Maria Gaetana Agnesi (

philosopher, theologian, and humanitarian. She was the first woman to write a mathematics handbook and the first woman appointed as a mathematics professor at a university.[5]

She is credited with writing the first book discussing both

integral calculus and was a member of the faculty at the University of Bologna
, although she never served.

She devoted the last four decades of her life to studying

charitable work and serving the poor. She was a devout Catholic and wrote extensively on the marriage between intellectual pursuit and mystical contemplation, most notably in her essay Il cielo mistico (The Mystic Heaven). She saw the rational contemplation of God as a complement to prayer and contemplation of the life, death and resurrection of Jesus Christ.[6]

Maria Teresa Agnesi Pinottini, harpsichordist and composer, was her sister.

Early life

Maria Gaetana Agnesi was born in

Anna Fortunato Brivio of the Brivius de Brokles family in 1717. Her mother's death provided her the excuse to retire from public life. She took over the management of the household. She was one of 21 children.[11] Her family was recognized as one of the wealthiest in Milan.[citation needed
]

Agnesi's diploma from Università di Bologna

Maria was recognized early on as a

Hebrew, Spanish, German, and Latin, and was referred to as the "Seven-Tongued Orator".[12]

Agnesi suffered a mysterious illness at the age of twelve that was attributed to her excessive studying and reading, so she was prescribed vigorous dancing and horseback riding. This treatment did not work; she began to experience extreme convulsions, after which she was encouraged to pursue moderation. By age fourteen, she was studying ballistics and geometry.[12] When she was fifteen, her father began to regularly gather in his house a circle of the most learned men in Bologna, before whom she read and maintained a series of theses on the most abstruse philosophical questions. Records of these meetings are given in Charles de Brosses' Lettres sur l'Italie and in the Propositiones Philosophicae, which her father had published in 1738 as an account of her final performance, where she defended 190 philosophical theses.[12]

Her father remarried twice after Maria's mother died, and Maria Agnesi ended up the eldest of 21 children, including her half-siblings. Her father agreed with her that if she were to continue her mathematics research, then she would be permitted to do all the charity work she wanted.

Olivetan monk who was one of the most notable Italian mathematicians of that time.[15] During that time, Maria studied with him both differential and integral
calculus.

Contributions to mathematics

Instituzioni analitiche

First page of Instituzioni analitiche (1748)

According to Britannica, she is "considered to be the first woman in the Western world to have achieved a reputation in mathematics". The most valuable result of her labours was the Instituzioni analitiche ad uso della gioventù italiana, (Analytical Institutions for the Use of Italian Youth) which was published in Milan in 1748 and "was regarded as the best introduction extant to the works of

Charles René Reyneau.[15] In this treatise, she worked on integrating mathematical analysis with algebra.[12] The first volume treats the analysis of finite quantities and the second of the analysis of infinitesimals
.

A French translation of the second volume by P. T. d'Antelmy, with additions by Charles Bossut (1730–1814), was published in Paris in 1775; and Analytical Institutions, an English translation of the whole work by John Colson (1680–1760), the Lucasian Professor of Mathematics at Cambridge, "inspected" by John Hellins, was published in 1801 at the expense of Baron Maseres.[16] The work was dedicated to Empress Maria Theresa, who thanked Agnesi with the gift of a diamond ring, a personal letter, and a diamond and crystal case. Many others praised her work, including Pope Benedict XIV, who wrote her a complimentary letter and sent her a gold wreath and a gold medal.[12]

In writing this work, Agnesi was advised and helped by two distinguished mathematicians: her former teacher Ramiro Rampinelli and Jacopo Riccati.[15]

Witch of Agnesi

In Instituzioni analitiche, Agnesi discussed a curve earlier studied and constructed by

Guido Grandi
.

Agnesi described the curve as versiera in Italian, which is a synonym for the adjective versoria meaning "turning in every direction".[17] At the same time versiera was used as a term for a "she-devil" or "witch", from Latin Adversarius, an alias for "devil" (Adversary of God). Future translations and publications of the Instituzioni analitiche carried forward the former meaning either as a translation error or possibly as a pun.[18] The curve has become known as the "Witch of Agnesi".[19]

Other

Agnesi also wrote a commentary on the Traité analytique des sections coniques du marquis de l'Hôpital which, though highly praised by those who saw it in manuscript, was never published.[20]

Later life

In 1750, on the illness of her father, she was appointed by

Fathers and devoted herself to the poor, homeless, and sick, giving away the gifts she had received and begging for money to continue her work with the poor. In 1783, she founded and became the director of the Opera Pia Trivulzio, a home for Milan's elderly, where she lived as the nuns of the institution did.[12] On 9 January 1799, Maria Agnesi died poor and was buried in a mass grave for the poor with fifteen other bodies.[22]

Recognition

In 1996, an asteroid, 16765 Agnesi, was named after Agnesi.

There is a crater on Venus named Agnesi after her.[23]

She is included in a deck of playing cards featuring notable women mathematicians published by the

Association of Women in Mathematics.[24]
