Newcastle United Hebrew congregation is hosting an exhibition about the life of Janusz Korczak, a Polish doctor who perished in Treblinka. Mr Korczak had been working at a Jewish orphanage in Warsaw when the Nazis invaded Poland. Korczak and his orphanage were moved to the Warsaw Ghetto. Instead of protecting himself, he travelled with the 200 children when they were deported to Treblinka, where they were all killed. The exhibition is being staged at Newcastle UHC until May 11.
