Janusz Korczak

Janusz Korczak, the pen name of Henryk Goldszmit, was a Polish Jewish pediatrician, educator, children's author and pedagogue known as Pan Doktor or Stary Doktor. He was an early children's rights advocate, in 1919 drafting a children's constitution. After spending many years working as a principal of an orphanage in Warsaw, he moved in with his orphans when the orphanage was forced to move to the ghetto, despite pleas from friends to flee the country.
