Hitler's Family: In The Shadow Of The Dictator (2006)
Adolf Hitler consistently hushed up or denied his family lineage for fear that his ragtag bunch of ancestors and living relatives could tarnish his reputation or expose his imperfect Aryan background. His family had a history of psychiatric disorders, and his second cousin, Aloisia Veit, was locked up in an asylum for nine years before being sent to the gas chambers for being "unworthy of life".
Hitler was embarrassed by his sister Paula, and made her live under the assumed name of Paula Wolf. Paula became engaged to Dr Erwin Jekelius, medical director of the asylum who sent hundreds of mentally ill patients, including Aloisia Veit, to their deaths.
Nazi propaganda portrayed Adolf Hitler as a man minus family or private life. As a matter of fact, he kept in touch with his family--mainly to control them. There was shady half-brother Alois, a Berlin innkeeper who tried to profit from his name, and half-sister Angela, in charge of housekeeping at the Berghof retreat, who had neighbors chased away. His niece Geli, who called her uncle a "jailer", committed suicide. His "favorite nephew" was educated at an elite Nazi school. His sister Paula wanted to marry a surgeon and mass murderer. And his English-born nephew William Patrick, a playboy in Berlin, extorted money by threatening to expose family secrets. We present previously unknown documents and personal records and descendants of the Hitler family talk about living in the shadow of a dictator.
