Overview

This episode delves into Anthony Easton's decade-long investigation into his family's mysterious past and the disappearance of their multi-billion pound fortune in Germany. Triggered by the death of his enigmatic father, Anthony uncovers a legacy marked by loss, survival, and the theft of assets during the Nazi era. Central to the episode is the discovery of a "double identity" in his father's birth certificate, and how the Eisner family—once wealthy Jewish industrialists in Berlin—navigated the terror and bureaucracy of Nazi Germany. The episode builds toward the puzzle of Martin Hartig, a key but shadowy figure who may have shaped the family's fate during the Aryanization of Jewish property.

1. Uncovering Family Secrets

• Anthony’s Discovery: After his father's death, Anthony Easton sorts through family possessions, finding German money, old family trees, and cryptic notes.
  • “Like with the suitcase, it was like a kind of heart fluttering thing. It's like looking in someone else's diary. ...big people, big characters doing interesting, important things and then they're reduced to nothing.”
    — Anthony Easton [01:15]

    — Peter Eisner (read aloud) [04:04]

3. Navigating Nazi Oppression

• Proximity to Power: The Eisner home was mere blocks from Nazi Party headquarters, exposing the family to rallies and book burnings. [04:49]
• Family Survival Tactics: Rudolf Eisner, Anthony’s grandfather, leveraged his engineering expertise to build the subframe for Hitler’s prized Mercedes Formula One car—the “Silver Arrow.”

4. Aryanization & Asset Theft

• Legalized Plunder: David De Jong explains how Nazis used "Aryanization" to strip Jews of assets under the guise of legality.

    — Anthony Easton [12:18]
• His Role: Hartig, an economist and “Troyhander” (trustee), may have helped the Eisners navigate Aryanization laws. But his motives remain unclear.
  • “People who do major things within family groups get remembered. So why was Martin Hartig not remembered? Who was this guy who turned up?”
    — Anthony Easton [13:24]

[Narrator / Charlie Northcote]

Anthony Easton has spent over a decade investigating the mysteries of his family and the disappearance of their multi billion pound fortune in Germany. Among the many records he found as he dug through his dad's stuff in the UK after he died was a leather bound book, a photo album filled with unfamiliar faces, black and white images from the 1920s and 30s. A window into a past which he knew nothing about.

[Anthony Easton]

Like with the suitcase, it was like a kind of heart fluttering thing. It's like looking in someone else's diary. You know you're not really meant to be there. There's something very personal about it that it's not to do with you. There are summer holidays, winter holidays, skiing at the beach, my dad as an infant being pushed in a pram outside the house in Berlin. When you look at those pictures and you think about what lives those people were going to go through, those children going to go through, those are very, very haunting pictures. They are big family, they are big people, big characters doing interesting, important things and then they're reduced to nothing.

[Narrator / Charlie Northcote]

From Radio 4 and the History podcast. This is the house at number 48. I'm Charlie Northcote. Episode 4 the Silver Arrow.

[Anthony Easton]

This is where my dad grew up.

[Narrator / Charlie Northcote]

No way.

[Anthony Easton]

Yeah. So I've got some pictures we can look at. Here's a picture of dad from March 1927 in a very bonnie bonnet with his nanny.

[Narrator / Charlie Northcote]

He's got a teddy bear in his.

[Anthony Easton]

Hand, with a teddy bear in his hand and white booties and socks. And you can see here, that's the railings. Exactly the railings at the front and, and the building itself.

[Narrator / Charlie Northcote]

Using Anthony's dad's photo album, we've retraced his steps back to the house where he was raised. In his home was a beautiful white villa on Gentine Strasse in Berlin with green vines growing up the facade. Inside, the banisters had a Greek goddess carved on every railing. There were bustling staff quarters downstairs with a cook, a maid and a nanny. And upstairs, Peter and his sister had a room full of toys. A wooden windmill, a stuffed elephant, their dog, a miniature Poodle called Carrot is scuttling at the heels of their parents. Among these photos, neatly folded in an envelope, Anthony also found notes written by his dad reflecting back on when he was 11 years old. They're a window into the life of a young Jewish boy living in the heart of of Nazi Germany.

[Anthony's Father (Peter Eisner)]

My boy's school, just a minute walk away in a large purpose built red brick building was a state run establishment. There were two other Jewish boys in my class. Worst of all was our professor. An elderly and typical Prussian with dueling scars and a war veteran. He regularly harangued us, alternately denigrating the Treaty of Versailles and of course the Jews. Sometimes he had the decency to ask the three of us to leave the classroom before he started. This was my introduction to the new Germany.

[Narrator / Charlie Northcote]

Nazi party headquarters were situated just blocks away from the Eisner family home. Outside their windows they would have heard the torchlit rallies, the singing, the burning of books. After the passing of the Nuremberg race laws in 1935, Germany became a dangerous place to be Jewish. If Antony's grandfather Rudolf Eisner was going to save his family, to save their business, he needed a plan. And the one he came up with was incredibly Clever. Putting his PhD in engineering to the test, he helped make a special gift for Adolf Hitler himself. Something he hoped would make him indispensable to the Chancellor.

[Anthony Easton]

There was a sort of system by which important Jewish families or Jewish families who were doing important things for the German state were more protected. Rudolf was a really top metallurgist. He built the subframe for the Mercedes Formula One car, Hitler's 1937 Silver Arrow. It was Hitler's pet project and it projected German technological brilliance onto the world stage.

[Narrator / Charlie Northcote]

The Silver Arrow was the fastest racing car in the world, reaching speeds of more than 200 miles an hour.

[Anthony Easton]

In the middle of that Nazi car was a Jewish engineer and a Jewish metallurgist. And I think that probably protected him.

[Narrator / Charlie Northcote]

Rudolf's strategy for protecting his family seemed to work for a time. But everywhere around them there were reminders that there were wolves on the streets. Men in brown shirts boiling with rage and resentment. His 11 year old son Anthony's dad saw them whenever he left the house.

[Anthony's Father (Peter Eisner)]

It was a quiet Sunday. I'd walked the short distance from my parents home past the local pub. A small group of rough looking, poorly uniformed SA stormtroopers were posturing outside the entrance. When an elderly man emerged. He was jeered by these rowdy SA men and when he tried to ignore them, they started to jostle him, he was pushed over and fell to the ground, whereupon he was given a few hard kicks by the jack booted Stormtroopers. When I returned home, I decided not to mention the incident to my parents as I was afraid they might stop me from going out on my own. It was easier to shut your eyes to things. There was no justice system.

[Narrator / Charlie Northcote]

One of the strangest paradoxes of Nazi Germany was the juxtaposition of violence and mind numbing bureaucracy. At the same time Stormtroopers were beating up Jews on the streets, men in suits were creating a spider web of laws designed to suffocate Jewish owned businesses. Jews were banned from being tax advisers, lawyers or sitting on the boards of companies. And as the head of a huge corporation, every single one of those laws would have impacted Rudolf Eisner. Author David De Jong is an expert on how Nazis targeted Jewish assets.

[David De Jong (Author / Expert)]

As persecution ramps up over the 1930s, this very perversely cynical term of Aryanization takes root. Now Aryanization denotes the removal of any aspect of Jewish ownership from an asset, whether that is real estate, business shares, bonds, jewelry, art, land, you name it, anything of relative value. This practice of Aryanization had initially a veneer of a legal transaction.

[Narrator / Charlie Northcote]

In notes belonging to his grandfather, Anthony has found clues about the intense pressure faced by his family. Jewish businesses that had existed for decades were being forcibly taken over and people were disappearing.

[Anthony Easton]

His diaries are just lists of people's names who came to see him every day. Ten names a day, all German Jews and I would think every single one of them, their lives have been shut down and their businesses stolen. You know, members of his family, people who are on the board of Hanjiwerke were arrested. The more I read about it, the harder I imagine it must have been for Rudolph and my grandmother to see what was going on and to be hemmed in on every side. And you know, it's one little thing after another. And all of those things are like building a cage around you until you're trapped.

[Narrator / Charlie Northcote]

For a lot of people, fleeing was simply not an option. By 1937, any Jewish family who decided to leave Germany was forced to surrender 92% of their wealth to the state.

[David De Jong (Author / Expert)]

They had to pay a so called Reich flight tax, Reich Flechsteuer, which meant that they had to pay the Nazi regime in order to immigrate. So they would sell their assets at a fire sale price in order to raise money for their escape. It's incredibly personal. It's also incredibly painful because now you are left with little to nothing.

[Narrator / Charlie Northcote]

Do the Eisner's flee and lose over 90% of what they own. Or do they stay and risk their lives? Until Anthony began piecing together his family story, his sister Nicola had no idea her father and grandparents went through this ordeal. Who's going to help you? Where are you going to go? Maybe you sort of hope that things aren't going to get as bad as they get because you've got so much to lose. It will be terrifying. At the height of this impossible dilemma, a mysterious man enters the lives of the Eisner family. His name is peppered throughout a guestbook preserved by Anthony's father from their country estate just outside of Berlin.

[Anthony Easton]

Here's the Martin Hartig 21st to 22nd of August 1937. And then another one right beneath it.

[Narrator / Charlie Northcote]

My warmest thanks for the continued friendship and welcome with swimming, cycling and walking. It feels wonderful to see you again.

[Anthony Easton]

Look at these three. All of this page is Martin Hartig.

[Narrator / Charlie Northcote]

Why was this man, Martin Hartig visiting the Eisner family in their quiet country estate so often at the height of this crisis?

[Anthony Easton]

When I started this journey, I knew nothing of Martin Hartig. He'd never ever been mentioned. So it was extraordinary because I could see that this man was all over the lives of my grandparents.

[Narrator / Charlie Northcote]

In documents in Germany's archives, Anthony found a clue. Martin Hartig is described as an economist and a tax advisor and he may have played an important role in helping the Eisner family navigate Aryanization laws under the Nazis.

[Anthony Easton]

Martin Hartig was what was known as a Troy hander and that translates simply as a trustee, someone you can rely on, a trusted person.

[Narrator / Charlie Northcote]

In the face of catastrophe. Martin Hartig must have felt like a savior. As the net was closing in on the Eisner family and their incredible properties in Berlin, they had a skilled economist helping them navigate the Nazi storm. But it all sounds a bit too good to be true.

[Anthony Easton]

You know, that's where I started to think about him. Why had I not heard of him? People who do major things within family groups get remembered. So why was Martin Hartig not remembered? Who was this guy who turned up?

[Narrator / Charlie Northcote]

Next time on the house at number 48. Is Martin Hartig a guardian angel or is he an enemy from within?

[David De Jong (Author / Expert)]

For the loving hospitality.

[Narrator / Charlie Northcote]

Many thanks again for the beautiful time.

[David De Jong (Author / Expert)]

Here.
