Holocaust survivor Samuel Geller recalls a more sober celebration than usual on Purim of 1933 in Chemnitz, Germany, with a classmate dressing up as Hitler to play Haman, Purim’s villain.

Jola Gelb is a Jewish Holocaust survivor who was imprisoned in the Metajna Concentration camp in Slana/Pag in today’s Croatia. More than 3,500 Jews, Roma and Serbs were held at Slana in the summer of 1941, and 1,000 were killed at a complex of camps run by the Ustasha regime. Researchers are using Jola’s testimony to help document and preserve the sites of persecution in Slana.
