Nearly two-thirds of the Holocaust Handbooks - based on page volume and principal authorship - can be credited to a single figure. If this weren't bad enough, it's none other than Carlo Mattogno, a prime example in the "How Not To Do History" playbook. It's truly comforting to know that the bulk of revisionist historiography rests on him.
Take Holocaust Handbook no. 23 on the Chełmno (Kulmhof) extermination camp, for instance. It's one of Mattogno's worst contributions, though the competition is fierce. In this work, a lack of proper historical method combines with near-total avoidance of research of the subject and unfortunate timing.
Mattogno sums up his approach in a single statement, which begs to be quoted in its full beauty:
"As there are no documents which can be used as a basis of comparison, this means that for Chełmno the testimonies cannot constitute historical sources, so that there cannot even exist a genuine historiography for this camp."
(Mattogno, Chelmno, p.9)
There's more than half a million words of witness accounts, hundreds of wartime documents, photos, and archaeological studies on the camp. Among all events of mass violence in human history, the extermination camp Chełmno (Kulmhof) is relatively well documented. But why let overwhelming evidence get in the way?
