Maria Gaetana Agnesi, the first woman to write a mathematics handbook, was born on this day in 1718 in Milan.

Maria became a mathematician, philosopher, theologian and humanitarian and was also the first woman to be appointed as a mathematics professor at a university.

She was one of at least 21 children born to Pietro Agnesi, a wealthy man whose family had made their money from silk production. Her mother was his first wife, Anna Fortunato Brivio, who was from a noble Milanese family.

Maria was soon recognised as a child prodigy, who could speak Italian and French by the time she was five and had learnt Greek, Hebrew, Spanish, German and Latin by the time she was 11.

When she became ill at the age of 12, it was thought to have been because of excessive studying and reading, but after she was prescribed vigorous dancing and horse riding to improve her health, she suffered convulsions and was then advised to moderate her activities.

By the time Maria was 14 she was studying ballistics and geometry. Her father regularly invited learned men to his house to listen to her read and to discuss philosophical questions with her.

After Maria’s mother died, her father remarried twice and Maria was given the task of teaching all her siblings and half-siblings.

This stopped her from fulfilling her wish to enter a convent.  Instead, her father agreed to let her live away from society and devote herself to the study of mathematics.

In 1740 she began studying differential and integral calculus with esteemed Italian mathematician Ramiro Rampinelli.

By 1748 Maria had published her Instituzioni analitiche ad uso della gioventù italiana. She said this was to give a systematic illustration of the different results and theorems of infinitesimal calculus. The work was translated into French and English and Maria received letters and gifts from the Habsburg Empress Maria Theresa and Pope Benedict XIV.

In the book, Maria discusses a curve that had been studied earlier by the mathematician Luigi Guido Grandi. He had called the curve ‘versoria,’ the Latin word for a rope that turns a sail, because that is what it reminded him of.  This was mistranslated as the word ‘witch’ in the English version and so the curve became known as ‘The Witch of Agnesi’.

In 1750 Pope Benedict XIV appointed Maria to the chair of mathematics and natural philosophy and physics at Bologna University, although she never actually taught there. She was the second woman in the world to be granted a professorship at a university, Laura Bassi, an Italian physicist being the first.

After the death of her father in 1752, Maria finally had the chance to study theology. She then worked with the poor, sick and homeless, founding a home for the elderly in Milan, where she went to live.

In January 1799, Maria Gaetana Agnesi died at the age of 80. She was buried in a mass grave for the poor along with 15 other bodies.

An asteroid, 16765 Agnesi, a crater on Venus and a brandy are all named after her, as well as the mathematical curve, the Witch of Agnesi.

Travel tip:

You can visit the Villa Agnesi Albertoni, where Maria and her family spent time during the summer, which is in Largo Maria Gaetana Agnesi at Montevecchia in the province of Lecco, about 30 kilometres (19 miles) northeast of Milan. The villa has been preserved in the rococo style in which it was built during the 17th century. Visitors can still see the ‘salotto’, where eminent visitors would discuss philosophy with Maria Gaetana Agnesi and hear one of her sisters, Maria Teresa Agnesi play her own compositions on the harpsichord.

Travel tip:

Bologna University, where Maria Gaetana Agnesi was the first woman to be appointed as a mathematics professor, was founded in 1088, making it the oldest university in the world. It attracted popes and kings as well as students of the calibre of Dante, Copernicus and Boccaccio. You can still visit one of the original university buildings in the centre of Bologna, the former anatomy theatre, the Archiginnasio, in Piazza Galvani. It is open Monday to Saturday from 9 am to 1 pm, admission free.

Lazzaro Spallanzani – priest and scientist

18th century biologist who pioneered artificial insemination

Lazzaro Spallanzani, the first scientist to interpret the process of digestion and the first to carry out a successful artificial insemination, died on this day in 1799 in Pavia.

Spallanzani made important contributions to the experimental study of bodily functions and animal reproduction. His investigations into the development of microscopic life in nutrient culture solutions paved the way for the later research of Louis Pasteur.

Born in Scandiano in the province of Reggio Emilia, the son of a wealthy lawyer, Spallanzani attended a Jesuit college and was ordained as a priest but then went to Bologna to study law.

Influenced by the eminent Laura Bassi, a professor of physics at the University, Spallanzani became interested in science.

Laura Bassi, whose work at the University
of Bologna influenced Spallanzani
In 1754 Spallanzani was appointed professor of logic, metaphysics and Greek at a college in Reggio and he later became a professor of physics at the University of Modena.

Spallanzani experimented in transplantation, successfully transplanting the head of one snail on to the body of another.

After a series of experiments on digestion, he obtained evidence that digestive juices contain special chemicals that are suited to particular foods.

He also performed in vitro fertilisation on frogs and, in 1780, artificial insemination on a dog, the first successful experiment of its kind on any animal recorded anywhere in the world.

As Spallanzani’s fame grew he received many offers from scientific societies throughout Europe but he accepted a chair at the University of Pavia in 1769, where he remained for the rest of his life.

He took every opportunity to travel in order to study new phenomena and to meet other scientists.

In 1788 he visited Vesuvius in Campania and the volcanoes of the Lipari islands and Sicily and recorded the results of his research in a large work, Viaggi alle due Sicilie ed in alcune parti dell’Appennino.

Spallanzani died from bladder cancer on 12 February 1799 in Pavia. After his death his bladder was removed for study by his colleagues and it was then placed on public display in a museum in Pavia, where it remains to this day.

A number of medals and coins have been struck to commemorate Spallanzani's achievements, including one produced for the 14th International Congress of Physiology, in Rome, in 1932, designed by Renato Brozzi.

There is a statue of Lazzaro Spallanzani showing him examining a frog through a magnifying glass, in his home town of Scandiano, which is near Reggio Emilia in Emilia-Romagna. The town was founded in 1262 when a defensive castle was built and some houses later developed around it. The town is now an important centre for the production of tiles.

Travel tip:

Pavia, where Lazzaro Spallanzani died, is a city in Lombardy, south of Milan. It is famous for its university, where Spallanzani taught, which was founded in 1361, and for its Certosa, a magnificent monastery complex north of the city that dates back to 1396. A pretty covered bridge over the River Ticino in the centre of Pavia leads to Borgo Ticino, an area where the inhabitants claim to be the true people of Pavia and are of Sabaudian origin, which means they are connected with the House of Savoy, from where the rulers of Italy came.

Laura Bassi – scientist

Ground-breaking academic paved the way for women


This portrait of the physicist Laura Bassi is said to date back to 1732

Brilliant physicist Laura Bassi died on this day in 1778 in Bologna.

She had enjoyed a remarkable career, becoming the first woman to earn a Chair in Science at a university anywhere in the world.

When she was just 13 her family’s physician had recognised her potential and took charge of her education.

When she was 20 he invited philosophers from the University of Bologna along with the Archbishop of Bologna, who later became Pope Benedict XIV, to examine her progress.

They were all impressed and Bassi was admitted to the Bologna Academy of Sciences as an honorary member, the first female ever to be allowed to join.

Her theses at the university showed influences of Isaac Newton’s work on optics and light. She was a key figure in introducing his ideas about physics to Italy.

When she received her degree from the university there was a public celebration in Bologna.

Another of her theses about the property of water led to her being awarded the post of Professor of Physics at the university.

As a woman, she was not allowed to teach at the university so she gave lessons and did experiments in her own home.

She was appointed to the Chair of experimental physics at Bologna University in 1776.

She died two years later, having made physics a lifelong career and broken new ground for women in academic circles.

A street in Bologna and a crater on Venus are named after her.

Laura Bassi was married at the Basilica of San Petronio in 1738

Travel Tip:

The Basilica di San Petronio, where Laura Bassi was married, is the main church of Bologna, located in Piazza Maggiore in the centre of the city. It is the largest brick-built Gothic church in the world. Building work began on the church in 1390 and it was dedicated to San Petronio, who had been the Bishop of Bologna in the fifth century. The facade was designed by Domenico da Varignana and started in 1538 by Giacomo Ranuzzi but was never finished. Despite being Bologna’s most important church, San Petronio is not the city’s cathedral. This is the Duomo di San Pietro, which stands nearby on Via Indipendenza. In the 16th century, the basilica staged the coronation of Charles V to Holy Roman Emperor by Pope Clement VII.
