David Koker

The diary was published in 1977 with the name Dagboek geschreven in Vught (Diary Written in Vught). The editor was Koker's best friend Karel van het Reve, a professor of Slavic languages and literature, who during the war collected and kept the smuggled diary pieces. The manuscript was stored at the Dutch Institute for War Documentation (NIOD). It has been translated into English and was published in 2012 under the title At the Edge of the Abyss: A Concentration Camp Diary, 1943-1944. Koker's Diary was in 2012 finalist for the Jewish Book Award in the Holocaust category.

David's mother and brother Max survived the war. David, however, fell ill and died during a transfer of ill people to the Dachau concentration camp due in part to his illness as well as hypothermia in February 1945. His father died of exhaustion in LangenBilau, a subcamp of Groß-Rosen.

On 2 June 1944, while the family was being transported to Auschwitz-Birkenau, David managed to throw a letter from the train, an excerpt of which read:

During his internment, he wrote a diary which was smuggled out of the camp, pieces at a time. The diary is maintained complete, starting on 11 February 1943 and ending on 8 February 1944. In addition to standard entries, David also used the diary to write poetry.

David was forced to halt his studies in philosophy and history in September 1941 when the university ceased allowing Jews to study anymore. The family did not go into hiding because they had received an exemption and believed they were safe. Still, in 1943, they were captured and transported to Camp Vught on 11 February. David spent some of his time teaching children at the camp. In July, he received a Sperre (temporary exemption from deportation) from Frits Philips and joined his "Philips Commandos". In June 1944, the "Philips-Jews" were transported to Auschwitz-Birkenau, from where they would be sent to other camps to work for electronic companies.

Koker had published in 1941 Modern-Hebreeuwse poëzie. The booklet (87 pages) was a bilingual edition of modern Hebrew poetry, with translations in Dutch. The co-translator was J. Melkman, pseudonym of Jozeph Michman (1914-2009). It was published by Joachimsthal in Amsterdam.

The Jewish student David Koker (27 November 1921 - 23 February 1945) lived with his family in Amsterdam until he was captured on the night of 11 February 1943 and transported to camp Vught.
