To the family's relief he died in 1903 at the age of 66, when Hitler was 14. Adolf adored his mother Klara, who was 23 yrs younger than Alois, to such an abnormal extent that it raises doubts about Adolf's Oidipus-complex. Hitler's mother died from breast cancer, when Hitler was 18 yrs old. Her mother's doctor was a Jew, Edouard Bloch. The same year when his mother died in 1907, Hitler tried to get into a Viennese art-acdemy, but failed in the entry-exams. The Academy's principal was a Jew. Homeless, penniless, an orphan and failed Hitler probably had become paranoid by it all and he started to accuse the Jews of his misery. Hitler had grandiose-complex, which kept him from seeing and accepting reality as it is. Therefore he sought reasons to his failures from outside of himself Unfortunately psychiatry had not yet developped sufficently so that symptoms of a disturbed mind could have been detected and so no-one stopped the "beast" from realising its sickness in practise.
