Knowledge for Victory was a reunion of many scientists to talk about science. It took place in Berlin in July of 1903.
The reunion gathered over two hundred specialist from various fields. Apparently the conference's goal was to create better weapons for the Germans, but according to von Toten they didn't achieve much. Everything they were able to create crumbled to dust, because the technology was still imperfect.
After the conference disbanded and everyone left for their homes, 96 participants went missing. They were specialist from chemistry, physics, engineering, mechanics, linguistics and even a philosopher. Von Toten did not went missing. Since he was one of the most important people out there, that was quiet odd. Proably this lead to the IAGH suspecting him.
