Francesco Redi - biologist and poet

Renaissance scholar who debunked scientific myths

Francesco Redi proved that maggots
resulted from flies' eggs

The physician Francesco Redi, famous for challenging a centuries old belief that certain living things arose through spontaneous generation rather than any reproductive process involving parent organisms, was born on this day in 1626 in Arezzo, Tuscany.

Redi, who enjoyed literary success alongside his work in experimental biology, devoted much of his scientific life to dismantling some of the widely held beliefs in his field that he was sure were incorrect.

The most famous of these was that the maggots frequently discovered in rotting meat occurred spontaneously as a product of the decaying flesh.

In order to show that this was a myth, Redi conducted a number of experiments in 1668 involving sets of jars containing dead fish and raw pieces of different meats. In the first, he sealed three of six jars and left the other three open. In the second, he placed raw meat in three jars, plugging one with a cork stopper, placing gauze over the other and leaving the third open.

After a period of time, the flesh in the open jars contained maggots, but in the sealed jars did not.  In the gauze-covered jar, maggots appeared on the surface of the gauze but not in the meat.

The cover of Redi's book about
the generation of insects

Redi’s belief was that maggots came from tiny eggs laid by flies on the surface of the rotting meat or fish. To add further weight to his theory, he captured some live maggots, which then metamorphosed into flies.

In a further experiment, he placed dead flies in one jar containing meat and live flies in another. Only in the jar with live flies did maggots appear in the meat.

These experiments were described in Redi’s magnum opus, Esperienze intorno alla generazione degl'insetti (Experiments on the Generation of Insects).

This is generally recognised as the first refutation of spontaneous generation, the belief in which went back at least 2,000 years to the time of the Greek philosopher Aristotle and possibly beyond. It was not entirely disproved until the mid-19th century. Redi’s work with maggots was also one of the first recorded examples of a scientific experiment using controls, which would later be recognised as an essential element of biological research. 

Earlier, Redi’s 1664 work Osservazioni intorno alle vipere (Observations on vipers) challenged some bizarre suppositions relating to vipers, which were thought for many years not only to be capable of shattering glasses but drinking wine.

Redi proved that the venom of the snake, which was thought to be harmful when swallowed, came not from the reptile’s gallbladder but was contained in fangs in the mouth and poisoned its victims by entering their bloodstream via a bite. He also showed that by tightening a ligature around a bitten limb, the venom could be prevented from reaching the victim’s heart.

As well as debunking myths, Redi also carried out considerable research in his major area of interest, parasitology.  His books on the subject described 180 species of parasites that he had identified.

Redi, whose father was an eminent physician, obtained degrees in medicine and philosophy at the University of Pisa. His career took him to Rome, Naples, Bologna, Padua and Venice before he settled in Florence, where he served at the Medici Court as both the head physician and superintendent of the ducal apothecary to Ferdinando II de' Medici, Grand Duke of Tuscany and his successor, Cosimo III. 

His major contribution to Italian literature was a collection of his poems published in 1685 called Bacco in Toscana (Bacchus in Tuscany), which he wrote in praise of Tuscan wine and is considered one of the finest works of 17th-century Italian poetry, and which prompted Cosimo III to award Redi a medal of honour.

Redi died in Pisa in 1697 at the age of 71. His remains were taken to Arezzo, where there is a funeral monument to him on the wall of the left nave of the city’s duomo, the Cattedrale di Ss. Donato e Pietro.

Science commemorated his life in several ways, including a crater on Mars named in his honour. The Redi Award has been given annually by the International Society on Toxinology since 1967, a scientific journal called Redia, an Italian journal of zoology first published in 1903, was named after him, as is a European viper subspecies, vipera aspis francisciredi.

Arezzo's sloping Piazza Grande is regarded as one
of the most beautiful squares in Tuscany

Travel tip:

Arezzo, the city of Redi’s birth, is one of the wealthiest cities in Tuscany. Situated at the confluence of four valleys - Tiberina, Casentino, Valdarno and Valdichiana – its medieval centre suffered massive damage during the Second World War but still has enough monuments, churches and museums to be a worthwhile stopover on tourist itineraries. Its main sights include the Basilica di San Francesco, with its beautiful frescoes by Piero della Francesca, the central Piazza Grande, with its sloping pavement in red brick, the Medici Fortress, the duomo and a Roman amphitheatre.

Arezzo's cathedral stands in an elevated location
a short distance from the city centre

Travel tip:

Arezzo’s original cathedral was built on the nearby Pionta Hill, over the burial place of Donatus of Arezzo, who was martyred in 363. In 1203 Pope Innocent III had the cathedral moved within the city's walls, to the current site in another elevated position a short walk from Piazza Grande.  The construction of the current structure started in 1278 and continued in phases until 1511, although the façade visible today, designed by Dante Viviani was not completed until 1914, replacing one left unfinished in the 15th century.  The interior contains several notable artworks, including a relief by Donatello, entitled Baptism of Christ, and a cenotaph to Guido Tarlati, lord of Arezzo until 1327, said to be designed by Giotto, near to which is Piero della Francesca's Mary Magdalene.  The wooden choir of the Grand Chapel was designed by Giorgio Vasari.

Giordano Bruno - 'martyr of science'

Dominican friar condemned as a heretic

Giordano Bruno, a Dominican friar, philosopher and cosmological theorist who challenged orthodox Christian beliefs in the 16th century, died on this day in 1600 when he was burned at the stake after being found guilty of heresy.  The principal crimes for which he was tried by the Roman Inquisition were the denial of several core Catholic doctrines.  Bruno challenged the divinity of Christ, the virginity of Mary, and the transubstantiation - the idea that Eucharistic offering of bread and wine in Mass becomes the body and blood of Christ.  He also questioned the idea of God as a holy trinity of divine persons - the Father, the Son (Jesus) and the Holy Spirit.  His own belief was closer to pantheism, which contends that a God is an all-encompassing divine presence rather than existing in some personal form with human traits.  This idea formed part of his cosmological theory, in which he supported the idea that everything in the universe is made of tiny particles (atoms) and that God exists in all of these particles.  Yet this was in contradiction of the established Catholic wisdom, as was his support for the idea advanced by the Renaissance astronomer Nicolaus Copernicus that Earth revolved around the sun, rather than the other way round.  Read more…

Arcangelo Corelli – musician

Baroque composer had a major influence on the development of music

Violinist and composer Arcangelo Corelli was born on this day in 1653 at Fusignano, a small town near Ravenna.   He is remembered for his influence on the development of violin style and for his use of the genres of sonata and concerto. Corelli’s 12 Concerti Grossi established the concerto grosso as a popular medium of composition.  Named Arcangelo after his father, who died a few weeks before his birth, he studied music with the curate of a neighbouring village before going to the nearby towns of Faenza and Lugo to learn musical theory.  Corelli later studied with Giovanni Benvenuti, who was a violinist at San Petronio in Bologna and in 1670 he started at the Philharmonic Academy in Bologna.  He moved on to Rome where to begin with he played the violin at a theatre. It is known that by 1677 he had written his first composition, a Sonata for Violin and Lute.  By 1675 Corelli was third violinist in the orchestra of the chapel of San Luigi dei Francesi and by the following year he had become second violinist. In 1681 his 12 Trio Sonatas for two violins and a cello were published and the following year he became first violinist in the San Luigi dei Francesi orchestra.  Read more…

Raffaele ‘Raf’ Vallone – actor

Movie star who had four careers

Raffaele Vallone, the stage and screen actor who was born on this day in 1916 in Tropea, Calabria, was remarkable for having embarked on three starkly different career paths even before he made his acting debut.  Usually known as Raf, he grew up from the age of two in Turin, where his father, an ambitious young lawyer, had relocated to set up a legal practice.  A natural athlete, he was a fine footballer – so good, in fact, that at the age of 14 he was snapped up by Torino FC, who made him an apprentice professional.  Compared with the average working man, he was handsomely paid as a footballer, and he won a medal as part of the Torino team crowned Coppa Italia winners in 1936.  Yet he quickly became bored with football and enrolled at Turin University, where he studied Law and Philosophy with a view to joining his father’s firm.  Ultimately, he baulked at the idea of becoming a lawyer, too, and instead joined the staff of the left-wing daily newspaper L’Unità, where he rose quickly to be head of the culture pages, at the same time establishing himself as a drama and film critic for the Turin daily La Stampa.  Read more…

Giovanni Pacini – opera composer

Works of overshadowed musician have enjoyed recent revival

Composer Giovanni Pacini, who wrote operas in the early part of the 19th century to suit the voices of the great singers of the period, was born on this day in 1796 in Catania in Sicily.  Pacini began his formal music studies at the age of 12, when he was sent by his father, the opera singer Luigi Pacini, to study voice in Bologna with castrato singer and composer, Luigi Marchesi.  He soon switched his focus to composing and wrote an opera, La sposa fedele - The Faithful Bride. It premiered in Venice in 1818 and, for its revival the following year, Pacini provided a new aria, to be sung specifically by the soprano Giuditta Pasta.  By the mid 1820s he had become a leading opera composer, having produced many successful serious and comic works.  Pacini’s 1824 work Alessandro nelle Indie - Alexander in the Indies - was a successful serious opera based on Andrea Leone Tottola’s updating of a text by librettist Pietro Metastasio.  But by the mid 1830s, Pacini had withdrawn from operatic activity after he found his operas eclipsed by those of Gaetano Donizetti and Vincenzo Bellini.  He settled in Tuscany, where his father had been born.  Read more…

Edda Dell’Orso – vocalist

Soprano was wordless voice of Morricone soundtracks

The singer Edda Dell’Orso, best known for the extraordinary range of wordless vocals that have featured in many of composer Ennio Morricone’s brilliant film soundtracks from the 1960s onwards, was born on this day in 1935 in Genoa.  Her collaboration with Morricone began when he was contracted in 1964 to provide the musical score for A Fistful of Dollars, the first of Sergio Leone’s so-called Spaghetti Western trilogy that was to make Clint Eastwood an international star.  Leone’s producers could only offer Morricone a small budget, which meant his access to a full orchestra was limited, forcing him to improvise and create sound effects in different ways. One idea he had was to replace instruments with human voices, which is where Dell’Orso, a distinctive soprano, came into her own.  Born Edda Sabatini, she had pursued her musical interests with the support of her father who, while not musical himself, could see that she had potential as a pianist.  The quality of her voice became clear when she enrolled at the National Academy of Santa Cecilia, the renowned music school in Rome, where she graduated in 1956 in singing and piano.  Read more…

Valentino Rossi - motorcycle world champion

Rider from Urbino among his sport's all-time greats

Valentino Rossi, the motorcycle racer whose seven 500cc or MotoGP world titles have established him as one of the sport's all-time greats, was born on this day in 1979 in Urbino.  Only his fellow Italian, Giacomo Agostini, the eight-times world champion, has more 500cc or MotoGP titles than Rossi, whose total of 88 race victories in the premier classification is the most by any rider.  Across all engine sizes, he has been a world champion nine times, behind only Agostini (15) and Spain's Ángel Nieto, who specialised in 50cc and 125cc classes.  Britain's Mike Hailwood and Italy's 1950s star Carlo Ubbiali also won nine world titles each.  Still competing at the highest level, Rossi has not won the world title since 2009 but continues to defy his age.  Rossi came from a motorcycling family, his father Graziano having competed on the grand prix circuit himself between 1977 and 1982. He won three races in the 250cc category in 1979, when he finished third in the overall classification.  When Valentino was still a child, the family moved to Tavullia, a small town between Urbino and Pesaro, on the Adriatic coast.  Read more…

Achille Castiglioni - designer

Leading figure in post-war Italian style

The designer Achille Castiglioni, whose innovative ideas for lighting, furniture and items for the home put him at the forefront of Italy’s post-war design boom, was born on this day in 1918 in Milan.  Many of his designs, including the Arco floor lamp for which he is most famous, are still in production today, even 17 years after his death.  The Arco lamp, which he designed in 1962 in conjunction with his brother, Pier Giacomo, combined a heavy base in Carrara marble, a curved telescopic stainless steel arm and a polished aluminium reflector.  Designed so that the reflector could be suspended above a table or a chair, the Arco was conceived as an overhead lighting solution for apartments that removed the need for holes in the ceiling and wiring, yet as an object of simple chic beauty it came to be seen as a symbol of sophistication and good taste.  The Arco was commissioned by the Italian lighting company Flos, which still produces numerous other lamps designed by Castiglioni.  Achille’s father was the sculptor Giannino Castiglioni. His brothers Livio and Pier Giacomo, both older, were architects.  Read more…

Angelo Peruzzi - footballer

Italy international who was twice world's costliest goalkeeper

The footballer Angelo Peruzzi, who made 31 appearances for Italy’s national team and was a member of Marcello Lippi’s victorious squad at the 2006 World Cup as well as winning the Champions League with Juventus, was born on this day in 1970 in Blera, a hilltop town in the province of Viterbo, north of Rome.  Peruzzi defied his relatively short and stocky physique to become one of the best goalkeepers of his generation, renowned not only for his physical strength but also for his positional sense, anticipation and explosive reactions.  These qualities enabled him to compensate for his lack of height and earned him a reputation for efficiency rather than spectacular stops yet he was much coveted by clubs in Italy’s Serie A.  Twice he moved clubs for what was at the time a world record transfer fee for a goalkeeper.  In 1999 he joined Internazionale of Milan (Inter Milan) from Juventus for €14.461 million but stayed at the Stadio Giuseppe Meazza for only a year before switching to Lazio in a deal worth €20.658 million.  That record stood for 11 years until Manchester United bought David de Gea from Atletico Madrid for €22 million in 2011.  Read more…

Giambattista Bodoni - type designer

Celebrity printer whose name lives on in type

Typographer, printer and publisher Giambattista Bodoni was born on this day in 1740 in Saluzzo in the region of Piedmont.  At the height of his career he became internationally famous and was complimented by the Pope and paid a pension by Napoleon.  Bodoni designed a modern typeface that was named after him and is still in use today.  His father and grandfather were both printers and as a child he played with their leftover equipment. He learnt the printing trade at his father’s side and at the age of 17 travelled to Rome to further his career.  Bodoni served an apprenticeship at the press of the Congregation for the Propagation of the Faith, the missionary arm of the Catholic Church.  In 1768 he was asked to assume management of the Duke of Parma’s Royal Press, where he produced Italian, Greek and Latin books.  He started using modern typefaces of his own design and came up with the typeface that retained the Bodoni name in 1790.  He became well known and important travellers visited his press to see him at work. Bodoni produced fine editions of the writings of Horace and Virgil in 1791 and 1793 respectively and Homer’s Iliad in 1808.  Read more…

Charlie Cairoli - circus clown

Milan-born performer who became a Blackpool legend

The circus clown Charlie Cairoli, who would at his peak set a world record by appearing at the Blackpool Tower Circus in England for 40 consecutive seasons, was born in Affori, now a suburb of Milan but then a town in its own right, on this day in 1910.  Cairoli performed at the Tower for the first time in 1939 and returned every year until 1979, quitting only when his health began to fail him.  The run was not broken even by the outbreak of the Second World War, which Britain entered soon after he arrived, or his own arrest as a suspected ‘enemy alien’. He was the Tower’s most popular attraction for almost all of those years.  Cairoli, though born in Italy, was actually from a French family, albeit one of Italian descent, who christened him Hubert Jean Charles Cairoli.  His father, Jean-Marie, was also a clown; his mother, Eugenie, came from another French circus family with Italian heritage, the Rocono. Charles - known as Carletto - and his brother Louis-Philippe became part of the show as young children. Carletto made his debut at the age of seven.   At that age, he was doing little more than fetching and carrying for his parents, who were the stars.  Read more…

Destruction of Monte Cassino Abbey

Historic monastery flattened in Allied bombing raid

The Abbey of Monte Cassino, established in 529 and the oldest Benedictine monastery in the world, was destroyed by Allied bombers on this day in 1944 in what is now acknowledged as one of the biggest strategic errors of the Second World War on the Allied side.  The Abbey was attacked despite an agreement signed by both sides with the Vatican that the historic building would be respected as occupying neutral territory.  But Allied commanders, who had seen their infantrymen suffer heavy casualties in trying to advance along the Liri valley, the route of the main highway between Naples and Rome, were convinced that the Germans were using the Abbey, which commands sweeping views of the valley, at least as a point from which to direct operations.  This perception was reinforced by a radio intercept, subsequently alleged to have been wrongly translated, which suggested a German battalion had been stationed in the Abbey, ignoring a 300-metre area around it that was supposed to be out of bounds to soldiers on both sides.   Knowing the outrage their action would prompt, military sources in Britain and the United States leaked details of their suspicions to the newspapers, who obligingly printed stories that seemed to justify the plan.   Read more…

Galileo Galilei – astronomer and physicist

Scholar has been judged to be the founder of modern science 

Renaissance scientist Galileo Galilei was born on this day in 1564 in Pisa.  His astronomical observations confirmed the phases of Venus, discovered the four largest satellites of Jupiter and analysed sunspots. Also among his inventions was a military compass.  Galileo was educated at a monastery near Florence and considered entering the priesthood but he enrolled instead at the University of Pisa to study medicine.  In 1581 he noticed a swinging chandelier being moved to swing in larger and smaller arcs by air currents. He experimented with two swinging pendulums and found they kept time together although he started one with a large sweep and the other with a smaller sweep. It was almost 100 years before a swinging pendulum was used to create an accurate timepiece.  He talked his father into letting him study mathematics and natural philosophy instead of medicine and by 1589 had been appointed to the chair of Mathematics at Pisa.  He moved to the University of Padua where he taught geometry, mechanics and astronomy until 1610.  Galileo met with opposition from other astronomers and was investigated by the Roman Inquisition in 1615.  Read more…

Totò – comic actor

50 years on, remembered still as Italy’s funniest performer

The comic actor Antonio De Curtis, universally known as Totò and still winning polls as the most popular Italian comedian of all time a half-century after his death, was born on this day in 1898 in Naples.  Totò had a distinguished career in theatre, wrote poetry and sang, but is best remembered for the 97 films in which he appeared between 1937 and his death in 1967, many of which were made simply as a platform for his inimitable talent.  Although he worked in dramatic roles for some of Italy’s most respected directors, it was for his comedy that he was most appreciated.  His characters were typically eccentric, his acting style sometimes almost extravagantly expressive both physically and vocally.  In his humour, he drew on his body and his face to maximum effect but also possessed an inherent sense of timing in the way he delivered his lines. Often, at the peak of his screen career with his characters so well defined, he would dispense with much of his script and simply ad lib, giving free rein to the cynicism and irreverence that came naturally.  Such was his popularity that after his death from a heart attack at the age of 69 he was given funerals both in Rome, where he lived, and in his native Naples.  Read more…
