Alessandro Cruto - inventor

Produced light bulb hailed as better than Edison’s

Alessandro Cruto was always
fascinated by science

The inventor Alessandro Cruto, whose attempts to create artificial diamonds instead led him to develop a light bulb that outperformed that of his contemporary, Thomas Edison, was born on this day in 1847 in Piossasco, a village near Turin.

Younger than his American counterpart by just three months, Cruto hit upon his idea after attending a conference held by Galileo Ferraris, the pioneer of alternating current, where Edison’s attempts to find a suitable filament for incandescent light bulbs were discussed.

Cruto eventually opened a factory that eventually made up to 1,000 light bulbs per day but quit the company after seven years to return to his first love, inventing.

The son of a construction foreman, Cruto enrolled at the University of Turin to study architecture but was more interested in attending physics and chemistry lectures, eager to advance his knowledge. It was after attending one of these lectures that he hit upon the idea that he could produce artificial diamonds by crystallising carbon.

In 1872, he opened a small workshop in his home village. In the September of the following year, his experiments resulted in him creating a dense carbon material that was hard enough to scratch glass. But it did not resemble anything that could be recognised as a synthetic diamond.

He continued to study this material for many years. In 1879, on his 32nd birthday, he attended the conference hosted by Ferraris and realised the graphite he had created might be a suitable material for an effective filament for an electric light bulb.

Cruto's process resulted in the deposition of graphite on thin platinum filaments in the presence of gaseous hydrocarbons. Subjected to high temperatures, this created thin filaments of super-pure graphite. 

In 1882, he attended the Electricity Expo at Munich, where his graphite filaments, which produced a strong, white light, outperformed Edison’s carbon-coated bamboo filaments, which gave off a rather less effective yellow light and burnt out more quickly. 

The following year, Cruto’s bulbs illuminated the centre of Piossasco, enabling his home village to claim to be the first in Italy to be illuminated by electricity, rather than by the dim gas lamps that until then were the sole source of light in Italy’s towns and cities once the sun had gone down.

After exhibiting again at the Turin Expo in 1884, he generated sufficient interest that he decided to produce bulbs on a commercial scale.

Cruto established a manufacturing plant in order
to make light bulbs on a commercial scale

A year later, having found a suitable site for a production facility a short distance from Piossasco at Alpignano, he opened his factory under the name of A Cruto and Company.

With limited financial backing, the odds against his company becoming the dominant player in the light bulb market even in Italy were long. With much more financial muscle, the Italian Edison Company was too big a competitor. Edison installed a thermo-electric power station in Milan and supplied the bulbs for all the properties it served.

Cruto remained at the helm of his business until 1889 and only when its output hit 1,000 light bulbs a day did he take a step back. In 1893, after some major disagreements with managers he had appointed in his place, he resigned in order to return to his workshop to focus on new inventions.

The factory was sold a number of times, went bankrupt and was eventually acquired by Philips in 1927.  The Cruto name remained in use for some years after Alessandro had ceased to be involved, with examples in existence that were manufactured as late as 1902.

Cruto spent the rest of his days dividing his time between his family and his workshop. He died in 1908, his important contribution to the development of artificial light largely forgotten.

The Church of San Vito dominates the parish
of the same name in Piossasco

Travel tip:

Piossasco, where Alessandro Cruto was born and opened his first workshop, is a town not far from Turin, halfway between Turin and the beautiful and elegant town of Pinerolo, famous for being the ‘home’ of panettone and other enriched breads. A village when Cruto was growing up, it has expanded into a town of more than 18,000 people. Situated about 20km (12 miles) southwest of the Piedmont capital, Piossasco overlooks the beautiful Parco Naturale del Monte San Giorgio, and has some notable historic buildings such as the Castello Ai Nove Merli di Piossasco, which has medieval origins and occupies a panoramic position commanding sweeping views of the Pinerolese and Valsusa areas. The San Vito parish of Piossasco is notable for the church of the same name, which evolved from a former monastery and was largely built at the end of the 16th century with a Baroque facade added in the 19th century.

Turin is famous for its Savoy palaces, 
including the 16th century Palazzo Reale

Travel tip:

The city of Turin, once the capital of Italy and traditionally seat of the Savoy dynasty, is best known for its royal palaces but tends to be overlooked by visitors to Italy, especially new ones, who flock first to Rome, Florence, Venice and Milan. Yet as an elegant, stylish and sophisticated city, Turin has much to commend it, from its many historic cafés to 12 miles of arcaded streets and some of the finest restaurants in Piedmont. To enjoy Turin’s café culture, head for Via Po, Turin’s famous promenade linking Piazza Vittorio Veneto with Piazza Castello, or nearby Piazza San Carlo, one of the city’s main squares. In the 19th century, these cafès were popular with writers, artists, philosophers, musicians and politicians among others, who would meet to discuss the affairs of the day.

Sergio Gonella - football referee

First Italian to referee a World Cup final

Sergio Gonella, the first Italian football referee to take charge of a World Cup final, was born on this day in 1933 in Asti, a city in Piedmont best known for its wine production.  Gonella was appointed to officiate in the 1978 final between the Netherlands and the hosts Argentina in Buenos Aires and although he was criticised by many journalists and football historians for what they perceived as a weak performance lacking authority, few matches in the history of the competition can have presented a tougher challenge.  Against a backcloth of political turmoil in a country that had suffered a military coup only two years earlier and where opponents of the regime were routinely kidnapped and tortured, or simply disappeared, this was Argentina’s chance to build prestige by winning the biggest sporting event in the world, outside the Olympics.  Rumours of subterfuge surrounded most of Argentina’s matches and when the final arrived the atmosphere in the stadium was as intimidating as anything Gonella would have experienced in his whole 13-year professional career.  The match began with an unprecedented delay, caused first by the Argentine team’s deliberate late arrival on the field.

Ferdinando II de’ Medici – Grand Duke of Tuscany

Technology fan who supported scientist Galileo

Inventor and patron of science Ferdinando II de’ Medici died on this day in 1670 in Florence.  Like his grandmother, the dowager Grand Duchess Christina, Ferdinando II was a loyal friend to Galileo and he welcomed the scientist back to Florence after the prison sentence imposed on him for ‘vehement suspicion of heresy’ was commuted to house arrest.  Ferdinando II was reputed to be obsessed with new technology and had hygrometers, barometers, thermometers and telescopes installed at his home in the Pitti Palace.  He has also been credited with the invention of the sealed glass thermometer in 1654.  Ferdinando II was born in 1610, the eldest son of Cosimo II de’ Medici and Maria Maddalena of Austria.  He became Grand Duke of Tuscany in 1621 when he was just 10 years old after the death of his father.  His mother, Maddalena, and paternal grandmother, Christina, acted as joint regents for him. Christina is said to have been the power behind the throne until her death in 1636.  Ferdinando II was patron and friend to Galileo, who dedicated his work, Dialogue Concerning the two Chief World Systems, to him.  Read more…

Girolamo Savonarola executed

Death of the friar who was to inspire best-selling novel by Tom Wolfe

The hellfire preacher Girolamo Savonarola was hanged and burned on this day in 1498 in Piazza della Signoria in Florence.  By sheer force of personality, Savonarola had convinced rich people to burn their worldly goods in spectacular bonfires in Florence during 1497, but within a year it was Savonarola’s burning corpse that the crowds turned out to see.  Savonarola had become famous for his outspoken sermons against vice and corruption in the Catholic Church in Italy and he encouraged wealthy people to burn their valuable goods, paintings and books in what have become known as ‘bonfires of the vanities.’  This phrase inspired Tom Wolfe to write The Bonfire of the Vanities, a novel about ambition and politics in 1980s New York.  Savonarola was born in 1452 in Ferrara. He became a Dominican friar and entered the convent of Saint Mark in Florence in 1482. He began preaching against corruption and vice and prophesied that a leader would arrive from the north to punish Italy and reform the church.  When Emperor Charles VIII invaded from the north many people thought Savonarola’s prediction was being fulfilled.  Read more…

Giuseppe Parini – writer

Satirist avenged bad treatment though his poetry

Poet and satirist Giuseppe Parini was born on this day in 1729 in Bosisio in Lombardy.  A writer associated with the Age of Enlightenment in Europe, he is remembered for his series of Horatian odes and for Il giorno - The Day - a satirical poem in four books about the selfishness and superficiality of the aristocracy in Milan.  The son of a silk trader, Parini was sent to Milan to study under the religious order, the Barnabites. In 1752 his first volume of verse introduced him to literary circles and the following year he joined the Milanese Accademia dei Trasformati - Academy of the Transformed - which was located at the Palazzo Imbonati in the Porta Nuova district.  He was ordained a priest in 1754 - a condition of a legacy made to him by a great aunt - and entered the household of Duke Gabrio Serbelloni at Tremezzo on Lake Como to be tutor to his eldest son.  Parini was unhappy there and felt he was badly treated, but he twice got his revenge on his employer through his writing. In 1757 he wrote his Dialogo sopra la nobilità, a discussion between the corpse of a nobleman and the corpse of a poet about the true nature of nobility.   Read more…

Trevi Fountain inaugurated

Famous fountain now helps raise money for the poor

Rome’s iconic Trevi Fountain - Fontana di Trevi - was officially opened by Pope Clement XIII on this day in 1762.  Standing at more than 26m (85ft) high and 49m (161ft) wide it is the largest Baroque fountain in Rome and probably the most famous fountain in the world.  It has featured in films such as La Dolce Vita and Three Coins in the Fountain.  For more than 400 years a fountain served Rome at the junction of three roads, tre vie, using water from one of Ancient Rome’s aqueducts.  In 1629 Pope Urban VIII asked Gian Lorenzo Bernini to draw up possible renovations but the project was abandoned when the pope died.  In 1730 Pope Clement XII organised a contest to design a new fountain. The Florentine Alessandro Galilei originally won but there was such an outcry in Rome that the commission was eventually awarded to a Roman, Nicola Salvi.  Work on the fountain began in 1732 but Salvi died in 1751 when it was only half finished. Made from Travertine stone quarried in Tivoli near Rome, the fountain was completed by Giuseppe Pannini, with Oceanus (god of all water), designed by Pietro Bracci, set in the central niche.  Read more…

José João Altafini - footballer who made history

Forward tamed Eusebio to give Italy first European Cup

Supporters of AC Milan took to the streets to celebrate on this day in 1963 after José João Altafini's goals secured an historic victory in the European Cup.  Milan beat Benfica at Wembley Stadium in London to become the first Italian team to win the trophy.  Until then the European Cup had been dominated by Real Madrid, who were champions for five years in a row after the competition was launched in 1955-56, with the great Eusebio's Benfica winning in 1961 and 1962.  At half-time at Wembley in 1963, Milan looked set to provide another near-miss story for Italy, trailing to a Eusebio goal as Benfica closed on a third successive title.  The rossoneri had lost to Real Madrid five years earlier, 12 months after the Spanish giants brushed aside Fiorentina in the final.  But 24-year-old Altafini, who became one of Serie A’s most prolific all-time goalscorers, refused to be cowed.  He netted in the 58th and 66th minutes, sparking joyous scenes in Milan and starting a period of European dominance for the city, with AC’s rivals Internazionale winning the next two tournaments.  The Milan team that night in London boasted two future Italy managers in Cesare Maldini and Giovanni Trapattoni, as well as the great Gianni Rivera, but Altafini was the star.  Read more…

Giulia Grisi - operatic soprano

Officer’s daughter became a star on three continents

The opera singer Giulia Grisi, one of the leading sopranos of the 19th century, was born on this day in 1811 in Milan.  Renowned for the smooth sweetness of her voice, Grisi sang to full houses in Europe, the United States and South America during a career spanning 30 years in which composers such as Vincenzo Bellini and Gaetano Donizetti created roles especially for her.  These included Elvira in Bellini’s final opera, I puritani, in which Grisi appeared alongside the great tenor Giovanni Battista Rubini, the bass Luigi Lablache and the baritone Antonio Tamburini when the work premiered in Paris in 1835.  The opera was such a success that whenever the four singers performed together subsequently they were known as the “Puritani quartet”.  Grisi was also the first soprano cast in the role of Adalgisa in Bellini’s Norma in Milan in 1831, playing opposite Giuditta Pasta in the title role.  Donizetti wrote the parts of Norina and Ernesto in his 1843 work Don Pasquale for Grisi and her future husband, the tenor Giovanni Matteo De Candia, usually known by his stage name of Giovanni Mario. Lablache and Tamburini again starred with her in the Paris premiere.  Read more…

Propaganda Due suspects named

Italy horrified as list reveals alleged members of ‘secret state’ 

Ordinary Italians were stunned and the country’s elite rocked to the core on this day in 1981 when a list was made public of alleged members of Propaganda Due, a secret Masonic lodge which sought to run the country as a ‘state within the state’.  A staggering 962 names were on the list, including 44 members of parliament, three of whom were cabinet ministers, 49 bankers, numerous industrialists, a number of newspaper editors and other high-profile journalists, the heads of all three of Italy’s secret services and more than 200 military and police officers, including 12 generals of the Carabinieri, five of the Guardia di Finanza, 22 of the army and four from the air force.  The existence of the illegal, underground lodge, known as P2 had been rumoured for several years but there had been little concrete evidence until magistrates investigating the collapse of the Banco Ambrosiano in Milan raided the home in Tuscany of Licio Gelli, the former Fascist financier who turned out to be the Grandmaster.  The list of alleged members, which was made public by Prime Minister Arnaldo Forlani on the advice of the prosecuting team, was found among paperwork seized in the raid.  Read more…

Pandolfo Petrucci – ruler of Siena

Ruthless tyrant who encouraged art

Pandolfo Petrucci, who during his time ruling Siena was one of the most powerful men in Italy, died on this day in 1512 in San Quirico d’Orcia in Tuscany.  Although he had been a tyrannical ruler, Petrucci had also done a great deal to increase the artistic splendour of his native city.  Petrucci was born into an aristocratic family in Siena in 1452. He had to go into exile in 1483 for being a member of the Noveschi political faction, which had fallen out of favour with the rulers of Siena.  After he returned to Siena in 1487, he began to take advantage of the struggles between the different political factions.  He married Aurelia Borghese, who was the daughter of Niccolò Borghese, an important figure in Siena at the time. After entering public office himself, Petrucci acquired so much authority and wealth that he became the ruling despot of Siena with the title of signore - lord.  His rapid rise to power alienated his father-in-law, who conspired with other influential citizens in Siena to assassinate him. However, Petrucci uncovered the plot and in 1500 had Borghese murdered. This act terrified his other enemies, which left Petrucci in complete control.  Read more…

Michelangelo’s Pietà damaged

Work of art deliberately vandalised

Michelangelo’s beautiful Pietà, a marble sculpture of the Virgin Mary with the dead body of Jesus lying across her knees, was damaged by a man wielding a hammer on this day in 1972 in Rome.  A mentally disturbed man walked into St Peter’s Basilica and attacked the sculpture in an act of deliberate vandalism.  He struck it 15 times, removing Mary’s arm at the elbow, knocking off a chunk of her nose and chipping one of her eyelids.  Some of the pieces of marble that flew off were taken by some of the people who were in the church at the time and Mary’s nose had to be reconstructed from a block cut out of her back.  The man who carried out the attack was said to be suffering from a delusion that he was Jesus Christ risen from the dead. He was not charged with any crime but spent two years in a psychiatric hospital.  After the restoration work was completed the sculpture was returned to its place in St Peter’s, just to the right of the entrance, and it is now protected by a bulletproof acrylic glass panel.  Michelangelo carved this sculpture from a single piece of Carrara marble in 1499 when he was only 24 and it is the only work he ever signed.  Read more…

Angelo Bruno - Mafia boss

Sicilian head of Philadelphia mob known as 'the Gentle Don'

Angelo Bruno, a mobster who ran the Philadelphia Mafia for two decades, was born Angelo Annaloro in Villalba, in the province of Caltanissetta, in Sicily, on this day in 1910.  Bruno was known as “the Gentle Don” because he preferred to solve problems and consolidate his power through non-violent means, such as bribery, and commissioned murders only as a last resort.  The son of a grocer, he emigrated to the United States in his teens and settled in Philadelphia. He became a close associate of New York crime family boss Carlo Gambino. Bruno dropped the name Annaloro and replaced it with his paternal grandmother's maiden name, Bruno.  Bruno’s dislike of violence was not driven by any compassion for his fellow man.  During his early days in Philadelphia, he worked for a series of bosses and did not shirk the tasks he had to perform in order to rise through the ranks, which included carrying out killings himself.  But in 1959, when he succeeded Joseph Ida as boss of the Philadelphia crime family, he decided it was in his interests and those of his criminal organisation to operate in a way that avoided attracting unwanted attention.  Read more…
