Have you ever noticed something about Adolf Hitler?

Hitler's paternal grandfather was probably one of the brothers Johann Georg Hiedler or Johann Nepomuk Hiedler. There were rumours that Hitler was one-quarter Jewish and that his grandmother, Maria Schicklgruber, became pregnant while working as a servant in a Jewish household. During the 1920s, the implications of these rumours were politically explosive, especially for the proponent of a racist ideology. Opponents tried to prove that Hitler had Jewish or Czech ancestors. Although these rumours were never confirmed, for Hitler they were reason enough to conceal his origins. According to Robert G. L. Waite in The Psychopathic God: Adolf Hitler, Hitler made it illegal for German women to work in Jewish households, and after the "Anschluss" (annexation) of Austria, Hitler had his father's hometown obliterated by turning it into an artillery practice area. Thus Hitler seems to have betrayed a fear of being Jewish. Waite says that Hitler's insecurities in this regard may have been more important than whether Judaic ancestry could have been proven by his peers.
