Born on December 24, 1905, in Amsterdam, Anna “Ans” van Dijk grew up in a working-class Jewish family. Her early years gave little indication of the notorious figure she would become. Raised in Amsterdam’s vibrant Jewish community, van Dijk experienced a conventional upbringing that instilled in her traditional Jewish values and customs, creating a stark contrast with her later actions during the Nazi occupation.

Before the war, van Dijk married a non-Jewish man named Bram Querido, but their relationship quickly deteriorated. They separated after a short time together, leading van Dijk to establish her own hat shop in Amsterdam. This business venture represented her attempt at independence and self-sufficiency, showcasing her entrepreneurial spirit before the Nazi occupation drastically altered her life’s trajectory.

The German invasion of the Netherlands in May 1940 dramatically changed van Dijk’s circumstances. As Nazi forces occupied the country, Dutch Jews immediately became targets of systematic persecution. Initially, like many Dutch Jews, van Dijk attempted to maintain her normal life while adapting to increasingly restrictive anti-Jewish measures, unaware of the horrific path that lay ahead.

By 1941, the Nazi regime had implemented devastating restrictions on Jewish life in the Netherlands. Jews were forced to register with authorities, barred from public facilities, and required to wear yellow Stars of David. Van Dijk’s hat shop business collapsed under these restrictions, eliminating her source of income and pushing her into increasingly desperate circumstances as survival became her primary concern.

In 1943, the turning point in van Dijk’s life occurred when she was arrested by the Sicherheitsdienst (SD), the Nazi intelligence service. Facing deportation to concentration camps, where almost certain death awaited, van Dijk made the fateful decision that would forever mark her name in history. Rather than face deportation, she agreed to work for the Germans to save herself.

25. Recruitment by SD Officer Willy Lages

The infamous SD officer Willy Lages personally recruited van Dijk as an informant. Lages, already responsible for thousands of Jewish deportations, recognized van Dijk’s potential value as someone who could move within Jewish circles undetected. Their arrangement was simple yet diabolical: she would hunt down Jews in hiding in exchange for her own safety and financial compensation.

24. Creating a False Identity

Operating under the alias “Anneke van Dijk,” she crafted a carefully constructed persona as a member of the resistance. This false identity allowed her to gain the trust of Jews in hiding, presenting herself as someone who could provide assistance, fake documents, or safe houses, when in reality, she was marking them for capture and deportation.

23. Betrayal Methodology

Van Dijk developed a sophisticated methodology for her betrayals. She would approach Jewish people in hiding, claiming to offer resistance services like false identity papers or hiding places. Once she gained their trust and learned their location, she would report this information to her Nazi handlers, who would then organize raids to arrest her victims.

22. The Establishment of a Fake Safe House

In a particularly sinister operation, van Dijk established a fake safe house in Amsterdam. Jews desperately seeking shelter would be directed to this location, believing they had found sanctuary. Instead, they had walked into a trap, with Nazi officers waiting to arrest them. This setup allowed her to betray multiple victims simultaneously with minimal effort.

21. Building a Network of Collaborators

As her operation expanded, van Dijk recruited other Jewish collaborators, creating a network that extended her reach. These individuals, also working to save themselves, helped identify Jews in hiding across Amsterdam and beyond. This network multiplied the devastation she could inflict, making her responsible for betrayals far beyond her personalcapacity.

20. Financial Compensation for Betrayal

For each Jewish person van Dijk betrayed to the Nazis, she received payment, typically between 7.50 and 40 Dutch guilders per victim. This blood money provided her with a comfortable lifestyle during the war, while most Dutch citizens, especially Jews, faced extreme hardship and deprivation. Her financial motivation became a key element in her postwar trial and public condemnation.

19. Personal Relationship with Miep Zagon

While a collaborator, van Dijk formed a romantic relationship with Miep Zagon, a Jewish woman. This relationship added another layer of complexity to van Dijk’s character, as she continued betraying Jews while maintaining an intimate relationship with a Jewish partner. She even obtained false papers for Zagon, protecting her while sending others to their deaths.

18. The Scale of Her Betrayal

Over the course of her collaboration, van Dijk is believed to have been responsible for the betrayal of between 100 and 200 Jews. Each of these individuals was subsequently deported to concentration camps, where many perished in the Holocaust. The scale of her betrayal made her one of the most prolific collaborators in the occupied Netherlands.

17. Survival Through Betrayal

Throughout the Nazi occupation, van Dijk’s strategy of collaboration succeeded in its primary goal: her own survival. While thousands of Dutch Jews were being transported to death camps, she maintained a relatively comfortable existence protected by her SD employers. Her case became a stark example of survival through complicity and moral compromise.

16. Liberation and Initial Escape

When the Netherlands was liberated in May 1945, many collaborators were immediately arrested in the wave of retribution that followed. Van Dijk, however, initially evaded capture. She fled to The Hague under yet another false identity, attempting to blend into post-war Dutch society and escape accountability for her wartime activities.

Van Dijk’s freedom after the war was short-lived. On June 20, 1945, she was arrested by Dutch authorities in The Hague. Her capture came when people she had betrayed who survived the camps recognized and reported her. The net had finally closed on one of the most notorious collaborators in Dutch history.

14. Comprehensive Investigation

After her arrest, Dutch authorities extensively investigated van Dijk’s collaboration activities. Survivors came forward with testimonies, and Nazi documents provided evidence of her work for the SD. Investigators painstakingly reconstructed her network and methods, building what would become an overwhelming case against her in court.

13. Trial for High Treason

In 1947, van Dijk stood trial for high treason against the Netherlands and crimes against humanity. Her trial attracted significant attention as it represented one of the most egregious cases of Jewish collaboration with the Nazis. The prosecution presented evidence of dozens of specific betrayals, each constituting a separate charge against her.

12. Defense Based on Coercion

During her trial, van Dijk’s defense rested primarily on the claim that she acted under duress, arguing that her initial cooperation with the Nazis came from fear for her own life. However, the evidence of her continued betrayals, recruitment of others, and financial compensation undermined this defense, suggesting a level of willing participation transcending mere survival.

11. Confession of Guilt

Facing overwhelming evidence, van Dijk ultimately confessed to her crimes during the trial proceedings. Her confession detailed specific betrayals and acknowledged her role in sending fellow Jews to concentration camps. This admission removed any remaining doubt about her culpability, though it did little to explain her moral transformation from community member to betrayer.

10. Death Sentence Imposed

On February 24, 1947, the Special Court in Amsterdam sentenced Ans van Dijk to death for her crimes. The severity of the sentence reflected the exceptional nature of her betrayal and the number of victims attributed to her actions. She became the only Dutch woman condemned to death for wartime collaboration whose sentence was carried out.

9. Failed Appeals for Clemency

Following her sentencing, van Dijk pursued multiple appeals for clemency. Her legal team petitioned Queen Wilhelmina for a pardon, emphasizing van Dijk’s own Jewish identity and the impossible circumstances of the occupation. These appeals were systematically rejected, with authorities determining that the magnitude of her crimes warranted the maximum punishment.

8. Religious Conversion Before Execution

In the months between her sentencing and execution, van Dijk underwent a religious conversion to Catholicism. This spiritual shift occurred while working with prison chaplains, suggesting a possible attempt to find forgiveness or redemption in her final days. This conversion added yet another complex dimension to her already contradictory identity.

7. Execution by Firing Squad

On January 14, 1948, Ans van Dijk was executed by firing squad at Fort Bijlmer near Amsterdam. She became the only woman executed for war crimes in the Netherlands after World War II. Her execution represented the Dutch justice system’s determination to punish the most egregious acts of collaboration, regardless of the perpetrator’s gender or background.

6. Posthumous Controversy

Even after her death, van Dijk’s case remained controversial in Dutch society. Some viewed her execution as appropriate justice for her betrayals, while others questioned whether she had been judged more harshly because she was a woman or because she was Jewish. Her case prompted difficult questions about justice, collaboration, and moral choice during the occupation.

5. Historical Documentation

Van Dijk’s case has been extensively documented in Dutch historical archives. Court records, witness testimonies, and Nazi documents provide a comprehensive record of her activities, making her one of the most thoroughly documented collaborators of the war period. This extensive documentation has allowed historians to study her case as an example of the complex moral compromises made during the occupation.

The story of Ans van Dijk became embedded in Dutch cultural memory as a cautionary tale about the moral compromises of occupation. Her case has been referenced in Dutch literature, historical studies, and discussions about national memory of the war period. She represents a difficult aspect of Dutch wartime history that challenges simplistic narratives of resistance and collaboration.

3. The Anne Frank Connection Theories

In recent years, some researchers have suggested van Dijk may have been connected to the betrayal of Anne Frank and her family, who were discovered in their secret annex in August 1944. While no definitive evidence directly links van Dijk to this specific betrayal, her methods and timeframe of operation have led some historians to consider her as a possible informant in this infamous case.

2. Legacy of Moral Complexity

The case of Ans van Dijk forces confrontation with uncomfortable questions about human behavior under extreme pressure. Her transformation from ordinary Jewish citizen to Nazi collaborator illustrates the moral gray areas created by systematic persecution and the complex decisions individuals made for survival. Historians continue to analyze her case as an example of the impossible choices faced during the Holocaust.

Ultimately, Ans van Dijk has become a symbol of the most painful moral compromises forced by the Holocaust. Her story demonstrates how the Nazi system didn’t just murder Jews but corrupted human relationships and moral boundaries. As one of history’s most notorious collaborators, she represents the Holocaust’s devastation not just of Jewish lives but of Jewish community bonds and ethical foundations.
