Meanwhile, the ever efficient German's already had a solution to the staffing problem.

Pre-heating of such an oven should take at least two days. After this preheating the oven will not need any more fuel due to the heat produced by the corpses. It will be able to maintain its necessary high (p.124) temperature through self-heating. But to allow it to maintain a constant temperature, it would have become necessary to introduce at the same time so-called well-fed and so-called emaciated corpses, because one can only guarantee continuous high temperatures through the emission of human fat. When only emaciated corpses are incinerated, it will be necessary to add heat continuously.

On 10 May 1933, students at the University of Berlin threw 25,000 books on a large pyre located in the square in front of the university. In the days that followed, gleeful students mounted book burnings at all the major universities in Germany. Newspapers from as far afield as China and Japan printed photographic and descriptive images of this violence. The world sensed that some kind of terrible rupture of civilization was taking place in the country of Dichter und Denker (poets and philosophers). Not a few journalists remembered the poet Heinrich Heine's prediction a century earlier: ‘Where one burns books, one soon will burn people’.
