“In 1941, shortly before Rosh Hashanah – just a month or so after I began working for Dr. Korczak – I had a conversation with him that I recall vividly. It was already quite late when Korczak asked me to speak with him. From outside, we could hear shooting. The children were asleep, and the lamp cast a light on his bent and tired figure.
Korczak asked me about my parents and my Jewish education. He told me that he wanted me to intensify my influence on the children. “I myself am lost,” he said, “but I am looking for a word of strength for my children and for myself. I am desperately looking for a prayer to G-d.” He sighed.
“Dear child”, he said to me, “please help the children. Show them your love for G-d. Share with them your trust in Him. Tell them about Rosh Hashanah. Tell them that G-d is so close that everyone can speak to Him. Do you promise?”
I did.
That Autumn, Korczak organized Rosh Hashanah and Yom Kippur prayers in the orphanage.”
