Part of the project of reweaving the threads of the history of the Third Reich, the essay discusses the complex relation between the testimony of the victims and their body as an epistemic source of the witnessing. On a theoretical bases constructed with the help of Shoah memoirs – by Primo Levi, Jean Améry, Jorge Sempun, Robert Antelme, and others, the paper challenges the notion of the witness as a speaker, a narrator; instead, it treats the kind of victim that since Auschwitz has been known as “a Muselmann” as an integral witness. It is the body of the survivor that constitutes integral testimony; it fills a testimonial lacuna. The presence of the Muselmann is testifiable, and it can replace the memoir by the body as the repository of the event. When the body translates into the corpus of writing, survivor testimony is perceived as incomplete so long as the Muselmann is perceived as the other. The lacuna in survivor narratives is testimony from inside the experience of the Muselmann.
