“The notion of a Jewish Hitler… offers a satisfyingly ironic, even ‘literary’ explanation for the Holocaust. It seems to close the circle, to account for the unaccountable intensity of the hatred by rooting it in self-hatred.”
Ron Rosenbaum author of ‘Explaining Hitler: The Search for the Origins of His Evil’
In the ideological bedrock of the Third Reich, genealogy was not merely a matter of family history; it was an instrument of survival.
With the Nazi seizure of power in 1933, the production of an ‘Ahnenpass’ (Ancestral Passport) had become a bureaucratic necessity for millions of Germans, a document proving ‘Aryan’ purity and, by extension, the right to operate – and exist – within the new state.
Yet, arguably the most opaque lineage in the entire regime belonged to the new Chancellor himself.
While the machinery of the state demanded biological certainty from its citizens, Adolf Hitler’s own ancestry was marred by a significant documentary void—an illegitimacy in the generation of his father that left the door ajar for political exploitation.
This genealogical gap transformed from a private insecurity into a matter of historical record in 1946.
From a prison cell in Nuremberg, Hans Frank—formerly Hitler’s personal legal counsel and the Governor-General of occupied Poland—penned his posthumous memoir, Im Angesicht des Galgens (In the Face of the Gallows).
Within its pages, Frank detailed a clandestine assignment he claimed to have undertaken in 1930: a quiet investigation into the Führer’s origins, prompted by an alleged blackmail threat from Hitler’s half-nephew.
Frank’s conclusion was explosive.
He postulated that Maria Anna Schicklgruber, Hitler’s paternal grandmother, had been employed in the household of a Jewish family in Graz, the Frankenbergers, and that her illegitimate child was the product of this service.
If validated, this assertion would have categorized Adolf Hitler as a Mischling of the second degree under his own Nuremberg Laws, effectively dismantling the racial logic upon which his authority rested.
This specific allegation has since permeated the historical consciousness, often oscillating between sensationalist conspiracy and uncritical acceptance.
However, to treat Frank’s account as established fact is to misunderstand the evidentiary standards of history.
The durability of the ‘Jewish Hitler’ narrative relies less on archival proof and more on the irony it offers—a convenient psychological explanation for a tragedy that defies rationality.
To properly dissect this claim, we must leave behind the rumour mill of the Reich Chancellery and the Nuremberg cell to apply rigorous scrutiny to the provincial archives of nineteenth-century Austria, where the silence of the record speaks as loudly as the text itself.

The Void In Hitler's Childhood
“I often had the impression that Adolf was at war with his own origins… He never spoke of his family with any affection, only with a dark, brooding silence.”
Hitler’s childhood friend, August Kubizek, from ‘The Young Hitler I Knew’
To understand why the rumor of Jewish ancestry could even take root, one must understand the sheer genealogical fog that surrounded Adolf Hitler’s origins.
He did not come from a lineage of well-documented nobility or established burghers.
He came from the Waldviertel—the ‘Wooded Quarter’ of Lower Austria.
In the 19th century, this was a region of poverty, superstition, and crushing isolation. It was a place of small villages, heavy silences, and rampant inbreeding among the peasant class. In this world, illegitimate births were not just common; they were a fact of life, often resulting from financial barriers to marriage.
Adolf Hitler was born on April 20th 1889, in Braunau am Inn, but the mystery begins half a century earlier.
His father, Alois Hitler, was born in 1837 in the hamlet of Strones, near the Austrian village of Döllersheim.
But Alois was not born ‘Hitler’.
Strones was very small at the time of Alois’s birth and did not even have a church with a baptismal registry.
He was baptised Alois Schicklgruber, the illegitimate son of a 42-year-old peasant woman named Maria Anna Schicklgruber.
On the baptismal register, the space for the father’s name was left blank.
“Illegitimate.”
This single blank space is the crack in the foundation where the myths would later fester. Maria Anna eventually married a man named Johann Georg Hiedler, but for reasons lost to history, Hiedler did not legitimize the boy during his lifetime.
Alois bore the ‘shameful’ name Schicklgruber until he was nearly 40 years old.
It wasn’t until 1876—long after Maria Anna and Johann Georg Hiedler were dead—that Alois, then a climbing customs official who wanted to secure an inheritance from his uncle (Johann Nepomuk Hiedler), went to the parish priest.
With three illiterate witnesses (and perhaps a bit of deception), he had the baptismal registry retroactively altered.
The priest crossed out “Illegitimate” and wrote in Johann Georg Hiedler as the father.
Perhaps due to a clerical error or a desire to standardise the spelling, ‘Hiedler’ became ‘Hitler’.
This bureaucratic sleight-of-hand turned Alois Schicklgruber into Alois Hitler. But socially, the whisper of his illegitimacy remained.
Even Adolf Hitler, in moments of rage, allegedly feared that his father’s unknown past would come back to haunt him.
It was the ultimate insecurity for a man obsessed with blood purity: his own family tree was a ‘Salzburg bottle’—shaken up, murky, and impossible to see clearly through.
It was this void—the missing father of 1837—that Hans Frank would fill with his explosive story in 1946.

The ‘Frankenberger Thesis’ - Hitler’s Jewish Blood?
“The indulgence normally accorded to a man’s origins is out of place in the case of Adolf Hitler, who made documentary proof of Aryan ancestry a matter of life and death for millions of people but himself possessed no such document. He did not know who his grandfather was. Intensive research into his origins, accounts of which have been distorted by propagandist legends and which are in any case confused and murky, has failed so far to produce a clear picture. National Socialist versions skimmed over the facts and emphasised, for example, that the population of the so-called Waldviertel, from which Hitler came, had been “tribally German since the Migration of the Peoples”, or more generally, that Hitler had “absorbed the powerful forces of this German granite landscape into his blood through his father”
Joachim C. Fest, author of ‘Hitler’
The core of the myth of Hitler’s Jewishness lies in what historians call the ‘Frankenberger Thesis’.
The story usually goes like this: In 1930, Hitler received a blackmail letter from his half-nephew, William Patrick Hitler (the son of his half-brother Alois Jr., living in England). William supposedly threatened to expose family secrets unless ‘Uncle Adolf’ set him up with a good job.
According to Hans Frank’s memoirs, Hitler summoned his lawyer and said, “This brat is claiming I have Jewish blood.”
He ordered Frank to investigate the claim confidentially.
Frank claimed he went to Styria in Autria, checked the records, and reported back a devastating finding:
- That in 1836-1837, Hitler’s grandmother, Maria Anna Schicklgruber, was working as a cook for a wealthy Jewish family in Graz named Frankenberger.
- That the family’s 19-year-old son had impregnated the 42-year-old Maria.
- That for years, the Frankenbergers paid alimony to Maria for the child (Alois, Hitler’s father), and that letters were exchanged acknowledging the paternity.
If true, this would make Adolf Hitler one-quarter Jewish.
It is a tantalising narrative.
It fits perfectly with the psychological profile of the ‘self-hating Jew’, a concept popularized in the 1930s by philosopher Theodor Lessing (who was eventually murdered by Nazis).
It suggests that Hitler’s fanatical antisemitism was a projection of his own self-loathing; that he sought externally to destroy the Jew because he sought to destroy the ‘impurity’ within himself.
Likely, the main reason why the story gained traction was because it came from the inside.
Frank was not a gossip columnist; he was the Reichsrechtsführer, the head of Nazi law. If anyone knew where the bodies were buried, it was him.
After the war, the rumour mutated further.
The Soviet NKVD, always eager to humiliate the fascists, promoted the idea.
Historical revisionists picked it up.
Today, it survives in the echo chambers of the internet as a ‘gotcha’ factoid.
It creates a neat, ironic ending to the horror of the Holocaust.
But history is rarely neat, and as we dig into the archives of Graz and the timeline of the 19th century, the Frank story dissolves like sugar in hot water.

The Reality: Why the Jewish Hitler Myth is Impossible
“The legendary Jew from Graz is a product of fantasy… Adolf Hitler’s grandfather was, in all probability, Johann Georg Hiedler.”
Werner Maser, genealogical specialist and author of ‘Hitler: Legend, Myth and Reality’
Let’s be clear: No credible evidence exists to suggest Adolf Hitler had Jewish ancestry.
None.
And it is not just a matter of ‘we can’t find the papers’.
The specific claims made by Hans Frank have been systematically dismantled by historians like Brigitte Hamann, Ian Kershaw, and Richard J. Evans.
The evidence against the myth is overwhelming and geographic.
1. The ‘Jew-Free’ Graz
The most damning piece of evidence against Frank’s story is a boring, bureaucratic fact: Jews were expelled from Styria (including Graz) in the 15th century and were not allowed to return until the 1860s. As historian Brigitte Hamann details in her seminal work ‘Hitler’s Vienna’, there was no Jewish community in Graz in 1837 when Maria Schicklgruber became pregnant. Residence for Jews was strictly illegal. While a few might have visited for short-term trade fairs, no settled Jewish families existed there.
It wasn’t until the fundamental laws of 1867 that Jews were granted the right to settle permanently in Graz again—30 years after Hitler’s father was born. The idea of a wealthy, established Jewish household with a retinue of servants (and a teenage son engaging in illicit affairs) in 1837 Graz is historically impossible.
2. The Non-Existent ‘Frankenberger’
Researchers have scoured the archives of Graz looking for a ‘Frankenberger’. They found no one of that name—Jewish or Christian—living there in the 1830s.
There was a family named Frankenreiter living in Graz at the time, but they were Catholic, not Jewish. Even if one were to stretch the theory and say Frank got the name slightly wrong (Frankenreiter vs. Frankenberger), the dates still don’t match. The Frankenreiter son, Camille, would have been 10 years old when Hitler’s father was conceived—hardly a capable patriarch.
3. Maria Schicklgruber’s Whereabouts
There is no record of Maria Anna Schicklgruber ever working in Graz. She was a peasant woman from the Waldviertel. All documentary evidence places her in and around the village of Strones during this period. The leap that she traveled 200 kilometers south to a city where Jews were banned, found employment in a non-existent household, and then returned to the remote woods to give birth, is a fiction unsupported by a single scrap of paper.
4. The Motivation of Hans Frank
So why did Hans Frank lie?
Ian Kershaw, in his biography Hitler: Hubris, suggests we look at the psychology of the man telling the story. Writing from his death cell, Frank had undergone a conversion to Catholicism. He was terrified of damnation. He hated Hitler by the end, blaming the Führer for leading Germany (and Frank himself) into the abyss.
Kershaw argues that the ‘Jewish Hitler’ story was a way for Frank to demonise Hitler further—to turn the arch-antisemite into a liar and a hypocrite. Alternatively, Frank might have simply believed a rumor he heard, uncritically, because in the chaos of 1946, facts mattered less than moral reckoning.
Or perhaps, Frank fell victim to the same anti-semitic thinking that pervaded the regime: the belief that such monumental evil must somehow be ‘foreign’. To a Nazi like Frank, admitting that a ‘pure’ German could cause such destruction was psychologically impossible. It had to be the result of ‘corrupt blood’.
In a twisted way, claiming Hitler was Jewish was Frank’s way of absolving ‘true’ Germans of ultimate guilt.
5. DNA Evidence (A Modern Postscript)
In 2010, a Belgian journalist and a historian attempted to analyze DNA from relatives of Hitler (specifically from the American branch of the family, descendants of William Patrick). They claimed to find a haplogroup (E1b1b) that is rare in Western Europe but common in North Africa and among Ashkenazi and Sephardic Jews.
Headlines screamed: “Hitler Related to Somalis and Berbers!” or “Hitler Was Jewish!”
However, geneticists quickly urged caution. While the haplogroup is common in Jewish populations, it is also found in Southern Europeans and isn’t a definitive marker of ‘Jewishness’ in a genealogical sense—especially not recent ancestry.
It dates back thousands of years. Finding a genetic marker common in the Mediterranean basin in an Austrian family is not proof of a Jewish grandfather in 1837; it’s just proof of the vast migration of humans over millennia.
It certainly doesn’t validate the specific Frankenberger story.

Conclusion
“Searching for Jewish ancestors in Hitler’s lineage acts as a deflection. It suggests that the destruction of European Jewry was a personal family feud writ large, rather than a systematic, ideological, and state-sponsored genocide.”
Peter Longerich; summary from ‘Hitler: A Biography’
So, was Adolf Hitler Jewish?
The answer – in response to the popular ‘Frankenberger Thesis’ – is an emphatic no.
The man who unleashed the Holocaust was not a ‘secret Jew’.
He was a catholic-born Austrian whose genealogy was typically messy for a region of rural poverty and illegitimacy.
The myth of the Jewish grandfather is not history; it is fake-news folklore. It survives because it is tempting. It offers a kind of poetic justice—a narrative hook that makes the senselessness of the Holocaust feel more like a Greek tragedy.
But as historians like Evans, Kershaw, and Hamann remind us, the truth is far more disturbing. Hitler wasn’t fighting his own blood. He was a man who, through a combination of political opportunism, cultural prejudice, and his own narcissism, propagated a worldview of hate.
He didn’t need a secret Jewish grandfather to become an antisemite. He only needed the toxic atmosphere of early 20th-century Vienna, a shattered post-war Germany, and a willingness to blame ‘the other’ for his own failures.
Accepting the reality—that he was just a man, with no secret lineage, who in large part chose to become a monster—places the burden of history back where it belongs: not on biology, but on human choice.
