyna was able to find courage to help those in need. When the Germans occupied Vilnius in 1941, she told her former Jewish pupils, sisters Monika and Lidia Głuskin, that she would give them shelter in her house in case of danger. After the Vilnius ghetto was established, the girls took her up on her offer. They hid in Krystyna’s house for more than 3 years, helping Adolph with the housework and the farm. The Głuskin sisters were introduced to the neighbours as relatives who had hidden with Krystyna from the forced labour. Their true identity was only known to a few people from the family of the teacher’s late husband, who had supported her during the war. The woman knew very well what she was risking by giving shelter to her former pupils because in the neighbouring village, the German gendarmes had burnt down the house together with the family who had been hiding the Jews. The hardship and danger of hiding the Jewish girls did not stop Krystyna, so the girls managed to survive until liberation. Adolph also helped the girls’ mother, Luba Gluskin, obtain forged documents which enabled her to leave the ghetto and hide on the Aryan side. After the war, the Głuskin sisters emigrated to Israel, from where they remained in contact with their occupation guardian for many years.

On 14 May 1984, the Yad Vashem Institute honoured Krystyna Adolph with the title 'Righteous Among the Nations’ in recognition of her heroism during the Holocaust.
