Who is the narrator from the story, Kaddish for a Child Not Born?

The narrator of Kaddish for a Child Not Born is a middle-aged Hungarian Jew who has survived the Holocaust. Survival has cost him a normal life. He is nihilistic (believes life is senseless and useless) and keeps to himself and his writing. His writing is his way of not existing in the real world, of digging the grave that was begun for him in Auschwitz. He cherishes this writing-as-grave-digging as his life work, grim as it is.
