The Fake Hitler Diaries That Fooled the Experts

The Fake Hitler Diaries That Fooled the Experts

A huge scoop, millions of dollars, a world-famous historian, and a forgery so clumsy it had the wrong initials on the cover


On April 25, 1983, hundreds of reporters crowded into a press conference in Hamburg, West Germany. TV cameras pointed at a table piled with small black notebooks. Some had a red wax seal stamped with an eagle and a swastika. Stern, one of Germany’s biggest news magazines, was about to make an astonishing announcement. Adolf Hitler, the Nazi dictator who started the Second World War and ordered the murder of six million Jews, had kept a secret diary. And Stern had all 60 volumes.

The magazine had paid 9.3 million German marks for the notebooks, nearly $4 million at the time. A British newspaper, The Sunday Times, had bought the right to publish them too. One of the world’s top experts on Hitler had said they were real. News outlets around the globe were racing to catch up.

Less than two weeks later, it all fell apart. The diaries were fake. They hadn’t been made by spies or a criminal genius. They had been written by a small-time seller of Nazi souvenirs, working at home, who made the covers look old by staining them with tea. One of the biggest scoops in publishing history had become one of its most embarrassing failures.

The real mystery wasn’t what Hitler had written. It was how so many smart people had been fooled.

The reporter and the forger

The story starts with two men who each had something the other wanted.

Gerd Heidemann was a well-known reporter at Stern. He was obsessed with the Nazi era. He had even bought the old yacht of Hermann Göring, one of Hitler’s top men. But the boat cost a fortune to repair and run, and it left Heidemann deep in debt. He badly needed a big story.

Konrad Kujau needed a big customer. He ran a shop in Stuttgart selling Nazi items such as helmets, medals, uniforms, and flags. Not all of it was genuine. Kujau was a skilled forger. For years, he had been quietly selling fake Nazi letters, documents, and even paintings “by Hitler” to collectors.

When the two men met, Kujau used a false name, “Dr. Fischer,” and told an exciting story. In the last chaotic days of the war, he said, a plane had left Berlin carrying boxes of Hitler’s personal belongings. It crashed in a forest near Dresden. After the war, that area became part of Communist East Germany, cut off from the West behind what was known as the Iron Curtain. Local villagers had saved what they could from the wreckage, he said, and among the boxes were Hitler’s private diaries. Kujau claimed he could smuggle them out of East Germany one volume at a time.

The clever part was that some of this was true. A plane carrying Hitler’s belongings really had crashed near Dresden in April 1945. That one real fact made the rest of the story easy to believe. It also explained why nobody had ever seen the diaries before. Heidemann was hooked, and soon his bosses at Stern were too.

A fortune for a scoop

Over the next two years, Stern poured millions into the diaries. Heidemann handed the cash to Kujau, sometimes in suitcases. Every new volume was greeted with excitement, and the price kept going up. Meanwhile, Kujau was writing as fast as he could to keep up.

It’s easy to see why Stern was so excited. Real Hitler diaries would be worth a fortune. The magazine that published them would be famous worldwide and could sell the rights to newspapers in many countries. To protect its scoop, Stern kept the diaries top secret, even from many of its own senior staff.

But that secrecy was dangerous. The more money Stern spent, the more it needed the diaries to be real. It was no longer checking a story. It was protecting a huge investment.

Stern did try to check the handwriting. It sent sample pages to handwriting experts, who compared them with real Hitler documents from the archives. The experts agreed it was a match. What nobody realized was that some of those “real” Hitler documents were also fakes, made by Kujau. The experts were comparing Kujau’s handwriting with Kujau’s handwriting. Of course, it matched.

Then came the final stamp of approval. The Sunday Times, owned by the media tycoon Rupert Murdoch, brought in Hugh Trevor-Roper, one of Britain’s most famous historians. He had written a classic book about Hitler’s last days in his Berlin bunker. After seeing the diaries in a Swiss bank vault, Trevor-Roper was convinced. He told the editors he would stake his reputation on them being real, and he wrote a newspaper article saying so.

The world’s leading Hitler expert had spoken. What could go wrong?

The truth was there all along

Almost everything went wrong, starting with the press conference itself.

By the time Trevor-Roper arrived in Hamburg, he was having second thoughts. In front of the cameras, he admitted he had doubts. Then a writer named David Irving stood up and loudly accused Stern of publishing fakes. Irving later became notorious for denying the Holocaust, so one of the first people to raise the alarm was himself a dishonest historian. The press conference turned into chaos. In London, The Sunday Times kept publishing anyway. Murdoch was reportedly told about the historian’s doubts and gave the order to go ahead.

Meanwhile, the diaries were finally getting proper scientific tests from Germany’s Federal Archives and forensic experts. The results were devastating. The paper contained a whitening chemical that wasn’t used until after the war. The bindings had synthetic threads that didn’t exist in Hitler’s lifetime. The ink was fresh. On May 6, 1983, the Federal Archives announced that the diaries were fakes, and not very good ones.

Once people looked closely, the mistakes were almost funny. Kujau had bought fancy old-style letters to decorate the covers, but he mixed them up, so several volumes said “FH” instead of “AH,” for Adolf Hitler. Much of the writing had been copied from a published book of Hitler’s speeches and padded with made-up personal details about stomach problems, bad breath, and his girlfriend, Eva Braun. And Hitler’s right arm had been badly hurt in an assassination attempt in July 1944, yet the handwriting in the diaries carried on exactly as before.

The truth had never been hard to find. The people with the most to gain had simply refused to look.

The fallout

Kujau was arrested and soon confessed. Heidemann was charged too, accused of secretly keeping much of the money that was supposed to go to the diaries’ “suppliers.” Millions of marks were never found. In July 1985, a court sent both men to prison: Kujau for four and a half years, and Heidemann for four years and eight months.

Stern’s top editors resigned, and it took the magazine years to win back its reputation. The Sunday Times had to make an embarrassing climbdown. Trevor-Roper, who had staked his reputation on the diaries, was remembered for this one terrible mistake for the rest of his life. A magazine can survive losing millions. It’s much harder to survive readers wondering whether any of its big stories can be trusted.

The diaries also did real harm. The fake entries didn’t just describe Hitler’s health problems. They quietly made him look more ordinary, even reasonable. In one passage, he complains about early attacks on Jewish buildings and demands that the people responsible be thrown out of the Nazi Party. If the world had believed the diaries, they would have helped separate Hitler from the crimes of his own regime. So the forgery wasn’t just an expensive embarrassment. It risked rewriting history.

What the scoop really cost

It’s easy to remember the Hitler diaries as a story about a clever forger and some foolish journalists. But at heart, it’s a story about the business of news and publishing.

An exclusive story can be worth a fortune, and every day spent checking the facts is a day a rival might get there first. That pressure exists across the media. Once the money is spent and reputations are on the line, it gets harder to stay objective. Evidence that supports the story is welcomed, while evidence against it is brushed aside. People tell themselves they’re being bold when they’re really being careless.

Kujau understood this better than anyone. He wasn’t a great forger. He was great at reading people. He gave the reporter the story of his career, the magazine the scoop of the century, and the historian the discovery of a lifetime. Each of them wanted the diaries to be real so badly that they stopped asking obvious questions.

Kujau didn’t fade away after prison. He became a minor celebrity, appearing on TV and openly selling paintings signed as “genuine Kujau fakes.” The diaries themselves ended up in Germany’s Federal Archives. They’re kept not as a record of Hitler’s thoughts, but as a reminder of one of the biggest media scandals of the twentieth century.

That’s the final irony. As a window into Hitler’s mind, the diaries were worthless. As a lesson in how easily people are fooled when they want to believe something, they’re priceless.

In the end, the most revealing pages weren’t the ones Kujau forged. They were the gaps in the fact-checking, and those were left by everyone else.
