On July 18, 1942, four days before the start of the Great Deportation of Jews from the Warsaw Ghetto, the residents of its orphanage produced a performance. Janusz Korczak, the orphanage’s famed director, chose the Bengali poet-philosopher Rabindranath Tagore’s poem Dak Ghar (The Post Office) for the youngsters. It depicts the narrative of a dying orphan child who, due to a fatal illness, is cut off from the rest of the world and must learn to live via his imagination. According to reports, Korczak thought that the play would teach the kids how to deal with death with grace.
