- Ettore Majorana - theoretical physicist 

‘Genius’ who disappeared in mysterious circumstances

The theoretical physicist Ettore Majorana, whose work in the 1930s is still reaping 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 beyond the comprehension of non-scientists, it has consequences still seen today.  More reliable nuclear reactors, advancements in cancer scans and treatments, more precise radiation dosages in radiotherapy, plus developments in quantum computing, can all be traced back to theories put forward by Majorana.

Leonardo Leo - composer

Baroque musician known for his sense of humour

A prolific composer of comic operas, Leonardo Leo was born on this day in 1694 in San Vito degli Schiavoni (now known as San Vito dei Normanni) in Puglia.  His most famous comic opera was Amor vuol sofferenza - Love requires suffering - which he produced in 1739. It later became better known as La finta frascatana, and received a lot of praise, but Leo was equally admired for his serious operas and sacred music. He has been credited with forming the Neapolitan style of opera composition.  He was enrolled as a young boy as a student at the Conservatorio della Pietà dei Turchini in Naples and was a pupil first of Francesco Provenzale and later of Nicola Fago. It has been speculated that he may have been taught by Alessandro Scarlatti, but it has since been proved by music historians that he could not possibly have studied with the composer.  Read more…

Felice Casson - politician and magistrate

His investigations revealed existence of Operation Gladio

Felice Casson, the magistrate whose investigations exposed the existence of the NATO-backed secret army codenamed Gladio, was born on this day in 1953 in Chioggia, near Venice.  A former mayor of Venice and a Democratic Party senator, Casson devoted much of his career in the judiciary to fighting corruption and rooting out terrorists.  In 1984, his interest in terrorism led him to examine the unsolved mystery of the Peteano bombing in 1972, in which three Carabinieri officers were killed by a car bomb placed under an abandoned Fiat 500 in a tiny hamlet close to the border with Yugoslavia. Casson discovered flaws in the original investigation into the bombing, which at the time was blamed on the left-wing extremist group the Red Brigades, who would later be responsible for the kidnap and murder of Aldo Moro, a former prime minister.  Read more…

Antonio Cesti – opera composer

Singer and organist wrote operas and church music

Composer Pietro Marc’Antonio Cesti was baptised on this day in 1623 in Arezzo in Tuscany. It was also probably the date of his birth.  One of the leading composers of the 17th century, Cesti is said to have written about 100 operas, although only 15 are known today.  He joined the order of Friars Minor, or Franciscans, a Catholic religious group founded by St Francis of Assisi in 1637.  Cesti studied first in Rome and then moved to Venice, where his first known opera, Orontea, was produced in 1649.  In 1652 he became chapel master to Archduke Ferdinand of Austria at Innsbruck and from 1669 he was vice chapel master to the imperial court in Vienna.  Throughout the 17th century his operas were widely performed in Italy. His most famous operas, Il pomo d’oro, Dori and Orontea, have survived to this day.  Read more…


Franco Lucentini – author

Writer was one half of a famous thriller-writing partnership

The novelist Franco Lucentini, who achieved success with Carlo Fruttero in a remarkable literary association, died on this day in 2002 in Turin.  A news correspondent and editor, Lucentini met Fruttero in 1953 in Paris and they started working together as journalists and translators.  But they were best known for the mystery thrillers they produced together.  After choosing a subject they would take it in turns to write and then edit the material until a novel was complete.  Their most popular books were La donna della domenica (The Sunday Woman), which was later made into a film and La verità sul caso D (The D Case), which was based on an unfinished work by Charles Dickens, The Mystery of Edwin Drood.  Lucentini fell foul of the Fascist regime while studying at the University of Rome because of distributing anti-war messages among his fellow students.

Antonio Barberini – Cardinal

Pope’s nephew amassed fortune and became patron of the arts

Catholic cardinal, military leader and patron of the arts, Antonio Barberini was born on this day in 1607 in Rome.  As one of the cardinal-nephews of Pope Urban VIII he helped to shape the politics, religion, art and music of 17th century Italy and took part in many papal conclaves.  He is sometimes referred to as Antonio the Younger, or Antonio Barberini Iuniore, to distinguish him from his uncle, Antonio Marcello Barberini.  Antonio was the youngest of six children born to Carlo Barberini and Costanza Magalotti. Like his brothers, he was educated at the Collegio Romano.  His brother, Francesco Barberini, became Grand Inquisitor of the Roman Inquisition.  His uncle, Maffeo Barberini, who was elected as Pope the day after Antonio’s 16th birthday and became Pope Urban VIII, was notorious for nepotism and appointed Antonio as a cardinal.

Book of the Day: The Pope of Physics: Enrico Fermi and the Birth of the Atomic Age, by Gino Segrè and Bettina Hoerlin

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called the Pope by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions.  This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics. Fleeing fascism and anti-semitism, Fermi became a leading figure in America's most secret project: building the atomic bomb. The last physicist who mastered all branches of the discipline, Fermi was a rare mixture of theorist and experimentalist. His rich legacy encompasses key advances in fields as diverse as comic rays, nuclear technology, and early computers.  In The Pope of Physics, Gino Segrè and Bettina Hoerlin bring this scientific visionary to life. An examination of the human dramas that touched Fermi’s life as well as a thrilling history of scientific innovation in the 20th century, this is the comprehensive biography that Fermi deserves.

Gino Segrè - nephew of Nobel laureate physicist Emilio Segrè - is an Italian-American physicist and professor emeritus at the University of Pennsylvania. He is the author of several books on the history of science, particularly on atomic physics.  Bettina Hoerlin taught healthcare disparities at the University of Pennsylvania and is a former Health Commissioner of Philadelphia. She was brought up in Los Alamos, New Mexico, which gained notoriety as the base for the highly secretive Manhattan Project, set up during World War Two to produce the first nuclear weapons.
