Herman von Klempt is a Nazi 'mad scientist' who has worked on numerous schemes to control or destroy the world. Though his body was destroyed, von Klempt survived as a head in a jar, often assisted in his work by his mechanical apes.
A German scientist, von Klempt was a close colleague of Karl Ruprecht Kroenen at university. Although the two men apparently shared similar ideas, von Klempt was not recruited by Grigori Rasputin as a disciple. Von Klempt was assigned to other Nazi projects.
