Ettore Majorana - theoretical physicist

‘Genius’ who disappeared in mysterious circumstances

Ettore Majorana was seen by colleagues
as both a genius and an enigma

The theoretical physicist Ettore Majorana, whose work in the 1930s is still reaping profound benefits in nuclear, medical and computer science but ended with his sudden disappearance in 1938, was born on this day in 1906 in Catania in Sicily.

Majorana, who became part of a team of scientists working with the Nobel Prize-winning nuclear physicist Enrico Fermi in Rome, was regarded as a genius by his contemporaries, capable of solving in his head problems that others might take years to unravel.

While much of Majorana’s work in such areas as particles, their exchange interaction, matter and anti-matter, might seem dry and beyond the comprehension of non-scientists, it has consequences still seen today.

More reliable designs for nuclear reactors, advancements in medical isotopes used in cancer scans and treatments, more precise radiation dosages in radiotherapy, plus technological developments in quantum computing, can all be traced back to theories put forward by Majorana.

Yet his mysterious disappearance when seemingly on the cusp of achieving immortal status in the scientific world has given rise to as much discussion as the legacy of his work.

Majorana hailed from a scientific family. His father, Fabio, was an engineer in the telegraph and telephone industries, while an uncle, Quirino Majorana, was an experimental physicist at the University of Bologna.

Ettore Majorana enrolled at the Sapienza University of Rome to study engineering in 1923, but switched to physics in 1928 with the encouragement of Emilio Segrè, a fellow student who would go on to become a leading nuclear physicist and radiochemist and, like Fermi, a winner of the Nobel Prize.

A brilliant student, Majorana was still in his early 20s when he joined the group of scientists assembled by Fermi, professor of theoretical physics at the University of Rome, who became known as the "Via Panisperna boys", named after the street address of their laboratory.

Majorana's disappearance, as reported by the
Milan newspaper Domenica del Corriere

Yet, for all his brilliance, Majorana as a person was an enigma. Unlike some of his colleagues, he never craved fame or recognition. He was rarely satisfied with a piece of work and would seldom publish his findings. Colleagues would describe him as distant and withdrawn.

He joined Mussolini’s National Fascist Party in 1933 and spent time in Leipzig, working with Werner Heisenberg, a theoretical physicist who would in time become a scientist on Germany’s nuclear programme in World War Two. The Nazis came to power while Majorana was there and he expressed solidarity with many of Hitler’s views and policies.

Shortly before his disappearance, he had been appointed a professor of theoretical physics at the University of Naples. 

He vanished during or after a trip to Palermo in March, 1938. It was thought he might have been planning to visit his friend, Emilio Segrè, who was a professor at the university there.

But a letter sent by Majorana while he was in the Sicilian capital suggested a different reason for his journey. It was to Professor Antonio Carrelli, the director of the Physics Institute at the University of Naples, seemingly signalling his resignation. It spoke of making “a decision that has become unavoidable”.

Confusingly - before the original letter arrived - Carrelli received a telegram from Majorana apparently withdrawing his resignation and saying that he was returning to Naples.

Majorana bought a ticket for a boat back to Naples but while porters found luggage in his cabin after the passengers had disembarked, there was no sign of Majorana, nor any proof that he had ever been on board. 

Majorana's name is among those on a plaque marking
the Rome base of the "Via Panisperna boys"

Multiple theories have been put forward to explain his disappearance, including suicide, murder, a desire to start a new life in another country, or even that he had decided to seek the anonymity of life in a monastery.

Proponents of the suicide theory suggested that Majorana realised that the research in which he had been involved would eventually lead to the creation of highly destructive weapons and suffered intolerable remorse as a consequence.

Others theorised that, during his time in Germany, he had learned too much about Nazi ambitions to develop a nuclear bomb and was murdered by Nazi agents.

But with no body ever found, and no witnesses to any suicide or murder, neither could be proved.

Leonardo Sciascia, the Sicilian writer, supported the idea that Majorana was appalled at the thought of his works being used to create nuclear explosives but suggested that, as a devout Catholic, he would have more likely sought to live an anonymous life in a monastery or other religious retreat than to take his own life.

The official explanation - reached 77 years after he vanished - is that he emigrated to South America.

A postage stamp issued on the
centenary of Majorana's birth

This gained credence in 2011 when a supposed witness made a statement about meeting Majorana in Buenos Aires, the capital of Argentina, in the years after World War Two. A photo also came to light, taken in Argentina 1955 of a man bearing several facial similarities to Majorana.

The case looking into his disappearance was reopened in Italy as a result. Four years later, the Rome Attorney’s Office was sufficiently satisfied that Majorana had been alive and living in Venezuela in the 1950s to declare the case closed, with no crime to investigate.

In 2025, the civil section of the Court of Rome issued a decree declaring Majorana’s presumed death.

Today, academics in the field of theoretical physics encounter his name recalled in such things as the Majorana equation, Majorana fermions, and Microsoft’s Majorana 1, a device used in the development of quantum computers. 

A Majorana Prize is awarded annually for outstanding contributions to theoretical and mathematical physics. A postage stamp commemorating his life was issued in 2006 on the centenary of his birth.

Catania's Cattedrale di Sant'Agata is a beautiful
example of Sicilian Baroque architecture

Travel tip:

The city of Catania, which is located on the east coast of Sicily facing the Ionian Sea, is one of the ten biggest cities in Italy, with a population including the environs of 1.12 million. A little like Naples, which sits in the shadow of Vesuvius, Catania lives with the constant threat of a natural catastrophe, more so given that its neighbour, Mount Etna, is active and regularly erupts, if not with explosive force. Catania has also been virtually destroyed by earthquakes twice, in 1169 as well as 1693. As such it has a reputation for living life to the full. In the Renaissance, it was one of Italy's most important cultural, artistic and political centres and enjoys a rich cultural legacy today, with numerous museums and churches, theatres and parks, and many restaurants. Catania’s historic centre is a showcase of Sicilian Baroque, rebuilt after the 1693 earthquake using the city’s signature black lava stone. A notable example is the Duomo of Sant’Agata, a monumental cathedral, home to the relics of St Agatha and framed by a grand piazza, at the centre of which is the Fontana dell’Elefante, the symbol of the city - a Roman basalt elephant supporting an obelisk.

The University of Naples Federico II has its
headquarters building in Corso Umberto I

Travel tip:

The University of Naples Federico II, where Ettore Majorana was appointed a professor shortly before he disappeared, was founded in 1224 by the Emperor Frederick II. It is one of Europe’s most historically significant universities: the oldest public, secular university in the world.  One of its most famous students was the theologian and philosopher, Thomas Aquinas, who went on to lecture there in the 13th century. Other alumni include Enrico De Nicola, the first President of the Italian Republic, and two other presidents, Giovanni Leone and Giorgio Napolitano. The university’s main locations include the central headquarters in Corso Umberto I, with additional sites in Portici, Torre del Greco, Anacapri, Avellino, and Bellizzi. A former college built in the 16th century in Via Paladino, in the area of Spaccanapoli, has been one of the university’s main buildings since 1777. With more than 70,000 students, 180 degree programmes across 26 departments, and strong research output, especially in engineering, medicine, and agricultural sciences, it ranks second among Italy’s major universities and is the leading university in Southern Italy.

Lorenzo di Pierfrancesco de’ Medici - banker

Art enthusiast who was Botticelli’s major patron

The Florentine banker and politician Lorenzo di Pierfrancesco de’ Medici, who was a significant figure in Renaissance art as the main sponsor and patron of the painter Sandro Botticelli, was born on this day in 1463.  The great-grandson of Giovanni di Bicci de’ Medici, the founder of the Medici bank, Lorenzo di Pierfrancesco belonged to the junior, sometimes known as ‘Popolani’ branch of the House of Medici.  In 1476, when he and his brother, Giovanni, were still boys, their father, Pierfrancesco de’ Medici the Elder, died. They became wards, effectively, of their cousin, Lorenzo il Magnifico - Lorenzo the Magnificent - a member of the senior branch of the family and the effective ruler of Florence.  Relations between the two branches were tense and not helped when Lorenzo di Pierfrancesco discovered, on becoming an adult, that Lorenzo il Magnifico had plundered a considerable sum from he and his brother’s joint inheritance.

Giovanni Spadolini - politician

The first non-Christian Democrat to lead Italian Republic

Giovanni Spadolini, who was the Italian Republic’s first prime minister not to be drawn from the Christian Democrats and was one of Italy's most respected politicians, died on this day in 1994.  In a country where leading politicians and businessmen rarely survive a whole career without becoming embroiled in one corruption scandal or another, he went to the grave with his reputation for honesty intact.  Although he was an expert on Italian unification and became a professor of contemporary history at the University of Florence when he was only 25, a background that gave him a deep knowledge of Italian politics, he first built a career as a journalist.  He became a political columnist for several magazines and newspapers, including Il Borghese, Il Mondo and Il Messaggero, and was appointed editor of the Bologna daily II Resto del Carlino in 1955, at the age of 30.  Read more…

Anita Garibaldi – national heroine of Italy

Brave wife of Giuseppe Garibaldi was a freedom fighter

Anita Garibaldi, the Brazilian wife of Italy’s revolutionary hero Giuseppe Garibaldi, died in the arms of her husband on this day in 1849 in Mandriole, near Ravenna, in Emilia-Romagna.  She was pregnant and also ill with malaria, but she was having to retreat from Austrian and French troops with the Garibaldian Legion. After her death, her body had to be hurriedly buried, and it was said to have been later dug up by a dog.  A Brazilian revolutionary, Anita had fought alongside Garibaldi in his campaigns, after meeting him in her home country in 1839.  She was born Ana Maria di Jesus Ribeiro in 1821 in Laguna in Brazil. She was the third of ten children born to a poor family.  Anita met Garibaldi, who was a sailor of Ligurian descent, after he had left Europe in 1836 and was fighting on behalf of the separatist Riograndense republic in southern Brazil.

Pope Urban VII

Pope for just 12 days but introduced world's first smoking ban

Pope Urban VII was born Giovanni Battista Castagna on this day in 1521 in Rome.  Although his 12-day papacy in 1590 was the shortest in history, he is remembered as being the first person in the world to declare a ban on smoking.  He was against the use of tobacco generally, threatening to excommunicate anyone who ‘took tobacco in the porchway of, or inside a church, whether it be by chewing it, smoking it with a pipe, or sniffing it in powdered form through the nose’.  The ban is thought to have been upheld for the most part until 1724, when Pope Benedict XIII, himself a smoker, repealed it.  Castagna was the son of a nobleman of Genovese origin and studied in universities all over Italy. He obtained a doctorate in civil law and canon law from the University of Bologna.  He served as a constitutional lawyer to Pope Julius III and was then ordained a priest.  Read more…

Lucrezia Maria Romola de’ Medici – noblewoman

Daughter of Lorenzo the Magnificent supported popes and poets

Lucrezia Maria Romola de’ Medici, who as a newborn baby inspired Sandro Botticelli’s depiction of baby Jesus in one of his paintings, was born on this day in 1470 in the Republic of Florence.  After her brother became Pope Leo X, Lucrezia helped him fund papal building projects in Florence and Rome. She also raised money to pay a ransom and secure the release of her husband when he was taken prisoner by the Holy Roman Emperor Charles V.  She had 11 children, many of whom were to play an important part in the history of Renaissance Europe.  Lucrezia was the eldest daughter of Lorenzo de’ Medici and Clarice Orsini. After her birth, Botticelli painted Our Lady of the Magnificat, which is now in the Uffizi Gallery in Florence, and used her image as a baby as the model for the figure of the newborn Christ in his masterpiece.  Read more…

Imperia Cognati - courtesan

Prostitute who became a celebrity

Imperia Cognati, who acquired celebrity status in Rome in the early 16th century as a courtesan to a number of rich and powerful figures, was born on this day in 1486.  Courtesans were originally the female companions of courtiers of the papal court, whose duties required them to be educated and familiar with etiquette, so that they could participate in the formalities of court life and take part in polite conversation.  In time, however, in some cases their companionship became of a more intimate nature and they became the mistresses of their courtiers, who in the papal court were clerics not permitted to marry.  It was common, too, for courtesans to be the companions of several clients simultaneously.  They were in effect a new class of prostitute, refined and educated enough to hold their own in polite society.  Read more…

Omero Antonutti - actor and voice dubber

Narrator of Oscar-winning Life is Beautiful had long career

The actor Omero Antonutti, who acted in around 60 films and was the Italian voice of many international stars, was born on this day in 1935 in Basiliano, a village about 13km (eight miles) west of the city of Udine in the Friuli-Venezia Giulia region of northeast Italy.   His most acclaimed performance came in Padre padrone, a 1977 film directed by Paolo and Vittorio Taviani, a Palme d’Or winner at Cannes that was considered by many critics to be the co-directing brothers’ finest work.  Antonutti worked with the Taviani brothers again on La notte di San Lorenzo (1982), which won the Grand Prix du Jury at Cannes, and Kaos (1984), in which he took the part of the playwright Luigi Pirandello in a film based on some of Pirandello’s own short stories.  He was often asked to portray significant figures in dramatisations of real-life events, such as Roberto Calvi, the ill-fated chairman of the Banco Ambrosiano.

La Scala - opera and ballet theatre

First night at the world’s most famous opera house

Milan’s Teatro alla Scala was officially inaugurated on this day in 1778.  Known to Italians simply as La Scala, the theatre has become the leading opera house in the world and many famous artists have appeared there. A fire had destroyed the Teatro Regio Ducale, which had previously been the home of opera in Milan. A group of 90 wealthy patrons, the owners of private boxes in the theatre, wrote to Archduke Ferdinand of Austria-Este asking that a new theatre be built.  The new theatre was built on the site of the former Church of Santa Maria alla Scala, which is how the theatre got its name. The church was deconsecrated and demolished to make way for the theatre.  With the cost of the project met by the 90 patrons, who paid in advance for boxes, the new theatre was designed by neoclassical architect Giuseppe Piermarini and at the official opening on 3 August 1778, Antonio Salieri’s opera L’Europa riconosciuta was premiered.  Read more…

Antonio da Sangallo the Younger - architect

Talented Florentine was commissioned by the Popes

Antonio da Sangallo the Younger, who left his mark on Rome during the Renaissance, died on this day in 1546 in Terni in Umbria.  Sangallo was the chief architect on St Peter’s Basilica from 1520 onwards and built many other beautiful churches and palaces in the city and throughout the Papal States.  He was born Antonio Cordiani in Florence in 1484. His grandfather had been a woodworker and his uncles, Giuliano and Antonio da Sangallo, were architects.  The young man followed his uncles to Rome to pursue a career in architecture and ended up taking the name Sangallo himself.  He became an assistant to Donato Bramante and started by preparing sketches for his master.  Recognising his talent, Bramante gave Sangallo projects to complete with no more than an outline of the design and motifs.  Sangallo’s first major commission was for the Church of Santa Maria di Loreto in 1507.  Read more…

Francesco Ferruccio - military leader

Florentine soldier celebrated in Italy’s national anthem 

Francesco Ferruccio, the military leader whose heroic attempt to defend Florence against the powerful army of the Holy Roman Empire is recalled in Italy’s national anthem, died on the battlefield on this day in 1530.  A Florentine by birth, Ferruccio had been charged with leading the army of the Republic of Florence as the city came under attack during the War of the League of Cognac, when the Pope Clement VII connived with the emperor Charles V to overthrow the republic and restore power in Florence to his own family, the Medici.  Despite being outnumbered, Ferruccio’s soldiers engaged the Imperial forces at Gavinana, just outside Florence, killed their leader and drove them back, only for the enemy to be reinforced by the arrival of 2,000 German mercenaries under the leadership of the condottiero, Fabrizio Maramaldo.  Read more...

Book of the Day: The Renaissance Courtesan in Words, Letters and Images: Social Amphibology and Moral Framing, by Eugenio L Giusti

Although throughout history women had been confined to enclosed spaces, the advent of courtly life and culture required that men and women would share and interact in public arenas like the princely courts, intellectual salons, or gambling houses. But also in all of these public spaces behavioural rules and regulations aimed to control women’s bodies by equating honesty with chastity. The Renaissance Courtesan in Words, Letters and Images analyses how in the 16th, 17th and 18th centuries women in general, and in particular prostitutes and courtesans, repeatedly challenged those rules in the attempt to affirm their individual freedom. This analysis has three complementary approaches: first, an historical approach where census documents and sumptuary laws are investigated in order to describe the ways in which the political establishment unsuccessfully attempts to enforce its rules over women’s behaviour; second, a literary approach where works by Castigione, Aretino, Bandello, and Veronica Franco are analysed in order to emphasise the terminological proximity between the legal and the literary languages, and the evolution of the term «courtesan» with its attribute «honest»; a third - visual - approach looks at prints of women’s clothing, made by 16th and 17th century artists.

Eugenio Giusti is Associate Professor of Italian at Vassar College in New York State. He received a PhD in Medieval Italian Literature from New York University.

NEW - Fabio Testi - actor

Successful career followed breakthrough role in De Sica classic 

The actor Fabio Testi, whose role in an Oscar-winning 1970 drama directed by Vittorio De Sica remains his most famous, was born on this day in 1941 in Peschiera del Garda, a town on the southern shore of Lake Garda.  Testi played Giampiero Malnate, one of two young men competing for the affections of Micòl, the daughter of a wealthy Jewish intellectual in De Sica’s The Garden of the Finzi-Continis, with which the director won one of his four Academy Awards.  The performance led Testi to be named best new actor at the 1971 Golden Globes, the awards made annually by foreign journalists accredited in Italy.  Appearing in The Garden of the Finzi-Continis made Testi famous in Italy, representing a major breakthrough just two years after earning his big-screen debut.  Although nothing he subsequently did achieved similar heights, he went on to have a long and successful career, appearing in more than 100 films.

Pietro Mascagni – composer

One opera was enough to build reputation of musician

Pietro Mascagni, the creator of the opera Cavalleria rusticana, died on this day in 1945 in Rome, at the age of 81.  Cavalleria rusticana was an outstanding success when it was first performed in Rome in 1890 and was said to have single-handedly brought the Verismo movement, in which the characters were ordinary people rather than gods, mythological figures or kings and queens, into Italian opera.  The opera’s beautiful intermezzo was used in the soundtrack of the 1980 film Raging Bull and a production of the opera was used as the setting for the climax of the 1990 film The Godfather Part III, with Michael Corleone’s son Anthony playing Turridu, the opera’s male protagonist. The film ends with the intermezzo playing.  In 2001 Andrea Bocelli recorded a song entitled Mascagni on his Cieli di Toscana album incorporating an excerpt from Cavalleria rusticana. Read more…

Bologna railway station bombed

Biggest terrorist atrocity in Italy's history killed 85

Italy suffered the most devastating terrorist outrage in its history on this day in 1980 with the bombing of Bologna's main railway station.   A massive 23kg (51lbs) of explosive packed into a suitcase left in a crowded waiting room was detonated at 10.25am, creating a blast that destroyed much of the main building of the station and badly damaged a train on one of the platforms.  Many people, locals and tourists, Italians and foreign nationals, were caught up in the explosion. Some were killed instantly, others died as a result of the roof of the waiting room collapsing on to the victims. There were 85 deaths and more than 200 other people were wounded.  The bomb was clearly placed to cause mass casualties. It was the first Saturday in the traditional August holiday period and the explosive-laden suitcase was left in a room with air conditioning, then still relatively rare in Italy. Read more… 

Francis Marion Crawford – author

Novelist found inspiration while living in Sorrento

The American writer Francis Marion Crawford was born on this day in 1854 in Bagni di Lucca in Tuscany.  A prolific novelist, Crawford became known for the vividness of his characterisations and the realism of his settings, many of which were places he had visited in Italy.  He chose to settle in later life in the coastal resort of Sorrento in Campania where he even had a street named after him, Corso Marion Crawford.  Crawford was the only son of the American sculptor, Thomas Crawford. He spent his childhood going backwards and forwards between Italy and America and studied at various American and European Universities.  He spent some time in India where he found the inspiration for his first successful novel, Mr Isaacs, which was published in 1882.  In 1883 he returned to Italy to settle there permanently.

Carlo Savina - film composer and musical director

Worked on major scores including The Godfather and Fellini’s Amarcord

Musical director Carlo Savina, who arranged soundtracks written by such luminaries of the film music industry as Ennio Morricone and Nino Rota, was born on this day in 1919 in Turin.  Savina was also a prolific film composer in his own right and is credited with writing or arranging the scores of at least 200 movies in a career spanning more than 35 years. He won a David di Donatello award for Best Music for the 1985 crime drama The Pizza Connection, directed by Damiano Damiani and starring Michele Placido, a version of which was released in the United States as The Sicilian Connection.  Yet Savina is more frequently remembered for his work with Rota on the multi-award winning soundtrack of the first film in Francis Ford Coppola’s The Godfather trilogy in 1972 and with Federico Fellini the following year on Amarcord.

Book of the Day: Vittorio De Sica: The Art of Stage and Screen, by Flavio De Bernardinis

Vittorio De Sica (1901-1974) is a unique film artist. While Rossellini and Visconti came into being with neorealism, De Sica matured through neorealism.  As an already established artist, he put himself wholly on the line and played a gambit that revolutionized Italian and world cinema. From 1923, the year he made his debut in a minor role with Tatiana Pavlova’s theatre company, and over the following twenty years of his career in Italian theatre and cinema, he sowed the seeds of the neorealism that would lead to his 1943 I bambini ci guardano (The Children are Watching Us). Vittorio De Sica. The Art of Stage and Screen tells his whole story, before, during and after neorealism. From the early days in theatre to his role behind the camera, De Sica runs the gauntlet of the history of the performing arts in Italy at a crucial point in time: the years straddling the decline of the theatre of the great stars of the 19th century tradition to the birth of the director’s theatre, the “talkies”, songs and gramophone records, up to the formidable season of “Sciuscià” (Ragazzi) (Shoeshine, 1946) and Ladri di biciclette (Bicycle Thieves, 1948).  

Flavio De Bernardinis (Rome, 1957) is a scholar of the history and aesthetics of cinema and entertainment. He is the author of L’arte secondo Kubrick (2003) and Arte cinematografica: il ciclo storico del cinema da Argan a Scorsese (2017). He teaches Film History and the Analysis of Film Language at the Centro Sperimentale di Cinematografia.
