Janusz Korczak
The Second Polish Republic had been annexed by Nazi Germany beginning on 6 October 1939. In October 1940, a ghetto meant to imprison Jews was established in Warsaw, and all of the Jews from Warsaw, including Korczak and the children from his orphanage, lived there. A new orphanage was built for the children in the ghetto. The deportation of Jews from the ghetto began on 22 July 1942. On 5 or 6 August 1942 in the Warsaw Ghetto, Germans came to collect the orphans from Korczak's orphanage and staff members from the orphanage in order to transport them to Treblinka extermination camp, while Korczak had been offered a job in the ghetto. In a well-popular act of both courage and loyalty, Korczak courageously refused the offer and wanted to board the train with the children from his orphanage, and told the German officers:  The children were dressed in their best clothing, and each carried a blue-colored backpack and a favorite book or toy. On the journey to the train station, one of the Schutzstaffel officers recognized Korczak as the writer of one of his favorite books. The officer offered Korczak to help him escape. But Korczak still refused. So, Korczak ended up boarding the train with the children and staff members to  the Treblinka extermination camp. This act of courage and loyalty, is what made Korczak very famous and popular in the modern-day world.
