Janusz Korczak (pen name of Henryk Goldszmit, 1878–1942) trained as a physician at the University of Warsaw before dedicating his life to child welfare. He directed the Dom Sierot orphanage for Jewish children from 1912 until its liquidation by the Nazis in 1942, developing the institutional practices — children's parliaments, peer courts, student-run newspapers — that became the philosophical foundation for the 1989 UN Convention on the Rights of the Child. His major works include How to Love a Child (1919), The Child's Right to Respect (1929), and the children's novels King Matt the First (1923) and Kaytek the Wizard (1933). On August 5 or 6, 1942, he refused multiple offers of personal escape and accompanied approximately 192 children from his orphanage to Treblinka, where they were all murdered. UNESCO established the Janusz Korczak Chair in his honor, and his legacy continues to shape global discourse on children's rights, education, and the ethics of care.
Born into a progressive Warsaw Jewish family, Korczak adopted his pen name from the winning entry of a literary contest and kept it through a double career: physician by day, writer and educator by night. He served as a military doctor in the Russo-Japanese War (1904–1905), the First World War, and the Polish-Soviet War (1919–1921), experiences that deepened his commitment to children as the primary casualties of adult catastrophe.
From 1934 to 1936, Korczak hosted a weekly radio program as "the Old Doctor," one of the earliest examples of mass-media parenting advice and a platform for his children's rights philosophy. The program was cancelled as antisemitism intensified in Polish public life during the late 1930s. By the time of the German invasion in September 1939, Korczak was sixty-one, internationally known as an author, and increasingly isolated as Poland's Jewish intellectuals faced mounting persecution.
The orphanage was forced into the Warsaw Ghetto in November 1940. Korczak maintained the institution's democratic structures through the ghetto years, even as food, space, and hope contracted. His Ghetto Diary — written in the final months, hidden in the orphanage walls, and recovered after the war — documents an extraordinary refusal to abandon either the children or the framework he had built around them. The diary ends in early August 1942. Shortly thereafter, Korczak, Stefania Wilczyńska, the other staff, and all the children were deported and murdered.
Korczak's influence on contemporary AI ethics is indirect but consequential. The UN Convention on the Rights of the Child — directly descended from his 1929 essay — provides the formal basis for nearly every international framework on children and digital technology, including UNICEF's Policy Guidance on AI for Children. His insistence on the child's present-tense dignity, on the developmental necessity of struggle, and on the adult obligation of accompaniment has become the most rigorous available framework for evaluating what AI systems do to the children who use them.
Born July 22, 1878 (some sources record 1879) in Warsaw to Józef Goldszmit, a lawyer, and Cecylia Gębicka. Educated at the University of Warsaw medical faculty, graduating 1903. Adopted the pen name Janusz Korczak from a novel by Józef Ignacy Kraszewski. Founded Dom Sierot in 1912 with Stefania Wilczyńska. Served multiple military tours as a physician. Published prolifically across medical, educational, and children's literature genres for four decades. Died at Treblinka in August 1942.
Dual training. Korczak's unusual combination of medical and pedagogical expertise gave his children's rights framework an empirical grounding that purely theoretical approaches lacked.
Writer and practitioner. His books emerged from daily practice at Dom Sierot; the writing and the institutional work were inseparable.
The 1942 refusal. Korczak's decision to accompany the children to Treblinka was consistent with four decades of practice, not a departure from it.
Posthumous influence. Korczak's framework became the philosophical foundation for international children's rights law, though his name remains less widely recognized than his ideas.
