On the morning of Wednesday 7 January 1953, atomic physicist John Archibald Wheeler stood on his tiptoes on the lavatory seat of a Pullman sleeper train to Washington DC and peered over into the next door cubicle at another man doing his business. Wheeler might well have asked himself what on earth he was doing. A happily married man, he risked being caught and labelled a sexual deviant. His prestigious position at Princeton, and his standing at the very top of the American scientific community, would surely be destroyed by the scandal that would ensue. But at the moment of his Peeping Tom act, Wheeler had no thought for any of those consequences. His focus was not on the man sat on the toilet seat below, but on the wall next to him, where a manila envelope was tucked behind the pipes of the lavatory system. It contained nothing less than the biggest secret on the planet – and Wheeler had to get it back. The absent-minded scientist had left it there on his visit to that cubicle just a few minutes earlier.
What happened to the H-bomb paper?
Forty-one-year-old John Wheeler (‘Johnny’ as he was known to friends) had been a key figure in the wartime Manhattan Project which developed the first atom bomb, and was currently head of Project Matterhorn B, America’s H-bomb project based at Princeton University, where he had been professor of physics since 1938. Wheeler had taken the overnight train to Washington DC to meet with representatives from the US Naval Research Laboratory about an unrelated project, but decided that he would also use his time in the capital to deliver his comments regarding the H-bomb paper to the JCAE by hand. Settling down in his berth, lower No 9, on the night of Tuesday 6 January, he had pulled out the document to read and make notes on before he went to sleep.

In the envelope was a six-page document with details of the history of the making of the H-bomb – the new terrifying weapon of mass destruction that only America possessed – and enough up to date technical detail to hugely excite a foreign power. Had he, Wheeler, thought, been burgled by a Soviet agent? When he saw the man had finished, Wheeler darted in and grabbed the manila envelope. Greatly relieved, he returned to his berth and began packing up his suitcase to go. Everything completed, he pulled out the manila envelope for a final double-check on the H-bomb document. To his complete horror, the envelope only contained another, more mundane document – the H-bomb paper had vanished.
A desperate search of his berth and the entire Pullman sleeping car, followed by a frantic tour of Washington’s Union Station rooms and restaurants to try and identify any of his fellow passengers, proved fruitless. An utterly dejected Wheeler had no alternative but to report his loss to the Joint Committee on Atomic Energy (JCAE), three of whose members rushed down to the station to add fresh eyes to the search. But eventually, soon after midday, JCAE executive director William Borden bowed to the inevitable and picked up the phone to the FBI’s Washington office.

In the five weeks that followed, Special Agent Charles Lyons, leading the investigation, was able to identify and rule out as suspects five men who had taken neighbouring berths on the Pullman train Wheeler had travelled in from Philadelphia. But there remained some worrying gaps in his knowledge. Firstly, Lyons was unable to track down an “ordinary, plainly dressed” couple, 30 to 40 years old, and their small child, who had bought a last-minute ticket from the conductor and taken up the lower and upper bunks in berth No 1. Even more tantalising was his failure to find the occupant of lower berth No 8, diagonally opposite Wheeler. Lyons had this individual’s ticket – a last-minute one, bought over the counter in Philadelphia – but frustratingly, the name written on the railroad company’s seating chart could not be identified, despite being pored over in the FBI laboratory in Chicago. This mystery man – or woman – was something like ‘Magenbright’, ‘Wagenbright’, or ‘Wagenknight’ – but no one could be sure which.

What were the contents of the H-bomb paper?
What he read that night remains highly classified, even today. But we can glean something of what it said from Wheeler’s interview with the FBI. The document confirmed that the US was on its way to a successful thermonuclear weapon (it had tested a rough and ready prototype, code-named ‘Ivy Mike’, in November 1952). It also revealed that there were several varieties of the thermonuclear weapon considered to be available for practical use. Wheeler told his inquisitors that the top-secret document also revealed technical details about the making of the ‘super’ fusion bomb – that “Lithium-6 was useful, that compression was useful, and that radiation heating provided a way to get that compression”.
The physicist believed that mention of Lithium-6 as a vital ingredient would have aroused the interest of the Kremlin. But he told FBI investigators that the “qualitative idea of radiation implosion... is the most important revelation” – and could be crucial information for Soviet atomic scientists. Wheeler had a record of carelessness with official documents, but no one seriously believed he was a Soviet spy. As Agent Lyons pursued the case, he first accounted for the movements of all Soviet diplomatic personnel on the morning of 7 January. He then initiated a probe into what he described as a “delegation of radicals” heading for the capital on Wheeler’s train. This was a group bound for the White House where they would carry placards urging the president to commute the death sentence of the Rosenbergs. FBI agents shot numerous still photographs and reels of film of this protest, and made Wheeler study it to see if he recognised any of the individuals from his train journey on 6 and 7 January. But the scientist was unable to provide a positive identification, and that trail went cold.
Fear and paranoia
The loss of the H-bomb document could not have come at a more critical time in the Cold War – and at a more febrile moment in American history. The war in Korea, now two-and-a-half years old, showed no signs of ending. An atmosphere of worry, even paranoia about communists at the heart of the government was being stoked by the witchfinder-in-chief, Joe McCarthy. Then there were the atomic spies, Julius and Ethel Rosenberg, had been tried, convicted and sentenced to death.

Since the end of December 1952, the couple’s supporters had been holding a continuous picket outside the White House, where they called on President Harry S Truman to grant the couple clemency before leaving office later that month. Now came this disappearance, which could have come right out of the pages of a spy thriller – perhaps from the pen of someone like Ian Fleming, who in 1953 was about to introduce James Bond to the world in Casino Royale.
Eisenhower’s burden
The H-bomb paper could simply have slid away from Wheeler’s grasp as he dropped off to sleep on that Tuesday night, somehow vanishing into the structure, equipment or bedding of the Pullman. But when the newly elected President Dwight Eisenhower had the task of revealing the paper’s disappearance to his National Security Council a month later, most of them were convinced it was the work of the Soviets – none more so than Vice-President Richard Nixon, who urged the FBI to carry out a complete check on each and every member of the JCAE. Eisenhower asked his deputy to liaise with FBI director J Edgar Hoover about taking into ‘custody’ all the committee’s files – before any more papers were lost. Eisenhower’s mood that day was a mixture of deep anxiety and anger that such a calamity should happen so soon on his watch.
Rarely had a president of the United States laid bare his feelings so starkly before his closest colleagues. He frankly confessed that he was “frightened”, and had no idea how to proceed. He expressed bewilderment that the item in Wheeler’s possession had been erroneously labelled as ‘Secret’ rather than ‘Top Secret’, and sent merely by registered mail to a ‘college professor’ in Princeton rather than being escorted to him by armed guard. If those responsible for this disastrous breach of security – the staff of the JCAE – had been in the army, they “should have been shot”, exploded the president. The JCAE would soon have a new chairman and a new set-up, but, as Eisenhower bemoaned, that would simply be to “lock the barn door after the horse had been stolen”.
There was no serious thought given to briefing the British about the loss. As more and more evidence was coming to light about the Cambridge Spies (the British university students recruited by the Soviets in the 1930s), and with the treachery of Klaus Fuchs (the German-born British scientist who had passed on A-Bomb secrets) still raw, there was little collaboration on the nuclear front between Washington and London. Eisenhower had been unimpressed when he had met ageing prime minister Winston Churchill in January, reflecting he was “as charming and interesting as ever – but definitely showing the effects of the passing years”.

Has the H-bomb paper ever been found?
In the end, after FBI agents all over the eastern side of the United States had interviewed hundreds of people and supervised the search of miles and miles of railway track and dozens upon dozens of railway carriages, they were none the wiser. The hunt petered out and Eisenhower had more immediate day-to-day preoccupations, primarily trying to end the war in Korea. Maybe the H-bomb paper will turn up one day in one of Putin’s files in the Kremlin. What is a fact is that only seven months later, in August 1953, the Soviet Union drew level with the US when it tested its own prototype H-bomb on the steppe in the northeast Kazakhstan.
As for ‘Johnny’ Wheeler, he escaped with a dressing-down from Gordon Dean, chairman of the Atomic Energy Committee: he was too valuable a member of the H-bomb project to be fired. Years later, musing about the incident in his memoirs, Wheeler wrote: “It is interesting, even now, to wonder whether my document was purloined by a Soviet agent. It could hardly have vanished into thin air.”

History's most famous missing documents (and one that was found)
The stories of four other items that have proved frustratingly elusive...
The ‘Q’ Gospel
Also known as the logia, the ‘Q’ Gospel is a (hypothetical) Greek-language document that many biblical scholars nevertheless believe to have been in circulation at the time of the Synoptic Gospels – Mark, Matthew and Luke – between 65 and 95 AD. The tantalising theory goes that elements of ‘Q’ surface in Mark and Luke, but a great, untapped wealth of Jesus’s teachings remain to be discovered in the original document.
The Maya Codices
The Maya civilisation (which reached its peak in the sixth century AD) featured the first complex societies, with cities, monumental architecture, writing and calendrical systems. Scribes recorded the story on codices – folding books made from tree bark. Only four of the codices survive today, with most destroyed by Spanish conquistadors and priests. But could others be hidden in tombs across southern Mexico and northern Central America?
Confucius’ Sixth Classic
Among the great Chinese philosopher’s legacy is his ‘Five Classics’: texts covering poetry, rhetoric, ancient rites, history and divination. But Confucius allegedly wrote a sixth text, on music, which is feared to have disappeared during the ‘Burning of Books and Burying of Scholars’ – a purge of ‘subversive’ works by Emperor Qin Shi Huang in the third century BC.
The Wannsee Protocol
An item that, thankfully, was found. The Wannsee Protocol comprised the minutes of a meeting held by 15 high-ranking Nazi Party and German government officials at a villa on Lake Wannsee, Berlin, in 1942, to draw up plans for the “final solution of the Jewish question”. Thirty copies of the document were created in total, with the majority destroyed by attendees in order to cover their tracks. However, one Nazi official – Martin Luther – kept his. It was discovered in 1947 by Robert Kempner, a US lawyer involved in the Nuremberg Trials, and used to secure convictions against war criminals.
