Karl Ernst Krafft (10 May 1900 – 8 January 1945) was a Swiss astrologer, born in Basel. He worked on the fields of astrology and graphology.
After graduating from university in mathematics, for the best part of ten years he worked on a massive book entitled Traits of Astro-Biology. This expounded his own theory of "Typocosmy": the prediction of the future based on the study of an individual's personality, or type. By the early 1930s, when Hitler had come to power, Krafft enjoyed a unique status among occultists and prophets in Germany. The National Socialists, later to become his patrons, at first posed a threat to him. Occultists, like Freemasons, were among those harassed and vilified by most National Socialists.
While the Nazi state persecuted astrologers, Rudolf Hess and Heinrich Himmler consulted them. Krafft moved into the orbit of the National Socialist elite in November 1939 when he made a remarkable prediction. He predicted that the Führer's life would be in danger between 7 and 10 November. He wrote, on 2 November to a friend, Dr Heinrich Fesel, who worked for Himmler, warning him of an attempt on Hitler's life. Fesel filed the letter away, unwillingly to become enmeshed in something dangerous.
On 8 November, a bomb exploded at the Munich beer hall. There were many injuries but the target, Adolf Hitler, was unscathed because he left the assembly in the hall a few minutes before the explosion. When newspapers reported the near-catastrophe Fesel dispatched a telegram to Hess, drawing attention to Krafft's prediction. Krafft was arrested and brought to Gestapo Headquarters in Berlin. Krafft's proclamation of exacting astrological rules managed to convince the Gestapo that astrology enabled its practitioners to make accurate forecasts of future events resulting in now being employed by the Nazi Propaganda Ministry, the SS and even the Foreign Office to carry out astrological studies of a political nature. After his release he was summoned to the Reich Propaganda ministry, run by Dr Joseph Goebbels. Goebbels had recently taken to poring over Nostradamus, trying to squeeze propaganda from the prophecies. Krafft, he felt, should work on deciphering the cryptic quatrains. In January 1940, Krafft began work on a pro-German evaluation of Nostradamus.
