Ulisse Dini – mathematician and politician

Patriotic professor was proud to serve the new Kingdom of Italy

Ulisse Dini went to Paris to further
his mathematical education

The mathematician Ulisse Dini, who wrote many books and papers based on his research and came up with original theories that advanced the knowledge in his field, died on this day in 1918 in Pisa.

Now regarded as one of the 19th century's most important contributors to the evolution of mathematics, Dini was also active as a politician and was elected to Pisa city council before becoming a member of the parliament of the new Kingdom of Italy. 

His political views were shaped by the changing landscape of Italy while he was growing up, as the country moved closer to unification, and he was always keen to help his local area and his country.

Originally intending to become a teacher, Dini, who was born in Pisa in 1845 when the city was part of the Grand Duchy of Tuscany, attended the Scuola Superiore in Pisa, a teachers’ college, where one of his teachers was the mathematician, Enrico Betti.

However, in 1865, Dini received a scholarship that enabled him to go to Paris to further his mathematical studies, where he was taught by the French mathematicians, Charles Hermite and Joseph Bertrand. He produced seven mathematical publications based on the research he was able to do while living in Paris.

The following year he was appointed by the University of Pisa to teach algebra and geodesy, the science of measuring and representing the geometry, gravity, and spatial orientation of the earth in temporally varying 3D. 

Dini succeeded Betti as professor for analysis and geometry at the university in 1871. He was rettore - rector - of Pisa University from 1888 until 1890, and of the Scuola Superiore in Pisa from 1908 until his death. One of his students at Pisa University was the Italian mathematician, Luigi Bianchi.

Enrico Betti was 
Dini's teacher

Professor Dini is particularly known for his contribution to the branch of mathematics known as real analysis, which studies the behaviours of real numbers, sequences and series of real numbers, and real functions. He collected his theories in his book, ‘Fondamenti per la teorica delle funzioni di variabili reali’, a collection of ideas that were entirely originated by himself. 

Despite his heavy academic workload, Dini had entered politics by the age of 25, when he was elected to the city council in Pisa.

When Dini was 13, the fight had begun to win back areas of the country from the Austrian occupying forces. Within a few years, forces representing the Kingdom of Sardinia had gained control of many areas in central Italy. Victor Emmanuel II of Sardinia later assumed the title of King of Italy, and Giuseppe Garibaldi and his 1000 volunteers set out to unify the country, starting by invading Sicily. With his forces, Garibaldi gradually moved northwards up the peninsula and this led to the official proclamation of the Kingdom of Italy in 1861.

Ulisse Dini is remembered by historians and writers as an upright, honest, and kind man, and for being devoted to the well-being of his city and country. He divided his time between teaching and research and public service, and in 1892 he became a senator in the Italian parliament. 

In the field of mathematical analysis, he is remembered for being the originator of Dini criterion and Implicit function theorem. He was considered one of the most important European mathematicians of the 19th century and he was elected as an honorary member of the London Mathematical Society.

After his death, Dini was buried in Pisa’s monumental cemetery, Campo Santo, on the northern edge of the Campo dei Miracoli. There is a statue commemorating his life in Via Ulisse Dini in the city’s historic centre. 

The 15th century Palazzo della Sapienza, built by
the Medici family, remains the heart of the university

Travel tip: 

The University of Pisa, founded in 1343, is one of the oldest in Italy and rivals Rome’s Sapienza University for the title of the country’s best. Various scholars place its origins in the 11th century, although those claims have never been verified. What is certain is that the papal seal “In Supremae dignitatis”, issued by Pope Clement VI on 3 September 1343, granted the Studium in Pisa the title of Studium Generale. At the outset in Pisa, lessons in Theology, Civil Law, Canon Law and Medicine were established. In its early years, the university struggled to survive at times, but investment from the Medici family in the 15th century saw the construction of the Palazzo della Sapienza, still the centre of the present-day university. Cosimo I de’ Medici instituted programmes to improve the quality of teaching and later Galileo Galilei, universally seen as the founder of modern science, was initially a student and then a teacher of Mathematics at the university. Today, Pisa has a student population of around 50,000, who give the city a vibrant cafe and bar scene.

The bronze statue of Ulisse 
Dini was finished in 1927

Travel tip: 

The bronze sculpture of Ulisse Dini in Via Ulisse Dini was created in 1927 by Leonardo Bistolfi, a sculptor from Casale Monferrato in Piedmont, whose work was praised for its likeness to the subject.  Via Ulisse Dini goes from Borgo Stretto to Piazza dei Cavalieri and Dini’s statue stands beside the Church of Santo Stefano dei Cavalieri. Once a stream flanked by wooden houses belonging to the city’s higher social classes, the street subsequently became a centre for forges and metalworkers’ workshops. Some of the stone arches lining the modern street date back to the 12th century.  Aside from the Campo dei Miracoli, the biggest attraction of which is the city’s world famous leaning bell tower, Pisa offers visitors a wealth of well-preserved Romanesque buildings, Gothic churches and Renaissance piazzas.

Enrico Mattei – industrialist and entrepreneur

Death in plane crash remains an unsolved mystery

Enrico Mattei, one of the most important figures in Italy’s post-War economic rebirth, was killed on this day in 1962 in a plane crash near the village of Bascapè in Lombardy.  Accompanied by a Time-Life journalist, William McHale, Mattei was returning to Milan from Catania in Sicily in a French-built four-seater Morane-Saulnier jet being flown by Irnerio Bertuzzi, a respected pilot who had flown many daring missions during the Second World War.  They were on their descent towards Milan Linate when the crash happened, less than 17km (10.5 miles) from the airport.  Mattei, a politically powerful industrialist, best known for turning round Italy’s seemingly unviable oil industry, was not short of enemies and after his death there was considerable speculation that it did not happen by accident.  A government-led investigation, overseen by the then Italian Defence Minister Giulio Andreotti, concluded that a storm was to blame for the crash, even though the pilot was highly experienced and very unlikely to have allowed bad weather to bring him down.  Questions about the initial inquiry’s findings led to a second inquiry being opened in 1966 but shelved without reaching a conclusion.  Read more…

Simone Moro - mountaineer

Bergamo climber with unique record

The mountaineer Simone Moro, who is the only climber whose list of achievements includes the first winter ascent of four of the so-called eight-thousanders, was born on this day in 1967 in the city of Bergamo in Lombardy.  The eight-thousanders are the 14 peaks on Earth that rise to more than 8,000m (26,247ft) above sea level. All are located in the Himalayan and Karakoram mountain ranges in Asia.  A veteran of 15 winter expeditions, he completed the winter ascent of Shisha Pangma (8,027m) in 2005, Makalu (8,485m) in 2009, Gasherbrum II (8,035m) in 2011 and Nanga Parbat (8,126m) in 2016.  He has scaled Everest (8,848m) four times, including the first solo south-north traverse in 2006. In total he has completed more than 50 expeditions, conquering peaks in Tien Shan, Pamir, Andes, Patagonia and Antarctica as well as the Himalayas and Karakoram.  Moro is also renowned for his courage and bravery. During his 2001 attempt on the Everest-Lhotse traverse, he abandoned his ascent at 8,000m and battled through the most dangerous conditions in darkness to save the life of British climber Tom Moores.  Read more…

Giovanni Giolitti – Prime Minister

Long-lasting Liberal politician made important social reforms

Giovanni Giolitti, who served as Prime Minister of Italy five times, was born on this day in 1842 in Mondovì in Piedmont.  A Liberal, he was the leading statesman in Italy between 1900 and 1914 and was responsible for the introduction of universal male suffrage in the country.  He was considered one of the main liberal reformers of late 19th and early 20th century Europe, along with George Clemenceau, who was twice prime minister of France, and David Lloyd George, who led the British government from 1916 to 1922.  Giolitti is the longest serving democratically elected prime minister in Italian history and the second longest serving premier after Benito Mussolini. He is considered one of the most important politicians in Italian history.  As a master of the political art of trasformismo, by making a flexible, centrist coalition that isolated the extremes of Left and Right in Italian politics after unification, he developed the national economy, which he saw as essential for producing wealth.  The period between 1901 and 1914, when he was Prime Minister and Minister of the Interior with only brief interruptions, is often referred to as the Giolitti era.  Read more…

Roberto Benigni - Oscar winner

How Life is Beautiful made Tuscan actor and director famous

Roberto Benigni, whose performance in the 1997 film Life is Beautiful won him an Oscar for Best Actor, was born on this day in 1952 in rural Tuscany, around 20km (12 miles) south of Arezzo.  The Academy Award, for which he beat off strong competition from Nick Nolte (Affliction) and Tom Hanks (Saving Private Ryan) among others, put him in the company of Anna Magnani (1955) and Sophia Loren (1961) as one of just three Italian winners of best actor or actress.  Benigni, who also directed Life is Beautiful, had won the Oscar for Best Foreign Language Film earlier in the awards ceremony, which delighted him so much he famously clambered on to the back of the seats of audience members in the row in front of his to lead the applause before stepping up to the stage to receive the award from Sophia Loren.  When Helen Hunt called out his name for Best Actor - the first since Loren to win the most coveted prize with a foreign language film - he began his acceptance speech by apologising for having "used up all my English", before proceeding to deliver another joyously emotional expression of gratitude.  Read more…

Niccolò Paganini - musician and composer

Extraordinary talent aroused bizarre suspicions

The musician and composer Niccolò Paganini, widely regarded as one of the greatest violinists of all time, was born on this day in 1782 in Genoa. Paganini’s ability was so far ahead of his contemporaries that to some observers it defied comprehension. He possessed unusually long fingers, a memory that enabled him to play entire pieces without the need for sheet music, and could play at up to 12 notes per second.  This, combined with his appearance - he was tall and thin, with hollow cheeks, pale skin and a fondness for dressing in black - as well as a habit of making wild, exaggerated movements as he played, gave rise to outlandish theories that he was possessed by the Devil, or even was the Devil himself. He also pursued a somewhat dissolute lifestyle, drinking heavily, gambling and taking advantage of his fame to engage in numerous affairs.  The suspicion of demonic associations stayed with him all his life to the extent that after his death at the age of 58 it was four years before his body was laid to rest because the Catholic Church would not give him a Christian burial, their reticence not helped by his refusal to accept the last rites.  Read more…

Book of the Day: The Prize: The Epic Quest for Oil, Money & Power, by Daniel Yergin

The definitive work on the subject of oil and a major contribution to understanding our century, The Prize is a book of extraordinary breadth, riveting excitement - and great importance.  The struggle for wealth and power that has surrounded oil for decades continues to shake the world economy, dictate the outcome of wars, and transform the destiny of men and nations. The Prize is as much a history of the 20th century as of the oil industry itself. The canvas of this history is enormous - from the drilling of the first well in Pennsylvania through two great world wars to the Iraqi invasion of Kuwait and Operation Desert Storm. The cast extends from wildcatters and rogues to oil tycoons, and from Winston Churchill and Ibn Saud to George Bush and Saddam Hussein.

Daniel Yergin is a respected writer and president of Cambridge Energy Research Associates, a company specialising in political risk and economic analysis. He advises ministers, politicians, CEOs and investors around the world.

Primo Carnera - boxer

Heavyweight’s career dogged by ‘fix’ rumours

The boxer Primo Carnera, who was world heavyweight champion between 1933 and 1934, was born on this day in 1906 in a village in Friuli-Venezia Giulia.  After launching his professional career in Paris in 1928, Carnera moved to the United States in 1930 and spent many years there, returning from time to time to Italy, where he had a house built for himself and his family, but not permanently until he was in declining health and decided he would like to spend his final years in his home country.  He won 89 of his 103 fights, 72 by a knockout, although there were suspicions that many of his fights were fixed by the New York mobsters who made up his management team, even including the victory over the American Jack Sharkey that earned him the world title.  Physically, he was a freak.  Said to have weighed 22lbs at birth he had grown to the size of an adult man by the time he was eight. By adulthood, he was a veritable giant, by Italian standards, standing 6ft 6ins tall when the average Italian man was 5ft 5ins.  His fighting weight was as high at times as 275lb (125kg).  He was born into a peasant family in the village of Sequals, around 45km (28 miles) west of Udine.  Read more…

Trieste becomes part of Italy

Fascinating city retains influences from past rulers

The beautiful seaport of Trieste officially became part of the Italian Republic on this day in 1954.  Trieste is now the capital of the Friuli-Venezia Giulia region, one of the most prosperous areas of Italy.  The city lies towards the end of a narrow strip of land situated between the Adriatic Sea and Slovenia and it is also just 30km (19 miles) north of Croatia.  Trieste has been disputed territory for thousands of years and throughout its history has been influenced by its location at the crossroads of the Latin, Slavic and Germanic cultures.  It became part of the Roman Republic in 177 BC and was granted the status of a Roman colony by Julius Caesar in 51 BC.  In 788 Trieste was conquered by Charlemagne on behalf of the French but by the 13th century was being occupied by the Venetian Republic. Austria made the city part of the Habsburg domains in the 14th century but it was then conquered again by Venice. The Habsburgs recovered Trieste in the 16th century and made it an important port and a commercial hub.  Trieste fell into French hands during the time of Napoleon but then became part of Austrian territory again.  Read more…

Domenico Scarlatti - composer

Neapolitan famous for his 555 keyboard sonatas

The composer Giuseppe Domenico Scarlatti, known as Domenico Scarlatti, was born in Naples on this day in 1685.  Born in the same year as Johann Sebastian Bach and George Frideric Handel, Scarlatti was the sixth of 10 children fathered by the composer Alessandro Scarlatti.  Like his father, Domenico composed in a variety of musical styles, making the transition in his lifetime from Baroque to traditional Classical. Today, he is known mainly for his 555 keyboard sonatas, which expanded the musical possibilities of the harpsichord.  Although he began his career in Naples, Scarlatti spent a large part of his life in the service of the Portuguese and Spanish royal families. In fact, he died in Madrid in 1757.  Early in 1701, at the age of just 15, Scarlatti was appointed as composer and organist at the royal chapel in Naples. At 17, his first operas, L’Ottavia restituita al trono and Il giustino, were produced there.  In 1705 his father sent him to Venice, reputedly to study with the composer Francesco Gasparini, although nothing is known with certainty about his life there. It is thought he may have met a young Irishman, Thomas Roseingrave, who later described Scarlatti’s advances in harpsichord music to the English musicologist Charles Burney.  Read more…

Trilussa - poet and journalist

Writer used humour and irony in social commentary

The Roman poet who went under the name Trilussa was born on this day in 1871.  The writer, best known for his works in Romanesco dialect, was actually christened Carlo Alberto Camillo Mariano Salustri. His pseudonym was an anagram of his last name.  He was inspired to take up poetry by his admiration for Giuseppe Gioachino Belli, who satirised life in 19th century Rome in his sonnets, which were also written in Roman dialect.  Born in a house in Via del Babuino, near the Spanish Steps, Carlo was the son of a waiter originally from Albano Laziale in the Castelli Romani area around Lago Albano south of Rome. His mother, Carlotta, was a seamstress born in Bologna.  His early years were marred by tragedy. He lost both a sister and his father before he had reached four years old.  After living for a short time in Via Ripetta, close to the Tiber river, his family were offered accommodation in a palazzo in Piazza di Pietra, a square midway between the Pantheon and the Trevi Fountain.  The palazzo was owned by Carlo’s Godfather, the Marquis Ermenegildo del Cinque, who had been introduced to the family by Professor Filippo Chiappini, a disciple of Belli who for a while was Trilussa’s tutor.  Read more…

Giuditta Pasta – soprano

The first singer to perform the roles of Anna Bolena and Norma

Singer Giuditta Pasta, whose voice was so beautiful Gaetano Donizetti wrote the role of Anna Bolena especially for her, was born on this day in 1797 in Saronno in Lombardy.  Her mezzo-soprano voice was much written about by 19th century opera reviewers and in modern times her performance style has been compared with that of Maria Callas.  Indeed, Vincenzo Bellini’s opera Norma, which Callas would turn into her signature role, was actually written for Pasta in 1831.  Pasta was born Giuditta Negri, the daughter of a Jewish soldier. She studied singing in Milan and made her operatic debut there in 1816.  Later that year she performed at the Theatre Italien in Paris as Donna Elvira in Don Giovanni, but it was not until 1821 that her talent was fully recognised when she appeared in Paris as Desdemona in Gioachino Rossini’s Otello.  Giuditta married another singer, Giuseppe Pasta, in 1816 and as well as being her regular leading man he handled her business affairs and identified likely roles and composers who might wish to work with her.  Read more…

Primo Carnera: The Life and Career of the Heavyweight Boxing Champion, by Joseph S Page

At over six and a half feet tall and nearly 300 pounds, heavyweight champion Primo Carnera was a giant for his times, but today "the Ambling Alp" is too often written off as an unskilled oaf and a product of the mob dealings that plagued boxing during the 1930s. He may not have been a natural in the ring, but he worked as hard as any boxer to learn his craft, to be in top condition, and he repeatedly showed that he was tougher than nails. Primo Carnera: The Life and Career of the Heavyweight Boxing Champion details Carnera's early life and boxing career, his success as a fighter as well as accusations of fight fixing, his strengths and limitations in the ring, and his later career as a wrestler.

Joseph S Page is an American writer who is also the author of Pro Football Championships Before the Super Bowl: A Year-by-Year History, 1926–1965.

Camillo Sivori – virtuoso violinist

Paganini’s successor was also a talented composer

Ernesto Camillo Sivori, a virtuoso violinist and composer, was born on this day in 1815 in Genoa.  Remembered as the only pupil of the great virtuoso violinist Niccolò Paganini, Sivori began his career as a travelling virtuoso at the age of 12, having by then also studied with other violin teachers.  He was acclaimed as ‘Paganini reincarnated’, or even, ‘Paganini without the flaws’, by music critics during a lengthy tour of Europe that he made between 1841 and 1845.  During his travels he met some of the best-known composers of the day, such as Mendelssohn, Schumann and Berlioz and he took part in hundreds of concerts.  After being compared to other celebrated violinists, his status as Paganini’s successor was confirmed, even though the great man had died in 1840 and was still remembered in the musical world.  Sivori had met Paganini, who was also from Genoa, when he was seven years old and had made such a favourable impression on him that Paganini gave him lessons between October 1822 and May 1823.  Paganini also wrote pieces of music for his pupil ‘to shape his spirit’ and even provided guitar accompaniment when Sivori performed these pieces privately.  Read more…

Evangelista Torricelli – inventor of the barometer

Physicist's name lives on in scientific terminology

The inventor of the barometer, Evangelista Torricelli, died on this day in 1647 in Florence at the age of just 39.  A disciple of Galileo, Torricelli made many mathematical and scientific advances during his short life and had an asteroid and a crater on the moon named after him.  Torricelli was born into a poor family from Faenza in the province of Ravenna.  He studied science under the Benedictine monk, Benedetto Castelli, a professor of Mathematics at the Collegio della Sapienza, now known as the Sapienza University of Rome, who had been a student of Galileo Galilei.  After Galileo’s death the Grand Duke Ferdinand II de’ Medici asked Torricelli to succeed Galileo as Chair of Mathematics at the University of Pisa.  Torricelli was also interested in optics and designed and built telescopes and microscopes.  His most important invention was the mercury barometer, which he produced after he had discovered the principle of the barometer while trying to find a solution to the limitations of the suction pump in forcing water upwards.  Scientific terms such as the Torricellian tube and Torricellian vacuum are named after the scientist, as is the torr, a unit of pressure in vacuum measurements.  Read more…

Carlo Gnocchi – military chaplain

Remembering a protector of the sick and the mutilated

Carlo Gnocchi, a brave priest who was chaplain to Italy’s alpine troops during the Second World War, was born on this day in 1902 in San Colombano al Lambro, near Lodi in Lombardy.  In recognition of his life, which was dedicated to easing the wounds of suffering and misery created by war, his birthday was made into his feast day when he was beatified by Pope Benedict XVI on October 25, 2009 in Milan.  Gnocchi was the youngest of three boys born to Henry and Clementine Gnocchi. His father died when he was five years old and his two brothers died of tuberculosis before he was 13.  He was ordained a priest in 1925 in the archdiocese of Milan and afterwards worked as a teacher.  When war broke out he joined up as a voluntary priest and departed first for the front line between Greece and Albania and then for the tragic campaign in Russia, which he miraculously survived, despite suffering from frostbite.  While he was chaplain to alpine troops in the war he helped Jews and Allied prisoners of war escape to Switzerland. During this time he was imprisoned for writing against Fascism.  Read more…

Book of the Day: Paganini: The 'Demonic' Virtuoso, by Mai Kawabata

Our inherited image of Nicolo Paganini as a 'demonic violinist' has never been analysed in depth. What really made him 'demonic'? This book investigates the legend of Paganini. Separating fact from fiction, it explains how the virtuoso violinist challenged the very notion of what it meant to be a musician. Mai Kawabata considers Paganini's performance innovations, violin techniques and musical ethos in the light of contemporary attitudes towards music and the supernatural, gender, sexuality, violence, heroism and masculinity as well as conceptions of power. The many perceptions of Paganini as demonic - Faust, magician, devil, rake/libertine, Napoleon - were interrelated but not equivalent. A swirl of cultural factors coalesced in the performer to create that phenomenon of Romanticism, a larger-than-life Gothic villain. In The 'Demonic' Virtuoso, Kawabata shows how the idea of virtuosity spiralled out of control, acquiring a potent, overwhelmingly negative aura in the process, as the mythology surrounding Paganini outlived and outgrew the man to monstrous proportions. An appendix brings together late 19th-century British press and literature coverage of Paganini that contributed to the developing myth surrounding the now famous composer and performer. 

Mai Kawabata is Lecturer in Music at the University of East Anglia and a professional violinist.
