Giovanni Caselli - inventor

Priest and physicist who created world’s first ‘fax' machine

Although Caselli was ordained as a priest in
1836 he devoted his life to the study of science

Giovanni Caselli, a physics professor who invented the pantelegraph, the forerunner of the modern fax machine, was born on this day in 1815 in Siena.

Caselli developed a prototype pantelegraph, which was capable of transmitting handwriting and images over long distances via wire telegraph lines, in 1856, some 20 years ahead of the patenting of Alexander Graham Bell’s telephone in the United States. It entered commercial service in France in 1865.

The technology was patented in Europe and the United States in the 1860s, when it was also trialled in Great Britain and Russia, but ultimately in proved too unreliable to achieve universal acceptance and virtually disappeared from popular use until midway through the 20th century.

Caselli spent his early years in Florence studying physics, science, history and religion and was ordained as a priest in the Catholic Church when he was 21.

In 1841 he was appointed tutor to the sons of Count Marquis Sanvitale of Modena in Parma, where he spent eight years before his time there was abruptly ended by expulsion from the city as a result of his participation in an uprising against the ruling House of Austria-Este.

A model of Caselli's device can be seen
at the Leonardo da Vinci museum in Milan 

He returned to Florence in 1849, when he became a professor of physics at the University of Florence.  It was at this time that he began to study electrochemistry, electromagnetism, electricity and magnetism. He also launched a journal with the intention of explaining the science of physics in layman's terms.

Alexander Bain and Frederick Bakewell were two other physicists working on similar technology at the same time as Caselli but were unable to achieve the necessary synchronization between the transmitting and receiving parts so they would work together correctly. Caselli, though, built in a regulating clock that made the sending and receiving mechanisms work together.

In Caselli’s device, an image was made using non-conductive ink on tin foil, over which a stylus passed, lightly touching the foil, which conducted electricity where there was no ink and not where there was ink, causing circuit breaks that matched the image.

The signals were then sent along a long distance telegraph line to a receiver, where an electrical stylus reproduced the image line-by-line using blue dye ink on white paper.

In 1856, Caselli presented his prototype to Leopold II, Grand Duke of Tuscany, who was impressed enough to give Caselli some financial support, before he moved to Paris to introduce his invention to Napoleon III.

Lyon using Caselli's pantelegraph in 1862

Napoleon embraced the technology with great enthusiasm, and between 1857 and 1861 Caselli worked on perfecting his pantelegraph, sometimes known as the Autotelegraph or Universal Telegraph, with the French mechanical engineer Léon Foucault.

After seeing a demonstration of Caselli's improved pantelegraph in 1860, Napoleon gave Caselli the chance to test in within the French national telegraph network, providing him with financial backing. Among the successful tests was one between Paris and Amiens, over a distance of 140km (87 miles) of a document bearing the signature of the composer Gioachino Rossini. 

After a further successful test between Paris and Marseille, commercial operations started in 1865, first between Paris and Lyon line, extending to Marseille in 1867.

After patenting his device in Europe in 1861 the United States in 1863, and receiving the Legion d’Honneur from Napoleon in recognition for his work, Caselli oversaw trials in England and Russia, where Tsar Alexander II used the system to send documents between his palaces in Saint Petersburg and Moscow between 1861 and 1865.

In the first year of operation, Caselli’s pantelegraph transmitted almost 5,000 'faxes'.

Yet Caselli could not develop the technology quickly enough for reliability issues to be solved and eventually interest in it began to decline to the extent that he effectively abandoned it and returned to Florence, where he died in 1891 at the age of 76.

Although in the 1920s, the AT & T Corporation developed a way to transmit images using radio signals, it was not until 1964 that the Xerox Corporation introduced the first commercial fax machine of the kind recognisable today.

Many of Caselli’s patents, letters and proofs of teleautographic transmission are kept at the municipal library of Siena. Others can be found in the archives of the Museo Galileo in Florence.

The shell-shaped Piazza del Campo in Siena is regarded
as one of the finest medieval squares in Europe

Travel tip: 

Siena, where Caselli was born, is famous for its shell-shaped Piazza del Campo, established in the 13th century as an open marketplace on a sloping site between the three communities that eventually merged to form Siena. It is regarded as one of Europe's finest medieval squares. The red brick paving, put down in 1349, fans out from the centre in nine sections. It has become well known as the scene of the historic horse race, the Palio di Siena.  Siena also has a beautiful Duomo - the Cathedral of St Mary of the Assumption - which was designed and completed between 1215 and 1263, its façade built in Tuscan Romanesque style using polychrome marble.

Piazza San Marco in Florence, a short distance from the centre
of the city, is the home of the University of Florence

Travel tip:

The University of Florence, the headquarters of which is in Piazza San Marco in the centre of the city, can trace its roots to the Studium Generale, which was established by the Florentine Republic in 1321. The Studium was recognized by Pope Clement VI in 1349, and included Italy’s first faculty of theology. The Studium became an imperial university in 1364, but was moved to Pisa in 1473 when Lorenzo the Magnificent gained control of Florence. Charles VIII moved it back from 1497–1515, but it was moved to Pisa again when the Medici family returned to power.  The modern university dates from 1859, when a group of institutions formed the Istituto di Studi Pratici e di Perfezionamento, which a year later was recognized as a full-fledged university, and renamed as the University of Florence in 1923.

Alessandro Costacurta - footballer 

AC Milan defender played in Serie A until 41 years old

Former AC Milan and Italy defender Alessandro Costacurta was born on this day in 1966 in the town of Orago, near Varese. Costacurta retired in May 2007, 25 days after his 41st birthday, having played more than 660 matches for Milan over the course of 21 seasons.  He is the oldest outfield player to appear in a Serie A match. Milan lost his final game 3-2 at home to Udinese but Costacurta marked the occasion with a goal, from the penalty spot.  It was only his third goal in 458 Serie A appearances for the rossoneri, but made him Serie A's oldest goalscorer.  He enjoyed a career laden with honours, including seven Serie A titles and five European Cups or Champions League titles. He also won 59 caps for Italy and was a member of the team that finished runners-up in the 1994 World Cup in the United States. Read more…

Luigi Lavazza - coffee maker

From a grocery store in Turin to Italy's market leader

Luigi Lavazza, the Turin grocer who founded the Lavazza Coffee Company, was born on this day in 1859 in the small town of Murisengo in Piedmont.  He had lived as a peasant farmer in Murisengo but times were hard and after a couple of poor harvests he decided to abandon the countryside and head for the city, moving to Turin and finding work as a shop assistant.  The Lavazza brand began when Luigi had saved enough money to by his own shop in Via San Tommaso, in the centre of Turin, in 1895.  He sold groceries and provisions and where other stores simply sold coffee beans, he had a workshop in the rear of the store where he experimented by grinding the beans and mixing them into different blends. When the first automatic roasting machines went into production in the 1920s, he was one of the first in Italy to buy one. Read more…

Giuseppe Panza - art collector

Businessman amassed more than 2,500 pieces

The art collector Giuseppe Panza di Biumo, whose fascination with postwar art, particularly American, led him to build up one of the world’s most important collections, died on this day in 2010 in Milan.  A businessman who succeeded his father in making money from wine and property, Panza acquired more than 2,500 pieces in his lifetime, many of which he sold or donated to museums and art galleries.  Some he parted with for millions of dollars, although he always insisted that his motivation was never financial gain but the love of art.  Approximately 10 per cent of his collection remains in the 18th-century Villa Menafoglio Litta, his family home at Varese, north of Milan, where he created 50,000 square feet (4,600 sq m) of exhibition space.  Read more…

Stefano Bontade - Mafia supremo

Well-connected Cosa Nostra boss had links to ex-premier Andreotti

Stefano Bontade, one of the most powerful and well connected figures in the Sicilian Mafia in the 1960s and 1970s, was born on this day in 1939 in Palermo, where he was murdered exactly 42 years later in a birthday execution that sparked a two-year war between the island’s rival clans.  Known as Il Falco – the Falcon – he was said to have close links with a number of important politicians on Sicily and with the former Italian prime minister Giulio Andreotti.  He was strongly suspected of being a key figure in the 1962 murder of Enrico Mattei, the president of Italy’s state-owned oil and gas conglomerate ENI, and in the bogus kidnapping of Michele Sindona, the disgraced banker who used the Vatican Bank to launder the proceeds of Cosa Nostra heroin trafficking.

Gaspara Stampa – poet

Gaspara Stampa is seen by some
as Italy's greatest female poet

Beautiful sonnets were inspired by unrequited love

Gaspara Stampa, the greatest female poet of the Italian Renaissance, died on this day in 1554 in Venice at the age of 31.

She is regarded by many as the greatest Italian female poet of any age, despite having had such a brief life.

Gaspara was born in Padua and lived in the city until she was eight years old. Her father, Bartolomeo, had been a jewel and gold merchant, but after he died, Gaspara’s mother, Cecilia, took her three children to live in Venice. They were accommodated in the house of Geronimo Morosini, who was descended from a noble Venetian family, in the parish of Santi Gervasio and Protasio, now known as San Trovaso. 

Along with her sister, Cassandra, and brother, Baldassare, Gaspara was educated in literature, music, history and painting. She excelled at singing and playing the lute and her home became a cultural hub as it was visited by many Venetian writers, painters and musicians, among them Francesco Sansovino, a poet and writer who was the son of the great Florentine architect, Jacopo Sansovino.

Gaspara dedicated most of her poems to Count Collatino di Collalto of Treviso, with whom she had an affair.

Much of Gaspara Stampa's best work came after she
had suffered a break-up with her lover 

When he broke off the relationship she was devastated and suffered from depression, but she wrote some of her most beautiful poems at this time, creating for herself a lasting literary reputation.

Only three of her poems were published during her lifetime although many were circulated among her literary friends in Venice.

Gaspara went to live in Florence for some time because of poor health, hoping that the milder climate might help her. But on her return to Venice in 1554 she became ill with a fever and died after 15 days on April 23. The parish register recorded the cause of her death as ‘fever, colic and mal di mare', which today would be understood as 'seasickness', although the theory has also been put forward that it could have been a suicide.

The first edition of Gaspara Stampa’s poetry, Rime di Madonna Gaspara Stampa, was published in Venice six months after her death.

Gaspara’s 311 poems are considered to be the most important collection of female poetry of the 16th century. They were edited by Gaspara’s sister, Cassandra, and the edition was dedicated to the Florentine poet and writer, Giovanni della Casa.

The 19th century German poet, Rainer Maria Rilke, refers to Gaspara Stampa in the first of his Duino Elegies, which were written while he was staying at Duino Castle on the Adriatic coast near Trieste. The Duino Elegies are now considered his greatest work.

Giotto's extraordinary decoration of the Scrovegni Chapel.
which is one of the highlights of a visit to Padua

Travel tip:

The city of Padua in the Veneto, where Gaspara Stampa was born, is one of the most important centres for art in Italy. Padua has become acknowledged as the birthplace of modern art because of the Scrovegni Chapel, the inside of which is covered with frescoes by Giotto, an artistic genius who was the first to paint people with realistic facial expressions showing emotion. His scenes depicting the lives of Mary and Joseph, painted between 1303 and 1305, are considered his greatest achievement and one of the world’s most important works of art.

The two facades of the Chiesa di San Trovaso, the
centrepiece of the neighbourhood of the same name

Travel tip:

San Trovaso is a neighbourhood within the Dorsoduro sestiere of Venice, just across the Accademia Bridge from the bustle of San Marco. At its heart is the Chiesa di San Trovaso, a church dedicated to the saints Gervasio and Protasio, rebuilt in 1584 on the site of a former church built in the 11th century. The church contains works of art by Domenico Tintoretto as well as his father, Jacopo, and by Michele Giambono and Palma il Giovane. The church is unusual in that it has two facades, one looking out across the Rio de San Trovaso canal, the other facing the Rio del Ognisanti. San Trovaso is also home to Venice’s oldest working gondola yard, the 17th-century Squero di San Trovaso, one of only two surviving squeri in Venice.
