The brilliant Italian physicist Ettore Majorana vanished in March 1938 after leaving cryptic notes, a disappearance that has never been resolved and remains the subject of competing theories
Where the evidence lands: UnresolvedThat Ettore Majorana did not simply die by accident in 1938 but deliberately disappeared, engineering his own vanishing for reasons he hinted at in cryptic notes, and that he may have gone on to live for years afterward under an assumed identity, most often placed in a monastery or in South America.
Believed by: That Majorana disappeared in 1938 is universally accepted. Beyond that, biographers, physicists, and Italian investigators divide between the suicide reading, the monastery reading, and the escape-abroad reading, none of which has ever been confirmed.
The full story
The man who vanished
Ettore Majorana was, by the testimony of the people best placed to judge, one of the great physicists of the twentieth century. Born in Catania in 1906, he joined Enrico Fermi's celebrated group of young researchers in Rome and quickly became its most enigmatic member. Fermi, not a man given to hyperbole about colleagues, placed Majorana in a category of his own, comparing him to Galileo and Newton. His 1937 paper on a symmetrical theory of the electron and positron introduced the idea now called the Majorana fermion, a particle that is its own antiparticle, an idea still alive in physics today.
He was also intensely private, self-critical to the point of leaving work unpublished, and increasingly withdrawn. Late in 1937 he was appointed professor of theoretical physics at Naples, an honor granted on reputation rather than through the usual competition. A few months later he was gone.
That is the tension the whole case turns on. The subject is not an obscure figure whose exit went unnoticed but one of the most watched minds in European science, which is why his disappearance was investigated at the time and has been argued over ever since.
The documented core
Strip away the theories and a firm sequence remains. In late March 1938, Majorana did two things that later looked deliberate: he collected the salary he had let pile up uncollected, and he took his passport. On the evening of 25 March he boarded a ferry from Naples to Palermo, leaving behind a letter for Antonio Carrelli, the director of the Naples physics institute, that spoke of a decision that had become inevitable and of the distress his disappearance would cause.
The next day, from Palermo, he sent Carrelli a telegram and then a letter that seemed to reverse course, with a line usually rendered as “the sea has rejected me,” saying he would be back in Naples. He is thought to have boarded a return ferry that evening. And there the reliable record ends. He did not reappear in his known life. His family searched, appealed to the authorities, and reportedly petitioned Mussolini; nothing was found. Crucially, no body was ever recovered from the sea.
He withdrew money he had never bothered to collect and took his passport, then wrote of an inevitable decision, then seemed to take it back. Every theory begins from those same few facts.
Three ways to read the same facts
From that spare record, three main explanations have grown, and each is held by serious people. The first is suicide: a brilliant, evidently troubled man, in distress on a night crossing, went into the sea, and the letters are the trace of that intention. The second is monastic retreat: Majorana, Jesuit-schooled and deeply reclusive, withdrew from the world into a religious house, a reading given weight by reports that he approached monasteries around the time he vanished. The third is escape abroad: he staged his own disappearance and began a new life under another name.
Each theory leans on a different feature of the same evidence. The suicide reading leans on the anguished first letter and the drowning it implies. The monastery reading leans on his character and his religious formation. The escape reading leans hardest on the physical preparations, the money and the passport, which fit a planned journey more naturally than an impulsive death. It is a case where the facts genuinely underdetermine the conclusion, and reasonable readers have landed in all three places.
The writer Leonardo Sciascia, in his 1975 book on the case, pressed the deliberate-vanishing interpretation and added a moral dimension to it, suggesting a man of conscience might have chosen to disappear rather than follow physics toward the weapons it was about to enable. That framing is powerful and much loved. It is also, it should be said plainly, an interpretation, not a documented account of what Majorana actually did.
The Venezuela file, and what closing a case means
The most concrete modern development is the escape theory's strongest branch. In 2008 an Italian emigrant named Francesco Fasani told the RAI program Chi l'ha visto? that he had known Majorana in Venezuela in the 1950s, where the physicist supposedly lived under the name Bini. He offered a photograph said to show the two men together in 1955 and a postcard, reportedly taken from the man's car, sent by Majorana's uncle, the physicist Quirino Majorana.
Italian magistrates reopened the case. Forensic examiners compared the face in the photograph with Majorana's and judged it consistent. In February 2015, the Rome prosecutor's office closed the inquiry, stating there was reason to believe Majorana had been alive in Venezuela, at Valencia, at least between 1955 and 1959. Headlines treated it as the mystery solved.
Here the discipline of the file matters most. Closing an investigation and proving a fact are not the same act. The 2015 archiving expresses a prosecutor's assessment of where the evidence pointed; it is not a court's verdict, not a confirmed forensic identification, and not a documentary chain linking the man called Bini to Majorana beyond doubt. Photographic likeness across decades is suggestive and fallible, and a secondhand recollection, however sincere, is not proof. The Venezuela reading is the most substantial lead in the case. It is still a lead.
An archived case says a prosecutor found the evidence persuasive. It does not say a court proved the man in the photograph was Majorana. The difference is the whole reason this file is rated unproven.
Where it lands
Hold the layers apart and the picture is clear enough to state honestly. The disappearance is documented: Ettore Majorana left Naples by ferry in late March 1938, wrote letters that survive, and was never reliably seen again in his own identity. That much no one contests. Everything past it, the manner and the meaning of his vanishing, is unproven, which is why the file is rated exactly that.
The competing theories are not equal in flavor, but none is closed. Suicide fits the plainest facts and the anguished first letter, yet leaves the money and the passport oddly deliberate. The monastery reading fits his character and his faith, yet has never produced a verified record. The escape-abroad reading fits the preparations and drew an official inquiry to Venezuela, yet stops short of a confirmed identification. Each is possible; each lacks the one piece that would end the argument.
The responsible posture is to report the disappearance as fact, lay the theories out fairly, and resist the temptation to pick a winner the evidence cannot crown. Ettore Majorana walked onto a ferry in 1938 and out of the record. Whether the sea took him, a cloister hid him, or a false name carried him to another continent, no one has ever been able to prove. Nearly ninety years on, that remains the truest thing the case allows us to say.
Watch
What's still unexplained
- No body was ever recovered, and no death was ever registered. The absence of remains is the void at the center of the case: it neither proves he survived nor rules out a drowning whose evidence the sea simply carried away.
- The letters remain genuinely ambiguous. The inevitable-decision note and the next-day retraction can be squared with suicide, with a change of heart, or with a deliberately misleading trail, and the surviving texts do not decide between them.
- The Venezuela identification was never closed to certainty. The photograph, the postcard, and Fasani's account persuaded the prosecutors, but the man called Bini was never independently and conclusively shown to be Majorana, so the strongest survival lead stops short of proof.
- The monastery theory has never been confirmed or definitively excluded. Reports that Majorana sought out religious houses persist, yet no verified monastic record of him has surfaced, leaving that reading exactly where it has sat for decades: possible, undocumented.
Point by point
The claim: Majorana genuinely disappeared in 1938 and was never reliably seen again.
What the record shows: This is the settled core. He left Naples by ferry in late March 1938, sent letters and telegrams that survive, and did not reappear in his known life. His family searched, the police investigated, and no confirmed sighting of him in his own identity was ever recorded again. Whatever the explanation, the disappearance itself is a documented fact, not a rumor.
The claim: The notes he left prove he intended to kill himself.
What the record shows: The letters are unsettling but ambiguous, which is why they anchor several readings rather than one. The first note to Carrelli speaks of an inevitable decision and of the trouble his disappearance will cause; the next day's telegram and letter appear to retract it and announce a return. Read together, they can support suicide, but they equally support a change of mind or a staged exit. The texts do not settle the question, and treating them as a clear suicide note goes beyond what they say.
The claim: The way he prepared, taking his passport and all his money, points away from a simple suicide.
What the record shows: This is one of the strongest arguments for a deliberate vanishing. Majorana withdrew salary he had previously never bothered to collect and carried his passport, preparations that fit a planned departure better than an impulsive death. It is genuinely suggestive. It is not proof: a person intending suicide can also settle affairs, and the passport and cash were never traced to any confirmed later use. The detail deepens the mystery rather than resolving it.
The claim: He retreated into a monastery and lived out his life in religious seclusion.
What the record shows: The monastic theory rests on Majorana's Jesuit schooling and reclusive character, and on reports that he approached religious houses around the time he vanished. Sciascia and others gave it currency, and it remains one of the serious readings. But no monastery has ever produced a verified record of him, and the often-quoted line from a friar, that what matters is only that the man is at peace, is suggestive atmosphere, not documentation. The theory is plausible and unproven.
The claim: He escaped abroad and lived for years in South America under another name.
What the record shows: This is the reading the Rome inquiry ultimately favored. It draws on Francesco Fasani's testimony, a 1955 photograph said to show Majorana in Venezuela as a man named Bini, and a postcard from Majorana's uncle reportedly taken from that man's car. Italian forensic examiners judged the photographed face consistent with Majorana's. The prosecutors found it persuasive enough to close the case on that basis, but photographic likeness and a secondhand account fall short of an identification, and the man in the photo was never independently confirmed to be Majorana.
The claim: The 2015 closure of the case means the mystery is officially solved.
What the record shows: It does not, and the distinction matters. The Rome prosecutor's office archived the inquiry with the view that Majorana had likely been alive in Venezuela between 1955 and 1959. That is a decision to close an investigation, expressing a prosecutor's assessment, not a court's proven finding or a confirmed forensic match. No remains, no confessed identity, and no unbroken documentary chain establish it. It is the most concrete official statement in the file, and it is still, properly, an assessment rather than a resolution.
The claim: His scientific brilliance makes a dramatic explanation more likely than a mundane one.
What the record shows: His genius is real and well attested; Fermi's comparison to Galileo and Newton is a matter of record, and the Majorana fermion remains an active idea in physics. But brilliance is not evidence about a manner of disappearance. The romantic pull of a genius who foresaw the bomb and chose to vanish, a theme Sciascia developed, is a reason the story endures, not a reason to prefer any particular ending. The physics and the mystery are separate questions.
Other readings
Angles that don't fit neatly into the claim or its rebuttal, laid out and weighed, not endorsed.
The chose-to-vanish reading
The most widely embraced interpretation, associated above all with Sciascia, holds that Majorana did not die in 1938 but deliberately staged his own disappearance, whether from depression, a crisis of conscience over where physics was heading, or a simple wish to be left alone. The withdrawn salary and the passport give it real texture. It is a coherent and humane way to read the evidence, but it is an inference from circumstance, not a documented account of what he did, and this file presents it as one theory among several.
The unremarkable-tragedy reading
A quieter possibility is that there is no secret at all: that a brilliant, troubled man, in evident distress, went into the sea on that crossing and drowned, and that every later sighting is the pattern-seeking a famous absence invites. This reading has the virtue of fitting the plainest facts, the night ferry, the anguished letter, the vanished man, without requiring a decades-long hidden life. It cannot be proven either, since no body was found, but it is the counterweight to the romantic theories and belongs in any honest account.
Timeline
- 1906-08-05Ettore Majorana is born in Catania, Sicily, into a prominent family. He shows prodigious mathematical talent early and, in the late 1920s, joins Enrico Fermi's group of young physicists in Rome, the so-called Via Panisperna boys.
- 1932Majorana reportedly works out the existence of a neutral nuclear particle, anticipating the neutron, but characteristically declines to publish; James Chadwick's discovery is credited that same year. Fermi later describes Majorana as a once-in-a-century genius, comparing him to Galileo and Newton.
- 1937Majorana publishes 'A Symmetrical Theory of the Electron and Positron,' introducing what becomes known as the Majorana fermion, a particle identical to its own antiparticle. On the strength of his reputation he is appointed professor of theoretical physics at Naples without the usual competition.
- 1938-03-25In Naples, Majorana withdraws the salary he had let accumulate and takes his passport. He leaves a letter for Antonio Carrelli, director of the physics institute, speaking of a decision that has become inevitable, and boards an evening ferry bound for Palermo.
- 1938-03-26From Palermo, Majorana sends Carrelli a telegram and a follow-up letter that appear to walk back the earlier note, with the line often rendered as 'the sea has rejected me,' saying he will return to Naples. He is believed to have boarded a return ferry that evening.
- 1938-03Majorana fails to arrive or reappear in Naples. His family launches an urgent search, appealing to the authorities and reportedly to Mussolini himself; police inquiries and a reward yield no confirmed sighting. No body is ever recovered from the sea.
- 1938Two early explanations take hold almost at once: that he drowned, by accident or by suicide, on the crossing, and that he withdrew deliberately into seclusion, possibly a religious retreat, a reading his own family is said to have found plausible given his temperament.
- 1975The Sicilian writer Leonardo Sciascia publishes 'La scomparsa di Majorana,' arguing that Majorana chose to disappear, and floating the idea that a man of his conscience may have fled the coming physics of the bomb; the book fixes the mystery in the public imagination.
- 2008An Italian emigrant, Francesco Fasani, tells the RAI television program 'Chi l'ha visto?' that he knew Majorana in Venezuela in the 1950s, where the physicist supposedly lived under the name Bini. His account, a photograph, and a postcard prompt Italian magistrates to reopen the case.
- 2015-02The Rome prosecutor's office closes the reopened inquiry, stating there is reason to believe Majorana was alive and living in Venezuela, at Valencia, at least between 1955 and 1959. The file is archived; the conclusion is an official view, not a confirmed identification.
Unresolved. One fact is beyond dispute: Ettore Majorana, one of the most gifted theoretical physicists of his generation, boarded a night ferry between Naples and Palermo in late March 1938 and was never reliably seen again. What is unproven is everything after that, because no body was ever found and no single account has been confirmed. This file separates the documented core, a real disappearance preceded by cryptic letters and telegrams, from the competing explanations that have grown around it: suicide at sea, withdrawal into a monastery, or a deliberate escape into a new life abroad. In 2015 the Rome prosecutor's office closed a long-reopened inquiry with the view that Majorana had likely been alive in Venezuela between 1955 and 1959, living under another name; that is an official conclusion of an archived case, not a proven identification, and it is reported here as exactly that. The site asserts none of the theories. The honest rating is that Majorana vanished and the reason has never been established.
