Dutch Nazi Traitor Who Killed His Own People – Painful End of Hermannus Reydon

Dutch Nazi Traitor Who Killed His Own People - Painful End of Hermannus Reydon

Fetched image 1

Eight days after Hermannus Reydon was given power over the cultural life of an occupied nation, he returned to his house in Voorschoten and stepped through the front door.

Someone was waiting inside.

The man did not wear a military uniform. He carried no official badge, no polished boots, no papers stamped with the German eagle.

He looked like the kind of person Reydon’s propaganda rarely noticed: quiet, educated, ordinary enough to disappear in a crowd.

For one suspended moment, the two men stood within a few feet of each other.

Reydon had spent years teaching the Dutch people that power belonged to those bold enough to seize it. He had praised obedience, mocked democracy, and helped create a world in which a government could decide who was allowed to speak, paint, perform, publish, work, or even belong.

Now the balance of power inside his own home had changed.

The stranger raised a pistol.

To understand how Hermannus Reydon arrived at that doorway, you have to return to the first days of May 1940—when Dutch skies filled with German aircraft and the future of the Netherlands collapsed in less than a week.

On May 3, before the invasion had even begun, the Dutch government arrested Reydon.

Officials considered him one of the most dangerous men in the country.

That description may have sounded strange to anyone who saw him from a distance. Reydon was not a general. He commanded no tanks. He had never led an army across a border.

He was a lawyer by education and a journalist by profession.

His weapons were sentences.

Born in Voorschoten in 1896, Reydon studied law at Utrecht. He possessed the education, vocabulary, and professional standing that might have allowed him to defend institutions, protect citizens, or challenge abuses of power.

Instead, he turned those advantages against democracy.

In 1932, he became one of the earliest members of the Nationaal-Socialistische Beweging, the Dutch National Socialist Movement known as the NSB. His membership number was 252—a sign that he had joined before opportunists began gathering around the movement in search of jobs and influence.

Reydon did not stumble into fascism after the Germans arrived.

He chose it years before.

He edited Volk en Vaderland, the NSB’s weekly newspaper, and later worked for Het Nationale Dagblad. Week after week, his movement’s publications repeated the same poisonous ideas: democracy was weak, political disagreement was decadence, the nation needed discipline, and certain people could never truly belong.

The articles did not drag anyone from bed in the middle of the night.

Not at first.

They did something more patient.

They taught readers which neighbors to distrust.

They made contempt sound intellectual. They dressed prejudice in theories about blood, soil, destiny, and national renewal. They turned cruelty into policy language and exclusion into something that could be discussed calmly over breakfast.

Reydon understood a principle every extremist movement eventually discovers: before a government can persecute a group of people, it must persuade the public to see those people as a problem.

That work begins with words.

By the late 1930s, Europe was sliding toward catastrophe. Hitler had destroyed German democracy, imprisoned opponents, stripped Jews of their rights, and built a regime around racial hatred and conquest.

Yet Reydon continued to defend the ideology.

Fetched image 3He described parliamentary democracy as foreign to the nature of the Dutch people. He glorified a mythical Germanic community bound to land and ancestry. He spoke of society as if human beings were crops to be sorted—healthy from diseased, useful from unwanted.

Educated men listened.

Party members distributed his newspapers.

Ordinary people saw the slogans at train stations, on street corners, and outside factories.

Some laughed at the NSB. Others argued with its members. Many assumed the movement would never gain real power in the Netherlands.

That assumption lasted until the morning of May 10, 1940.

German forces crossed the border before dawn.

Aircraft thundered overhead. Paratroopers descended near strategic bridges and airfields. Dutch soldiers fought desperately, but the attack came with a speed designed to paralyze resistance.

Four days later, German bombers struck Rotterdam.

The city center burned. Streets disappeared beneath smoke and shattered masonry. Civilians stumbled through wreckage carrying children, blankets, suitcases, or nothing at all.

The threat of further destruction forced the Dutch military to capitulate.

The government fled. Queen Wilhelmina went into exile. German officials entered ministries, police headquarters, radio stations, newspaper offices, and municipal buildings.

And on May 15, the prison door holding Hermannus Reydon opened.

The man the Dutch government had identified as a danger to the state walked free because the danger had conquered the state.

He returned not as a humbled prisoner but as a collaborator whose beliefs now matched those of the occupiers.

Around him, Rotterdam was still smoking.

Across the Netherlands, families were trying to discover who had survived the bombing. Soldiers were returning home after defeat. Civil servants faced new commanders. Newspaper editors waited for instructions from men who had entered their country by force.

For Reydon, occupation was not a national tragedy.

It was an opportunity.

The German authorities needed Dutch collaborators who understood the language, institutions, and habits of the population. They needed local faces who could make foreign domination appear like national renewal.

Reydon was ready.

He resumed his work in the NSB’s propaganda network and remained closely involved in political education. His writing no longer represented a frustrated movement operating at the edges of society.

It now stood behind the authority of an occupation regime.

The change did not happen all at once.

That was part of its effectiveness.

A newspaper received a warning.

An editor discovered that certain subjects could no longer be discussed.

A Jewish civil servant was dismissed.

A teacher was ordered to complete a form.

A musician was told that continued employment required registration.

A bookstore owner learned which titles could remain in the window.

Each action looked administrative when viewed alone. Together, they formed a cage.

The German occupation authorities wanted control of more than police stations and railways. They wanted control over the Dutch imagination.

Fetched image 2News had to confirm the occupiers’ version of reality. Radio had to carry approved voices. Film audiences had to watch German newsreels before the main feature. Artists, writers, actors, musicians, photographers, filmmakers, journalists, and booksellers were brought under a system designed to regulate cultural life.

In November 1941, the occupiers established the Nederlandsche Kultuurkamer—the Dutch Chamber of Culture.

Membership became compulsory for people who wanted to continue working in many creative professions. Those who refused could lose the legal right to practice their craft. Applicants were questioned about their ancestry, and Jewish artists were excluded.

A violinist’s career could end because of a racial declaration.

An author’s manuscript could become illegal without a single sentence being changed.

A painter could still possess his hands, his eyes, and his talent, yet be forbidden to call himself a professional.

The system did not simply censor art.

It transformed culture into a privilege granted by the regime.

Reydon was not the only architect of this machinery, and he did not personally design every decree. But he served it willingly. He spent years helping the NSB create the ideological atmosphere in which such measures could be presented as necessary, orderly, and patriotic.

That distinction matters.

Mass persecution rarely begins with the appearance of the final destination.

It begins with definitions.

Who is a citizen?

Who is loyal?

Who is dangerous?

Who may work?

Who may teach?

Who may appear on a stage?

Who may be printed in a newspaper?

Who must be registered?

Who must be removed?

The language becomes colder as the consequences become more brutal.

Jewish citizens were pushed out of public life. Their businesses were marked and seized. Their movements were restricted. Children were removed from schools. Families were forced to wear the yellow star.

Then came the arrests.

At night, doors opened under police fists.

Names were checked against lists.

Men, women, children, grandparents, infants, doctors, tailors, teachers, musicians, mechanics, and shopkeepers were taken from homes they had occupied for years.

Some neighbors watched from behind curtains.

Some tried to help.

Some told themselves there was nothing they could do.

Others had already absorbed enough propaganda to believe that the people being taken away had somehow caused the disaster descending upon them.

That was the victory of men like Reydon.

Not that every citizen became a fanatic, but that enough people became confused, intimidated, indifferent, or silent.

The deportation trains did not depart from newspaper offices. The gas chambers were not hidden behind printing presses.

But the road to those trains had been cleared by years of language designed to separate human beings into categories of value.

By the end of the Holocaust, approximately 107,000 Jews had been deported from the Netherlands. Roughly 102,000 were murdered.

Those numbers are so enormous that the mind tries to turn them into statistics.

But every number once had a voice.

Every number had a name someone called from another room.

Every number had a coat hanging by a door, a chair at a table, a favorite song, a private fear, a person who expected them to come home.

In Reydon’s newspapers, people could be reduced to labels.

On the railway platforms, those labels became families holding one another beneath armed guard.

Still, Reydon climbed.

The occupation rewarded loyalty. Men who had been mocked before the war entered offices previously closed to them. Small ideologues acquired large titles. Collaborators learned how quickly arrogance grows when backed by uniforms, files, and prisons.

Reydon became increasingly involved in the ideological education of the NSB and in organizations built around the movement’s vision of blood, agriculture, and national community.

He was not known for theatrical charm.

He offered something more useful to the regime: conviction.

He believed.

That made him valuable.

An opportunist may change sides when the wind shifts. A fanatic will keep working while cities burn, neighbors disappear, and the evidence of evil becomes impossible to ignore.

By the winter of 1942, the Netherlands had been occupied for more than two and a half years.

Food was becoming scarcer. Fear had become routine. Illegal newspapers moved secretly from hand to hand. Resistance groups forged documents, hid Jewish families, sabotaged communications, stole ration cards, and targeted collaborators.

The Germans answered resistance with arrests, torture, executions, and collective punishment.

Public life divided into layers.

There was the official Netherlands of approved newspapers, staged ceremonies, Nazi banners, controlled radio broadcasts, and bureaucratic announcements.

Beneath it lived another Netherlands.

In attics, barns, cellars, hospitals, workshops, churches, universities, and back rooms, people lied to the authorities so that others might live.

A printer risked execution for producing a forbidden page.

A civil servant altered a record.

A farmer hid strangers beneath his roof.

A student carried false identification papers inside her coat.

A doctor treated someone whose existence had been erased from official life.

The struggle was no longer only over territory.

It was over reality itself.

On January 28, 1943, Tobie Goedewaagen resigned as Secretary-General of the Department of Public Information and the Arts after conflicts within the Nazi collaborationist leadership.

Hermannus Reydon was chosen to replace him.

On February 1, he took office.

He also became president of the Dutch Chamber of Culture.

The lawyer who had rejected democracy now stood near the top of a structure capable of deciding which ideas could circulate and which artists could work. He had moved from party journalism to institutional power.

For years, he had argued that culture should serve ideology.

Now he had the authority to enforce that belief.

Inside government offices in The Hague, his appointment was another administrative change. A name disappeared from a door; another replaced it. Files were transferred. Subordinates adjusted themselves to a new superior.

But beyond those offices, people understood what the appointment meant.

Reydon was no moderate bureaucrat reluctantly carrying out German orders.

He was one of the earliest Dutch believers in National Socialism.

He had spent a decade preparing for this moment.

The regime had placed a committed propagandist in charge of the machinery that shaped public information and cultural life.

It appeared that Reydon had won.

He had survived arrest, invasion, political rivalry, and the collapse of the country he despised. His enemies were underground, imprisoned, exiled, or dead. His newspapers could circulate openly while resistance publications were printed in secret.

He had offices, titles, influence, and the protection of the occupation.

But while Reydon was moving upward, another educated Dutchman had been moving in the opposite direction.

His name was Gerrit Willem Kastein.

He, too, had studied at a university.

He, too, understood the power of disciplined thought.

But where Reydon used education to build arguments for exclusion, Kastein had trained to heal the human nervous system.

He was a neurologist.

Before the invasion, Kastein had studied medicine in Groningen, continued his education in Germany, and completed his doctoral work in the Netherlands. He had seen political extremism spreading across Europe and had become active in radical left-wing politics. He helped endangered people cross borders and served with an ambulance during the Spanish Civil War.

When the Germans occupied the Netherlands, Dr. Kastein did not accept the new order.

He joined the resistance.

Eventually, he became a leader of CS-6, a clandestine group named after an address in Amsterdam. Its members believed that certain collaborators were not merely expressing opinions; they were actively strengthening a system that arrested and killed people.

The group forged documents, gathered intelligence, conducted sabotage, and planned attacks.

Kastein’s medical training had taught him to remain calm under pressure.

People who knew of his resistance work described a man capable of frightening composure.

While Reydon’s name appeared in official publications, Kastein moved through a world without official recognition. He could not announce his work. He could not defend his choices in a newspaper. Every meeting carried the possibility of betrayal.

The doctor and the propagandist were approaching each other long before either man entered that house.

One believed the individual existed to serve an authoritarian state.

The other had decided that resisting that state required personal action, even at the risk of his life.

In early February 1943, CS-6 struck Lieutenant General Hendrik Seyffardt, a prominent Dutch collaborator associated with recruiting volunteers for the German war effort.

Then the group turned toward Reydon.

Only six days had passed since his appointment as Secretary-General.

He had barely settled into the office.

On February 7, Kastein went to Reydon’s home on the Leidseweg in Voorschoten.

What happened inside was violent, fast, and morally darker than the clean endings people often prefer when remembering resistance.

Reydon’s wife, Wilhelmina Angenita Haak Steenhart, was shot and killed.

Kastein remained inside.

Then Reydon came home.

The man who had entered public life through words found a stranger waiting in the private space where he expected safety.

Perhaps Reydon first saw the pistol.

Perhaps he looked at the man holding it and understood immediately why he had come.

No surviving record can preserve every movement of his face. But the reversal itself is unmistakable.

For years, Reydon had written about strength as if it belonged naturally to men like him. He had supported a regime that entered homes, separated families, and reduced human beings to entries on lists.

Now his own doorway had become a place of judgment.

There were no subordinates beside him.

No editorial board.

No party crowd.

No German official placing a reassuring hand on his shoulder.

Only the doctor, the weapon, and the sudden recognition that official power could not protect him from every consequence.

The shots struck Reydon.

But they did not kill him immediately.

He survived.

For more than six months, the man who had imagined himself shaping the future of Dutch culture remained alive with his wounds.

His formal titles continued for a time, but his power had already vanished. Others took over the work. The bureaucracy kept moving without him, as bureaucracies under dictatorships always do.

A system that teaches people they are instruments eventually treats even its most loyal servants as replaceable.

Reydon had believed that he was helping create history.

Now history continued while he lay incapacitated.

Kastein did not live to see Reydon’s death.

Twelve days after the attack, on February 19, German security forces arrested him in Delft. He was taken to the Binnenhof in The Hague for interrogation.

The resistance doctor knew what capture meant.

Names would be demanded.

Addresses would be demanded.

Every friendship could become a death sentence. Every moment of weakness could send German officers toward another hidden room.

During his detention, Kastein threw himself through a window.

He was taken to a hospital and died that day.

He was thirty-two years old.

His death protected secrets that torture might have exposed, but it did not stop the machinery of retaliation.

The Nazis responded to attacks on collaborators with collective vengeance. Under the policy associated with Operation Silbertanne, death squads murdered Dutch civilians and opponents in reprisal.

More than fifty people were killed in these retaliatory assassinations.

That is the part of the story that refuses to become simple.

Resistance was necessary, but resistance operated in a landscape deliberately poisoned by the occupiers. A bullet aimed at a collaborator could bring bullets into the homes of innocent people. The regime ensured that every act of defiance carried consequences beyond the original target.

Violence spread outward.

Wilhelmina Reydon was dead.

Kastein was dead.

Unrelated Dutch citizens were murdered in reprisal.

And throughout it all, the deportation trains continued to move east.

On August 24, 1943, Hermannus Reydon finally died from the wounds he had suffered in February.

The occupation authorities gave him the ceremony reserved for a loyal servant.

His body was displayed in The Hague. High-ranking Nazis and NSB officials attended the funeral proceedings. Anton Mussert was there. Arthur Seyss-Inquart, the Reich Commissioner who governed the occupied Netherlands, was there. Representatives of the machinery Reydon had served gathered to honor him.

There were uniforms, speeches, salutes, and carefully arranged symbols.

The regime attempted to turn his death into propaganda.

But ceremonies cannot control the final meaning of a life.

They can only try.

Reydon’s coffin was transported for burial in Lunteren, a place closely associated with the NSB’s mass gatherings. His supporters could surround him with flags and describe him as a loyal patriot.

History would use different words.

Collaborator.

Propagandist.

National Socialist.

A man who used education not to protect the public from lies, but to make lies more respectable.

He did not personally drive every train from Westerbork.

He did not personally arrest every Jewish child.

He did not personally operate a gas chamber at Auschwitz or Sobibor.

That is precisely why his story matters.

The greatest crimes in history are never committed only by the people who pull triggers, guard camps, or open gas valves.

They require professionals.

Lawyers who redefine rights.

Civil servants who organize lists.

Editors who repeat approved language.

Teachers who normalize hatred.

Artists who glorify power.

Business leaders who choose profit over conscience.

Intellectuals who build elegant explanations for cruelty.

Propagandists who make persecution sound like public safety.

Reydon’s hands did not need to touch every victim for his work to serve the system that destroyed them.

He helped prepare the moral atmosphere.

He helped create the vocabulary.

He helped turn neighbors into categories and categories into targets.

That is how words become weapons.

Not because ink can physically break down a door, but because repeated lies can persuade enough people not to object when the door is broken down.

Not because a newspaper can build a concentration camp, but because propaganda can teach a society to look away as human beings are sent there.

The Netherlands had a long democratic tradition, an educated population, respected institutions, newspapers, universities, courts, churches, artists, and civil servants.

None of those things made it immune.

The collapse did not require every Dutch citizen to become a Nazi.

It required only that committed extremists gain power, that enough professionals cooperate, that fear silence enough witnesses, and that persecution proceed one administrative step at a time.

First, the language changed.

Then the rules changed.

Then the uniforms appeared at the door.

Today, the technology is different.

Propaganda no longer needs a printing press, a government radio station, or a uniformed official standing beside a newspaper editor.

A lie can cross a country in seconds.

An invented accusation can reach millions before the truth reaches a hundred.

Algorithms can reward outrage. Anonymous accounts can manufacture crowds. Edited videos can transform victims into villains. Repetition can make absurdity feel familiar, and familiarity can be mistaken for truth.

The people spreading hatred may describe themselves as commentators, patriots, influencers, intellectuals, or defenders of order.

The labels change.

The method does not.

Find a group to blame.

Reduce its members to a single identity.

Repeat the most frightening examples.

Mock anyone who asks for evidence.

Call compassion weakness.

Call censorship protection.

Call exclusion unity.

Call cruelty necessary.

Then wait for ordinary people to become accustomed to the language.

Hermannus Reydon’s life is not only a story about one Dutch collaborator who died in 1943.

It is a warning about what happens when educated people surrender conscience to ideology.

Intelligence does not make a person moral.

A degree does not prevent fanaticism.

Professional language does not make an argument humane.

Sometimes education merely gives hatred better grammar.

Reydon had every opportunity to recognize what his beliefs were producing. He lived through invasion, occupation, repression, exclusion, and deportation. He saw the movement he supported acquire real power.

He did not turn away.

He stepped closer.

That was his defining choice.

And choices, repeated often enough, become character.

The quiet doctor who waited inside Reydon’s home also made choices. Some saved lives. Others brought death. His story carries courage, desperation, sacrifice, and the terrible moral burden of resistance under occupation.

History should not polish such events until every edge disappears.

But neither should it pretend neutrality between those who built persecution and those who risked themselves to oppose it.

Reydon wanted a nation in which the state controlled culture, truth, and belonging.

He briefly achieved the power he had sought.

Six days later, he walked through his front door and discovered how fragile borrowed power could be.

His newspapers could command obedience.

His office could silence artists.

His allies could imprison opponents.

But none of them could erase the consequences of the ideas he had chosen to serve.

The final lesson is larger than his death.

Truth is not self-defending.

Democracy is not self-repairing.

Human dignity does not survive merely because decent people privately believe in it.

Each must be defended publicly—by editors who refuse the convenient lie, by lawyers who protect rights when protection is unpopular, by artists who will not turn their talent into obedience, by citizens who recognize that the persecution of a neighbor is never someone else’s problem.

The darkest chapters of history were not written only by monsters.

They were edited, approved, stamped, distributed, and explained by respectable people who decided that career, ideology, or belonging mattered more than truth.

And whenever educated men begin teaching a nation whom it is permitted to hate, history is already standing at the door.

*Historical basis: Reydon was an early NSB member, editor of its publications, an opponent of democracy, and was interned from May 3 to May 15, 1940. He became Secretary-General of the Department of Public Information and the Arts and president of the Kultuurkamer on February 1, 1943. CS-6 attacked his home on February 7; his wife was killed, and Reydon died from his wounds on August 24, 1943. The Kultuurkamer required cultural professionals to register, barred those who refused from practicing, and helped place Dutch cultural life under National Socialist control. Approximately 107,000 Jews were deported from the Netherlands, and roughly 102,000 were murdered. *
