Francesco Laparelli - architect and military engineer

Italian who designed Valletta, the fortified capital of Malta

Francesco Laparelli found himself
in demand as a military architect

The architect Francesco Laparelli da Cortona, who worked as assistant to Michelangelo Buonarroti at St Peter’s Basilica in Rome but is chiefly renowned for the design of Valletta, the fortified capital city of Malta, was born on this day in 1521 in the hilltop city of Cortona in what is now Tuscany.

Laparelli designed the campanile - bell tower - for Cortona’s duomo but turned his talents towards military engineering after serving as an officer under Cosimo de’ Medici during the battle for control of the Republic of Siena in the 1550s.

He went on to serve on Cortona’s city council and worked with other engineers on the Fortezza del Girifalco above the city. The cost of the fortress and other work on the city walls eventually bankrupted the city but Laparelli’s reputation was established.

He was summoned to Rome by Pope Pius IV in 1560  on the recommendation of Gabrio Serbelloni, the pope’s cousin and a condottiero with whom Laparelli had worked in Cortona.

Pius IV commissioned him to restore the fortifications at Civitavecchia, Rome’s main port, to build defences for the mouth of the Tiber river and to direct the strengthening of fortifications around the Vatican and the new suburb of Borgo Pio.

In 1565 he completed the reinforcement of the cylindrical Castel Sant'Angelo, now a familiar Rome landmark, and collaborated with Michelangelo on the huge dome of St Peter's Basilica, with particular focus on ensuring it was a stable structure.

Modern Valletta, capital of Malta, still resembles
the fortress-city that was planned by Laparelli

Laparelli was keen to take on further architectural projects in the capital but later in 1565 was asked by Pope Pius V to go to Malta, where the Knights of St John had finally defied a long siege of the island by the Ottoman Turks, who wanted it as a base from which to attack Italy, but at a cost of considerable destruction to the principal forts at Birgu, Senglea and St Elmo.

The Grand Knight, Jean Parisot de la Valette, favoured rebuilding the existing defences but Laparelli calculated that it would need 4,000 labourers working 24 hours a day just to make basic repairs and proposed that a new fortification on the Sciberras Peninsula could be built at a much cheaper cost. Such a fortification, he said, would enable Malta to be defended against any new incursion by the Turks with just 5,000 soldiers, far fewer than the 12,000 soldiers and 200 horses previously required to protect the island.

Laparelli’s design was for a city built on a grid plan with wide, straight streets, surrounded by ramparts and with the fort of St Elmo rebuilt at the tip of the peninsula. A ditch, later renamed the Ġnien Laparelli as a tribute to him, was added to protect the landward end of the peninsula.

assistant, Girolamo Cassar, in Valletta

He left Malta in 1569 to help in the papal naval war against the Turks, at which point the major construction work on the city, to be called Valletta, was still to begin.

Born into one of Cortona’s wealthiest and most illustrious families, Laparelli would have one day hoped to return to his home city, where he still owned considerable land and estates, but met with an early death in Crete, where he was staying when he contracted plague at the age of 49 in 1570.

He was unable to see his designs reach fruition in Valletta, where his work was continued by his Maltese assistant, Girolamo Cassar. Both he and Cassar are commemorated with a monument between Valletta’s Parliament House and the ruins of its old Royal Opera House, sculpted by John Grima and unveiled in 2016.

city of Cortona, his place of birth

Travel tip:

Cortona, Laparelli’s home town, was founded by the Etruscans, making it one of the oldest cities in Tuscany. Its Etruscan Academy Museum displays a vast collection of bronze, ceramic and funerary items reflecting the town’s past. The museum also offers access to an archaeological park that includes city fortifications and stretches of Roman roads. Outside the museum, the houses in Via Janelli are some of the oldest houses still surviving in Italy. Powerful during the mediaeval period, Cortona was defeated by Naples in 1409 and then sold to Florence.  Characterised by its steep narrow streets, Cortona’s hilltop location - it has an elevation of 600 metres (2,000 ft) - offers sweeping views of the Valdichiana, including Lago Trasimeno, where Hannibal ambushed the Roman army in 217 BC during the Second Punic War.

Castel Sant'Angelo, which Laparelli reinforced before
leaving for Malta, is a well-known Rome landmark

Travel tip:

Castel Sant’Angelo was originally built as a mausoleum for the Roman Emperor Hadrian and his family on the right bank of the Tiber between 134 and 139 AD. There is a legend that the Archangel Michael appeared on top of the mausoleum, sheathing his sword as a sign of the end of the plague of 590, which is how the castle acquired its present name. Pope Nicolas III commissioned a covered fortified corridor, the Passetto, to link it to the Vatican and Pope Clement VII was able to use it to escape from the Vatican during the siege of Rome by Charles V’s troops in 1527. Castel Sant’Angelo was used as the setting for the third act of Giacomo Puccini’s 1900 opera Tosca, during which the heroine leaps to her death from the ramparts.

Eugenio Barsanti - engineer

Created the first working internal combustion engine

A model of the Barsanti-Matteucci engine
pictured on display at a museum in Milan

The engineer Eugenio Barsanti, whose internal combustion engine was the first working example of the technology known to have been produced, was born on this day in 1821 in Pietrasanta, a town in northern Tuscany.

The Belgian-French engineer Étienne Lenoir and the German Nicolaus Otto are credited with the first commercially successful internal combustion engines, but Barsanti’s machine, which he developed with partner Felice Matteucci, was unveiled in 1853 - six years before Lenoir’s and eight years ahead of Otto’s.

Barsanti might have achieved commercial success himself but shortly after reaching an agreement with a company in Belgium to produce his machine on a commercial scale he contracted typhoid fever, from which he never recovered.

A rather sickly child, known by his parents as Nicolò, Barsanti took the name Father Eugenio after entering the novitiate of the Piarists, the oldest Catholic religious order dedicated to education, where was ordained as a priest.

He took a teaching position at Collegio San Michele in Volterra. It was there, while lecturing on the explosive energy created by mixing hydrogen and air that he realised the potential of using combustible gases to lift the pistons in a motor.

He developed the idea further after meeting Matteucci, an engineer, while teaching at an institute in Florence. 

A postage stamp issued to mark the 150th
anniversary of the engine's invention

After exhibiting their first engine at the prestigious Accademia dei Georgofili in Florence to much excitement, Barsanti and Matteucci travelled to London to obtain a patent. 

By 1856, Barsanti and Matteucci had developed a two-cylinder five horsepower motor and two years later built a two-piston engine designed to provide a source of energy to drive machinery in factories and workshops.

The Barsanti-Matteucci engine was quicker and more efficient than the one developed by Lenoir and won a silver medal from the Institute of Science of Lombardy. They believed it could also be used in the propulsion of ships as an alternative to steam.

After the prototype of their engine was built in Milan, the two were all set to go into mass production at a plant near Liège in Belgium owned by the English industrialist John Cockerill when Barsanti fell ill with typhoid fever. He died on April 18, 1864.

After his partner’s death, Matteucci found himself unsuited to the demands of running a commercial business and failed to secure the contracts necessary to make mass production viable. He returned to his previous work in hydraulics. 

Nicolaus Otto, on the other hand, had a background in business, giving him an edge not only in marketing skills but in the contacts he could approach for investment. He was the first to enjoy significant commercial success producing internal combustion engines and tends to be credited with its invention.

Barsanti's ashes are buried at the 
Basilica of Santa Croce in Florence

Matteucci’s arguments that Otto’s engine was clearly similar to his and Barsanti’s were largely ignored. Nonetheless, many of the documents relating to the original patents he and Barsanti obtained are preserved in the Museo Galileo in Florence, while Barsanti’s achievements are acknowledged in Italy, where a postage stamp was issued to commemorate the 150th anniversary of the Barsanti-Matteucci engine.

In 1954, Barsanti's ashes were moved from the Church of San Giovannino degli Scolopi, the small, Piarist church in Florence, to the Basilica of Santa Croce, to rest alongside the remains of such illustrious Italians as Michelangelo, Galileo, Machiavelli, the poet Ugo Foscolo and the composer Gioachino Rossini among many others.

Copies of Barsanti’s engines can be seen at the Osservatorio Ximeniano in Florence and the Leonardo da Vinci National Museum of Science and Technology in Milan.

The wide, sandy beach at Marina di Pietrasanta
is 5km long and attracts thousands of visitors

Travel tip:

Pietrasanta, just north of Viareggio in the province of Lucca in Tuscany, still has part of its Roman wall, although as a mediaeval town it was not founded until 1255, expanding around the Rocca di Sala fortress of the Lombards. Its Duomo - the Collegiate Church of San Martino - dates back to the 13th century. Pietrasanta grew in importance in the 15th century due to its marble, the beauty of which was first recognised by the sculptor, Michelangelo, to be followed in later years by such artists as Fernando Botero, Joan Miró, Henry Moore, and Damien Hirst. The town declined during the 17th and 18th centuries, partly due to malaria, but underwent reconstruction in the 19th century. It has a pleasant central square, while the seaside resort of Marina di Pietrasanta is just 3km (1.9 miles) away.  Part of the Versilia coastline, Marina di Pietrasanta boasts some of the area's best beaches, stretching for 5km (3 miles).

The waterfront at Viareggio is notable for its many
examples of Liberty-style architecture

Travel tip:

Viareggio, which can be found just 13km (8 miles) south of Pietrasanta, is a popular resort also known for its excellent sandy beaches and for its carnival, a month-long event dating back to 1873 that runs from February through to March and features parades of giant papier-mache floats designed to represent well-known public figures. The Tuscan resort is also notable for its beautiful Liberty-style architecture, much of it built in its heyday in the late 19th and early 20th century, many examples of which thankfully survived heavy bombing in World War Two when the town was a target because of its shipbuilding industry.  The body of the English poet Shelley, who drowned at sea, was washed up on a beach near the resort in 1822.  He was cremated on the beach under the supervision of his friend, the poet Lord Byron. There is a monument to Shelley in the town’s Piazza Paolina.

Italy’s first nuclear reactor opens

Facility based on pioneer Enrico Fermi’s historic Chicago-Pile series

The Ispra-1 reactor was the first nuclear
reactor to be built on Italian soil

The first nuclear reactor to be built on Italian soil was inaugurated on this day in 1959 at Ispra, a small town on the eastern shore of Lago Maggiore.

The facility, which preceded the first generation of nuclear power plants serving the need for clean, reliable and plentiful electricity sources for industrial and domestic use, was built purely for research purposes.

It was opened four years ahead of the country’s first commercial nuclear plant, at Latina in Lazio.

The 5 megawatt Ispra-1 research reactor, as it was titled, was modelled on the latest version of the Chicago-Pile 5 series developed by Enrico Fermi, the Rome-born nuclear physicist who created the world’s first nuclear reactor, the Chicago-Pile 1, following his discovery that if uranium neutrons were emitted into fissioning uranium, they could split other uranium atoms, setting off a chain reaction that would release enormous amounts of energy.

The Ispra-1 reactor was built by Italy’s National Nuclear Research Council. It was officially transferred to the European Community in March 1961, becoming a Joint Research Centre (JRC) of the European Commission. 

It was used for studies and research on core physics, new materials for the construction of nuclear power reactors, as well as neutron fluxes and their interaction with living matter.

Until the 1960s, much of Italy’s electricity had been generated from renewable sources. Although the first power plant in continental Europe, opened in Milan in 1883, was carbon-fuelled, the country’s abundance of mountains and lakes enabled it to develop a huge hydroelectric power sector.

The Trino Vercellese nuclear plant was named
after the Italian nuclear pioneer Enrico Fermi

Fossil fuels began to take over in the 1960s to meet the needs of a growing population but there was a common belief that nuclear energy could provide, within only a few years, safely and economically, all the power that Italy needed. 

By 1964, three nuclear power plants had been built, all approximately 50km (31 miles) from major cities. They were at Trino Vercellese, north of Turin, at Sessa Aurunca in Campania, north of Naples, and at Latina, south of Rome.

Yet after the electricity sector in Italy was nationalised in 1962, investment in nuclear stalled. It was not until 1978 that a fourth nuclear power station, at Caorso in Emilia-Romagna, was completed.  The 1973 world oil crisis had prompted another round of enthusiastic plans for the nuclear sector, but again they were ultimately downgraded.

The most significant setback of all followed the Chernobyl disaster of 1986, fallout from which affected parts of northern Italy and was blamed for a decline in birth rate in 1987. The Italian government organised a referendum to gauge public feeling about the future of nuclear power, the results of which led to a decision to close two plants and terminate work on another.

Another referendum in 2011 following a nuclear accident in Japan confirmed that public opinion had not shifted and a new company was created to take charge of decommissioning all nuclear sites in Italy, including the research facility at Ispra.

The Cattedrale di San Marco is an
example of Latina's architecture

Travel tip:

Latina, where one of Italy’s now-decommissioned nuclear power stations was opened in 1963, is a city built during the Fascist era of the 1920s and 1930s when Mussolini’s government fulfilled a pledge to drain the inhospitable, mosquito-ridden Pontine Marshes, visitors to which frequently became infected with malaria. Built on that reclaimed land, and originally called Littoria when it was established in 1932, its stands as a monument to the architectural style that typified the era, which combined some elements of classicism, with its preponderance of columns and arches, with the stark lines of 1920s and 30s rationalism. It has a large number of monuments and edifices, including a town hall with a tall clock tower and a cathedral, designed by architects such as Marcello Piacentini and Angiolo Mazzoni. Renamed Latina in 1946, it has grown into a substantial city with a population of 126,000, making it the second largest city in Lazio after Rome.

Ispra's coastal pathways are popular with
visitors to the Lago Maggiore town

Travel tip:

Ispra, which sits on the eastern shore of Lago Maggiore about 25km (16 miles) west of its provincial capital, Varese, is an area popular with walkers for its lakeside footpaths, including the poetically named passeggiata dell’amore, and with golfers for the Parco del Golfo della Quassa. The Joint Research Centre still exists, despite the decommissioning of the nuclear plant. It comprises the Institute for the Protection and the Security of the Citizen (IPSC), the Institute for Environment and Sustainability (IES) and the Institute for Health and Consumer Protection (IHCP). The site itself is an area of natural preservation, covering an area of 157 hectares (390 acres) of pine, birch, oak and chestnut trees.

Andrew Viterbi – electrical engineer and businessman

The amazing life of 'the father of the mobile telephone'

Even at the age of 88, Viterbi remains actively
involved in the scientific community

Andrew Viterbi, who invented the Viterbi algorithm and co-founded the American multinational corporation Qualcomm, was born Andrea Giacomo Viterbi on this day in 1935 in Bergamo in the Lombardy region of Italy.

The Viterbi algorithm is still used widely in cellular phones and other communication devices for error correcting codes as well as for speech recognition, DNA analysis and other applications. Viterbi also helped to develop the Code Division Multiple Access standard for cell phone networks.

He is recognised in Italy as ‘il padre del telefonino’ - the father of the mobile telephone.

Viterbi’s father, Achille, was director of Bergamo Hospital’s ophthalmology department, and his mother, Maria Luria, came from a prominent family in Piedmont and had a teaching degree. But after Mussolini introduced his new racial laws in Italy before the start of World War II, the couple, who were both Jewish, were deprived of their position and could no longer make a living to support their family.

They had planned to sail to the United States on 1 September, 1939, but after receiving a tip-off alerting them to possible danger, they secretly escaped two weeks early and were able to land safely in New York, where a member of their extended family already lived.   They then moved to Boston, where Andrea’s name was anglicised as Andrew after he was naturalised as an American.

Andrew Viterbi pictured in 2005 with his late wife,
Erna, who assisted him in his philanthropic causes

As Andrew Viterbi, he attended the Boston Latin School and entered Massachusetts Institute of Technology in 1952 to study electrical engineering. After qualifying, he worked at Raytheon and then the Jet Propulsion Laboratory at Pasadena, where he worked on telemetry for unmanned space missions and helped to develop the ‘phase-locked loop.’ At the same time, he was studying for a PhD in digital communications at the University of Southern California and graduated from there in 1963.

He was awarded academic positions at the University of California and, in 1967, he proposed the Viterbi algorithm to decode convolutionally encoded data, a ground breaking mathematical formula for eliminating signal interference. This allowed for effective cellular communication, digital satellite broadcast receivers, and deep space telemetry.

With Irwin Jacobs, Viterbi was the co-founder of Linkabit Corporation in 1968, and Qualcomm Inc in 1985, which became one of the most important communications companies worldwide. He became president of the venture capital company, The Viterbi Group in 2003, which invests in emerging businesses that are pioneering innovative technologies in the area of wireless communications.

Viterbi has received many awards for his invention of the Viterbi algorithm and a computer centre and an engineering school have been named after him. His algorithm paved the way for the widespread use of cellular technology, which changed the way people communicate worldwide.

In 2003 he was awarded an honorary degree in computer science by La Sapienza University of Rome and in 2007 an honorary degree in electrical engineering by the University in his native city of Bergamo. He has written two internationally respected books about digital communications and coding.

Viterbi in 1958 married Erna Finci, a Jewish refugee who had arrived in the United States from Sarajevo in the former Yugoslavia. Her family had been deported from an Italian occupied zone in Sarajevo to Parma in Italy, where they were interned. They were saved from being sent to an extermination camp by the residents of Gramignazzo di Sissa, the village when they were interned, and were looked after by a local family when the Germans advanced into Italy, who hid them in their vineyard. Other Italians helped them to walk across the Alps into Switzerland, where they stayed until after the war.

The couple had three children. Erna, who helped organise Viterbi’s multiple acts of philanthropy, died in 2015. Their charitable donations included $52 million to the University of Southern California, where the engineering school was renamed the Andrew and Erna Viterbi School of Engineering. 

Bergamo's Città Alta is protected by an
imposing wall built by the Venetians

Travel tip:

Bergamo in Lombardy is a beautiful city with an upper and lower town that are separated by impressive fortifications. The magical upper town - the Città Alta - has gems of mediaeval and Renaissance architecture surrounded by the impressive 16th century walls, which were built by the Venetians who ruled at the time. Outside the walls, the elegant Città Bassa, which grew up on the plain below, has some buildings that date back to the 15th century as well as imposing architecture added in the 19th and 20th centuries. While the Città Alta is the draw for many tourists, the lower town also has art galleries, churches and theatres and a wealth of good restaurants and smart shops to enjoy.

The Rocca dei Terzi with its
89ft central tower

Travel tip:

Gramignazzo, the village near Parma where Viterbi’s future wife, Erna, was saved with her family from being shipped to a Nazi extermination camp, is a frazione of the municipality of Sissa, in farming country on the south bank of the Po river in Emilia Romagna. Sissa has a restored castle, the Rocca dei Terzi, which dates back to the 11th century and is notable for a 27-metre (89ft) tower added in the 16th century. The village is host every November to a festival known as the Sapori del Maiale, celebrating products made from pork, including many varieties of sausage and salami as well as roast pork dishes such as porchetta, typically made of rolled loin or belly pork stuffed with herbs.
