Answer
Pan Doktor, meaning "Mr. Doctor," was the affectionate nickname given to Janusz Korczak, a renowned Polish-Jewish physician, educator, and children's rights advocate. He dedicated his life to caring for orphaned and disadvantaged children, establishing orphanages where he implemented innovative educational methods that emphasized respect, dignity, and self-governance. Korczak's unwavering commitment to children's well-being and his tragic fate during the Holocaust have made him an enduring symbol of compassion and selflessness.
