Biography
Jean-Jacques Paulet (26 April 1740 – 4 August 1826) was a French physician, mycologist, and botanist from Anduze, France. He studied medicine at the University of Montpellier, one of Europe's oldest and most respected medical schools, and earned his doctorate in March 1764. His early career showed a wide-ranging interest in medicine and science that characterized his professional life for over sixty years.
After graduation, Paulet settled in Paris and published his first major work in 1765: *Histoire de la petite vérole, avec les moyens d'en préserver les enfants*, a study on smallpox and how to protect children from it. He also translated a smallpox treatise by Arab physician Abu Bakr Mohammad Ibn Zakariya al-Razi from the ninth or tenth century into French, making this classic medical text accessible to French readers. Between 1768 and 1776, he published three more books in Paris advocating for widespread measures to prevent smallpox, making him one of the early European voices calling for systematic public health actions against the disease.
Paulet's scientific interests went beyond smallpox. He wrote about ergotism for the *Mémoires de l'Académie de médecine*, working with well-known figures like Henri Alexandre Tessier (1741–1837) and Charles Jacques Saillant (1747–1814). He also strongly opposed animal magnetism, the controversial theory by Franz Anton Mesmer about a natural energy exchange between living things. In 1805, Paulet wrote a treatise on asp viper bites, and in 1815, he critically reviewed the history of medicine by German botanist and historian Kurt Sprengel.
His most lasting contributions were in mycology. His *Traité complet sur les champignons*, first published in 1775, was a key work on fungi study, providing systematic descriptions and classifications when mycology was still a new field. He revisited this subject in 1791 with another installment of the same title. In his later years, he also wrote two botanical works: *Examen de l'ouvrage de M. Stackhouse sur les genres de plantes de Théophraste* in 1816, and *La Botanique ou Flore et Faune de Virgile* in 1824, the latter analyzing the plants and animals in Virgil's works. On 22 October 1821, Paulet joined the French Academy of Sciences in the medicine and surgery section. He passed away on 4 August 1826 in Fontainebleau, France, at the age of eighty-six.
Before Fame
Paulet was born in 1740 in Anduze, a small town in the Gard department of southern France, when natural sciences were rapidly expanding across Europe. He studied medicine at the University of Montpellier, an institution with a long tradition in medicine and natural history, which had produced many of France's leading doctors and naturalists. Montpellier's curriculum combined practical medicine with an introduction to the natural world, likely fostering Paulet's interest in botany and fungi alongside his clinical studies.
After earning his doctorate in 1764, Paulet moved to Paris. There, access to the city's publishing houses, societies, and scientific networks allowed him to take on a wide range of scholarly projects. His early work on smallpox earned him recognition in medical circles, and his involvement with the Académie de médecine gave him a platform to join major scientific debates of the time. These productive and networking-rich early years set the stage for his later election to the Academy of Sciences and for his continued contributions as both a doctor and a naturalist.

Did You Know?
- 01.Paulet produced a French translation of a smallpox treatise written by the Arab physician Ibn Zakariya al-Razi, who lived in the ninth or tenth century, making this medieval medical text accessible to eighteenth-century French readers.
- 02.He was an outspoken critic of animal magnetism, the theory advanced by Franz Anton Mesmer that a universal magnetic fluid could be manipulated to heal disease, a controversy that captivated Parisian society in the 1780s.
- 03.Paulet's Traité complet sur les champignons of 1775 is considered a seminal work in mycology, published at a time when the systematic study of fungi was only beginning to take shape as a scientific discipline.
- 04.He published a treatise specifically on the bite of the asp viper in 1805, reflecting the period's broader interest in toxicology and venomous animals as subjects of medical inquiry.
- 05.His final major publication, La Botanique ou Flore et Faune de Virgile, appeared in 1824 when he was eighty-four years old, demonstrating scholarly productivity well into extreme old age.
