Yehiel De-Nur felt that "Yehiel Feiner" was destroyed in the Holocaust, and so he wished to destroy the book he published before the Holocaust
Author Yehiel Feiner, born in 1909, is known as one of the greatest authors to write about the Holocaust and its aftermath. Feiner renamed himself Yehiel De-nur and later chose a pen name imbued with meaning: Ka-Tsetnik 135633, taken from KZ – the short form the Nazis used for “Konzentrationslager,” German for concentration camp. The name therefore literally meant – “Concentration camp prisoner number 135633”
Before the Holocaust, in 1931, Yehiel Feiner published a book of Yiddish poetry titled “Twenty-Two” (צווייאונצוואנציק in Yiddish). After the war, any time he heard there was a copy of the book available at the National Library of Israel, Ka-Tsetnik would come to the Library, borrow out the book, and destroy it. Ka-Tsetnik did this three times between 1953 and 1993.
In 1953 and 1964 he burned the available copies of his book. In 1993, he wrote a letter to Shlomo Goldberg, the manager of the library stacks at the time, about the third and last time he destroyed the book. He shredded the publication and sent the remains of the book together with the letter in an envelope to Goldberg.
“I have another request: I placed here the remains of the ‘book.’ Please, burn them as my world and everything I loved burned in Auschwitz’s crematorium.”
It seems that Yehiel De-Nur felt that Yehiel Feiner had been destroyed in the Holocaust, along with everything dear to him. Moreover, De-Nur viewed everything Feiner created before the Holocaust as meaningless. As far as he was concerned, the Holocaust had utterly destroyed the world that existed before. Ka-Tsetnik, writing after the Holocaust, had nothing to do with Feiner and the work he created and published.
During Eichmann’s trial where De-Nur was a witness, Ka-Tsetnik called Auschwitz “another planet”. For Ka-Tsetnik there were three distinct worlds, before the Holocaust, during the Holocaust, and after the Holocaust and everything that he had created before the Holocaust could not be tolerated.
Yehiel De-Nur passed away on July 17, 2001. The Library still holds an intact copy of the book De-Nur tried so hard to destroy.
