In the decades since Adolf Hitler’s death, the Nazi leader’s ancestry has been a subject of rampant speculation and intense controversy. Some have suggested that his father, Alois, born to an unwed woman named Maria Schickelgruber, was the illegitimate child of Leopold Frankenberger, a young Jewish man whose family employed her as a maid. (She subsequently married Johann Georg Hiedler–later spelled “Hitler”–whose surname her son adopted.)
Und die Jerusalem Post behauptet 2019 https://www.jpost.com/diaspora/study-suggests-adolf-hitler-was-a-quarter-jewish-597966:
[A] study by psychologist and physician Leonard Sax has shed new light supporting the claim that Hitler’s father’s father had Jewish roots.
The study, titled “Aus den Gemeinden von Burgenland: Revisiting the question of Adolf Hitler’s paternal grandfather,” which was published in the current issue of the Journal of European Studies, examines claims by Hitler’s lawyer Hans Frank, who allegedly discovered the truth.
Hitler asked Frank to look into the claim in 1930, after his nephew William Patrick Hitler threatened to expose that the leader’s grandfather was Jewish.
In his 1946 memoir, which was published seven years after he was executed during the Nuremberg trials, “Frank claimed to have uncovered evidence in 1930 that Hitler’s paternal grandfather was a Jewish man living in Graz, Austria, in the household where Hitler’s grandmother was employed,” and it was in 1836 that Hitler’s grandmother Maria Anna Schicklgruber became pregnant, Sax explained.
...
Sax writes in the study that according to the letters in Frank’s memoir, “Frankenberger Sr. sent money for the support of the child from infancy until its 14th birthday.”“The motivation for the payment, according to Frank, was not charity but primarily a concern about the authorities becoming involved: ‘The Jew paid without a court order, because he was concerned about the result of a court hearing and the connected publicity,’” the letters state.
Keine Beweise, aber auch nicht völlig unplausibel. Lawrow hat das auch eher vorsichtig ausgedrückt: "I may be mistaken but Adolf Hitler had Jewish blood, too."
Nun ja, journalistische Arbeit war von Bathon eh nicht zu erwarten.
