This thesis compares the different trauma received at the three major hiding places for Jewish children in Belgium during the Holocaust: Christian establishments, private families, and Jewish orphanages. Jewish children hidden at Christian establishments received mainly religious trauma and nutritional, sanitary, and medical neglect. Hiding with private families caused separation trauma and extreme hiding situations. Children staying at Jewish orphanages lived with a continuous fear of being deported, because these institutions were under constant supervision of the German occupiers. No Jewish child survived their hiding experience without receiving some major trauma that would affect them for the rest of their life. This thesis is based on video interviews at Shoah Visual History Foundation and Blum Archives, as well as autobiographies published by hidden children.
