Born in
Ardèche, France, he began his career at the Saint-Nicolas college and the Saint-Esprit seminary being ordained a priest in 1776. He initially served as vicar in Antraigues and moved around. Despite his ecclesiastical office, he spent much of his time studying the geology of his home in Southern France until he moved to Paris in 1778. He was elected as a member of the
American Philosophical Society in 1786. In 1780, with the backing of the
Académie des Sciences, he began publishing volumes of his
Histoire naturelle de la France Méridionale (1780–1784), which documented his geological and natural studies. Published in seven volumes, he was forced by the church to stop writing on geology after the fifth as it went against a literal reading of the bible. His suggestion on erosion and sediment accumulation implied that the earth was millions of years old. After arguments with Abbe Augustin de Barruel, the first volume was censored and republished. Soulavie's work influenced the thinking of
Benjamin Franklin. He frequented the salons of Paris and joined the
Académie des Inscriptions et Belles-lettres. Upon the onset of the
French Revolution, he backed the liberal reformists, represented the clergy at the Estates-General, and supported the Civil Constitution of the Clergy (1790). Two years later, he married and gained permission from the Pope to leave the priesthood. Having established himself in the literary world after compiling and publishing memoirs and correspondences of notable French historical figures, he earned the task of doing the same for the then recently dethroned
King Louis XVI. He died in Paris. ==References==
