Giovanni Battista Beccaria - physicist and mathematician

Monk who explained how lightning conductors work

Beccaria was Professor of Physics
at the University of Turin

The physicist, mathematician and Piarist monk Giovanni Battista Beccaria, whose work with electricity confirmed and expanded upon the discoveries of the American polymath and Founding Father Benjamin Franklin, died in Turin on this day in 1781.

At the age of 64 he had been ill and in pain for some years but was working right up to his death on a treatise on meteors.

For much of his life, Beccaria had been occupied in the study of electricity with particular focus on the discoveries made by Franklin, with whom he corresponded regularly.

He successfully explained such things as the workings of the Leyden Jar and the Franklin square, two devices in which static electricity could be captured and stored, and why pointed objects could discharge electrified objects at a distance.

He was also able to explain why lightning rods, or lightning conductors, protect a building by providing a path along which electricity generated in the air in the form of lightning can be directed safely to earth. 

Beccaria wrote and published a complete treatise on Franklin’s electrical theory, called Dell’ Elettricismo naturale ed artificiale (On Natural and Artificial Electricity) in 1753.

Born in Mondovì, a town in Piedmont about 80km (50 miles) south of Turin in the province of Cuneo, in October, 1716, Beccaria entered the religious Order of the Pious Schools or Piarists at the age of 16. 

The Piarists had been founded in 1617 by Spanish priest Joseph Calasanz. It is the oldest religious order in the world dedicated to education.  After studying under the order, he taught grammar, rhetoric and mathematics. 

Benjamin Franklin, with whom
Beccaria often corresponded

He studied mathematics with such success that the order appointed him professor of experimental physics, first in the Scuole Pie of Palermo and then in Rome. 

Beccaria acquired a reputation as an effective teacher but found himself at the centre of controversy in 1748, when he was appointed by royal authority as Professor of Physics at the University of Turin. This was a coveted position and Beccaria was subjected to complaints from rivals that he was not sufficiently qualified for the role. 

In response, his sponsors came up with an idea to silence his critics. They had heard about the work of the French physicist, Thomas-François Dalibard, whose experiment at Marly-la-Ville, north of Paris, had demonstrated that lightning was a form of electricity, and urged Beccaria to make this new field his own area of expertise.

Beccaria followed their advice and set about writing and publishing a complete treatise on the electrical theory of Benjamin Franklin, news of whose work with electricity in the United States had reached Europe in 1751. Beccaria’s Dell’ Elettricismo naturale ed artificiale was published only two years later. 

Devoting himself to research on atmospheric electricity, Beccaria made use of kites, rockets, and iron wire in conducting his experiments. 

Using an early electroscope developed by the English physicist William Henley, Beccaria noted that, in broken or stormy weather, positive and negative electrification were detected, whereas in calm, serene weather, positive dominated.  He attributed the forked character of lightning to the resistance of the air and theorised that the spontaneous rupturing of the shoes worn by a man struck by a lightning bolt was the result of the "moisture of the feet flying into vapour".

Beccaria's treatise

Beccaria was also among the first to recognize and clearly state that the electrical charge on a conductor is confined to the surface and endorse Franklin’s views about the preventive and protective functions of lightning conductors. He was the first Italian to extract sparks from a conductor pointed to the sky.

His work confirmed the American’s finding that pointed rods could discharge electricity in the air, which eventually led to such rods being attached to tall buildings for the protection in an electrical storm of individuals on the ground. The King of Sardinia, Charles Emmanuel III, was so impressed that he asked Beccaria to install a lightning rod on the Royal Palace, 

In 1755, Beccaria was elected Fellow of the Royal Society of London. His work Dell'elettricismo artificiale e naturale was translated into English in 1778. Franklin described the treatise as “one of the best pieces on the subject in any language.”

Piazza Maggiore, the main square of the historic
Piedmont town of Mondovì, near Cuneo

Travel tip:

The historic town - and ancient city - of Mondovì is located in the Monregalese Hills at the foot of the southern Alps, where the Piedmont and Liguria regions meet. It is built on two levels, the upper being divided into several rioni (ancient quarters). The lower town developed from the 18th century when railway connections saw industries emerge. A funicular railway links the Breo quarter with Piazza, the oldest part of the town. Although the origins of Mondovì date back to the Roman Empire, it flourished during the Middle Ages, occupying a strategic position at the intersection of trade routes between Piedmont and the Mediterranean coast.  Piazza was founded around 1198 by the inhabitants of three hamlets, who joined forces to protect their community from outside threats. Nonetheless, the town was seized by the Bishops of Asti, followed by Charles I of Anjou, the Angevins, the Visconti, the Marquisate of Montferrat, the Acaja and, from 1418, the House of Savoy, who would leave an indelible mark on the character and architecture of the town, fortifying its walls and constructing buildings that still stand today.  In the mid-16th century, when it was occupied by France, Mondovì was the largest city in Piedmont and the seat of the region’s first university.

Cuneo's elegant Piazza Galimberti is one of the
largest squares in the whole of Italy

Travel tip:

The city of Cuneo, which developed at the confluence of the Stura and Gesso rivers about 28km (17 miles) west of Mondovì, is set out in a grid system with an elegant central square, Piazza Galimberti, one of the largest squares in Italy, after Piazza del Plebiscito in Naples. Surrounded by neo-classical buildings, it has a large statue of Giuseppe Barbaroux, the author of the Albertine Statute that formed the constitution of the Kingdom of Sardinia-Piedmont in 1848. The square is named after Duccio Galimberti, one of the heroes of the Italian resistance in the Second World War.   Cuneo had been acquired by the Duchy of Savoy in 1382 and remained an important stronghold of the Savoy state for many centuries.  Cuneo is the home of a chocolate confection called Cuneesi al rhum - small meringues with dark chocolate coating and a rum-based chocolate filling. They were the creation of Andrea Arione, whose bar and pasticceria, Caffè Arione, is still located in Piazza Galimberti.

Giovanni Giolitti – Prime Minister

Long-lasting Liberal politician made important social reforms

Giovanni Giolitti was one of
Europe's main liberal reformers

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.

He made progressive social reforms that improved the living standards of ordinary Italians and he nationalised the telephone and railway operators.

Giolitti’s father, Giovenale Giolitti, had worked in the avvocatura dei poveri, assisting poor people in both civil and criminal cases. He died in 1843, the year after his son, Giovanni, was born. The family moved to live in his mother’s family home in Turin, where she taught him to read and write.

Giolitti earned a degree in law
from the University of Turin

Giolitti was educated in Turin and went to the University of Turin at the age of 16, where he earned a law degree after three years.

His uncle was a friend of Michelangelo Castelli, the secretary of Camillo Benso di Cavour - the united Italy's first prime minister - but Giolitti was not interested in the Risorgimento and did not fight in the Italian Second War of Independence, choosing instead to work in public administration.

At the 1882 Italian general election, Giolitti was elected to the Chamber of Deputies. In 1889 he was selected by Francesco Crispi as the new Minister of Treasury and Finance, but he later resigned because he did not agree with Crispi’s colonial policy.

After the fall of a new government led by Antonio Starabba di Rudini, Giolitti was asked by King Umberto I to form a new cabinet.

He resigned after a series of problems and scandals and was impeached for abuse of power, but this allegation was later quashed. He was once again appointed prime minister by King Victor Emmanuel III, but he had to resign in 1905 after losing the support of the Socialists.

When the next prime minister, Sidney Sonnino, lost his majority in 1906, Giolitti became prime minister again. He introduced laws to protect women and child workers and passed a law to provide workers with a weekly day of rest.

Giolitti was re-elected in 1909 but soon had to resign again, afterwards supporting the new head of government, Luigi Luzzatti, while remaining the real power behind the scenes.

In 1911, Luzzati resigned from office and Victor Emmanuel III again gave Giolitti the task of forming a new cabinet.

In 1912, Giolitti got Parliament to approve an electoral reform bill that expanded the electorate from three million to eight and a half million voters. This is thought to have hastened the end of the Giolitti era. The Radicals brought down Giolitti’s coalition in 1914 and he resigned.  

He became prime minister again in 1920, supported by Mussolini’s Fascist party, but he had to step down in 1921. By 1925 he had become completely opposed to the Fascist party and refused to join. He died in 1928 in Cavour in Piedmont and his last words to the priest were that he could not sing the official anthem of the Fascist regime.

A section of the Piazza Maggiore, with its
frescoed Baroque architecture

Travel tip: 

Mondovì is a beautiful town of some 22,000 inhabitants situated in Italy’s Piedmont region at the foot of the southern Alps, close to the border between Piedmont and Liguria.  Like much of the area in which it sits, the town is rich in mediaeval frescoes and Baroque architecture from the 17th and 18th centuries, many of the buildings designed by local architect Francesco Gallo.  The town is in two sections: the lower town called Breo, which grew up alongside the Ellero river, is linked to the upper town of Piazza by a funicular railway.  Mondovì Piazza, the old part of the city founded around 1198, has the two-level Piazza Maggiore at its heart, surrounded by beautiful porticoed buildings such as Palazzo dei Bressani and the Governor’s Palace.  Mondovì was one of the most important towns during the Savoy era, with an ancient university and a printing press that produced, in 1472, the first book printed in Piedmont with modern typography.  The town’s printing museum - the Museo della Stampa - can be found in the 17th century Palazzo delle Orfane. 

Cavour is dominated by the giant Rocca di 
Cavour, which looms over the town

Travel tip: 

Cavour is a small town of around 5,500 residents in Piedmont, situated about 40km (25 miles) southeast of Turin, built at the foot of the Rocca di Cavour, an isolated mass of granite rising from otherwise flat terrain. On top of the Rocca, once the site of a Roman village, are some mediaeval remains. The town gave its name to the Benso family of Chieri, of whom the most famous member was Camillo Benso, Count of Cavour, the statesman who was a driving force in the Risorgimento and was appointed the first prime minister of the united Italy in 1861.  The Rocca di Cavour has been a protected natural park since 1995.
