Abbé Rozier

Jean-Baptiste François Rozier (born January 23, 1734 in Lyon , † on the night of August 28 to 29, 1793 there ) was a French botanist and agricultural scientist . Lay abbot in commendam , patron of Nanteuil-le-Haudouin , Seigneur de Chevreville. Its official botanical author's abbreviation is " Rozier ".


He studied in Villefranche-sur-Saône and temporarily at the seminary of St. Irenaeus of Lyon . He refuses to attend the seminary and devotes himself to science. Pauvre, his brother offers him the management of the family business near Vienne . He invites friends like Marc Antoine Louis Claret de La Tourrette (1729–1793) and Jean-Emmanuel Gilibert (1741–1814) to go on excursions to identify plants . He also met Claude Bourgelat (1712–1779), who opened a veterinary training center in Lyon. In 1761 Rozier became professor of botany and medical fields there. He founded a large botanical garden. In 1765 he becomes director of studies. But after differences of opinion with Bourgelat, Rozier lost his post there in 1769.

In 1775, the Académie des sciences in Paris commissioned Abbé Rozier to create a general register for the Académie. For the first time, Rozier introduces a standard format in the form of standardized playing cards as a card catalog .

He returned to the family domain, where he received Jean-Jacques Rousseau . Together with La Tourette, he published the book Démonstrations élémentaires de botanique in 1776 , which was reprinted several times.

Rozier settled in Paris in 1771, where he bought the Journal de Physique , which he published under the title Journal d'observations sur la Physique, l'Histoire naturelle et sur les Arts et Métiers . This appears over ten years. Anne Robert Jacques Turgot accompanied him to the south of France in 1775 to study local production. In 1777 he traveled to the Netherlands, accompanied by Nicolas Desmarest , to study mills.

In 1779 he moved to the vicinity of Béziers (domaine de Beauséjour), where he began his universal or dictionary of agriculture. With this work Rozier has significantly promoted agriculture. It was a pioneer in many areas. His philosophical convictions exposed him to the persecution of the envious and ignorant. The Bishop of Béziers, Aymar Claude de Nicolaï, even went so far as to build a road through his property at the expense of the province. In 1786 Rozier took over the management of the agricultural school in Lyon. He returned to Lyon a few years later and enthusiastically supported the beginning of the revolution. At the first two assemblies it proposes the creation of a national agricultural school.

Rozier was killed in an explosion in his home during the siege of Lyon in 1793.

Economic activity

Rozier was instrumental in editing the Journal de physique founded by Jacques Gautier d'Agoty (1716–1785) , which he continued under the title Observations sur la physique, sur l'histoire naturelle et sur les arts .
