April 13, 1945

Otto Wolf (1927–1945), a Czech Jewish teenager, chronicled his family's experience living in hiding in rural Moravia during World War II. His journal began on June 22, 1942, the day he and his family escaped from an assembly center in Olomouc, Moravia, where they had been taken for deportation to Theresienstadt. Otto's last diary entry is dated April 13, 1945. On April 18, he was captured and arrested. He was shot two days later on April 20. His family did not know of his fate; his sister Felicitas began writing in his diary, keeping it up to date for his expected return.

Felicitas donated Otto's handwritten journals to the United States Holocaust Memorial Museum in 1995. The diary was published posthumously.
