Who was Barthélemy Faujas de Saint-Fond?

Barthélemy Faujas de Saint-Fond, French geologist and traveller, was born at Montélimar. He was educated at the Jesuit's College at Lyon; afterwards he went to Grenoble where he studied law and was admitted as an advocate to the parlement.

He rose to be president of the seneschal's court in Montélimar, where he acquitted himself with distinction. However, he became disenchanted with law and wished to pursue his love of nature that had begun earlier in his life. His favorite pastime was visiting the mountain regions in the Alps and Massif Central. There be began to study the forms, structure, composition and superposition of rocks.

In 1775 in the Velay he discovered a rich deposit of pozzuolana, that was eventually mined by the government. In 1776 he established a relationship with Buffon, who recognised the value of his scientific efforts immediately. Invited by Buffon to Paris, Faujas ceased his legal work and was appointed assistant naturalist to the natural history museum by Louis XVI. Later, he was appointed royal commissioner for mines.

One of his most important works was Recherches sur les volcans éteints du Vivarais et du Velay, which appeared in 1778. This publication documented his astute observations allowing Faujas to develop a theory about the origin of volcanoes. In his capacity of commissioner for mines Faujas travelled to most European countries where he closely observed the natural environment and the rock formations. Faujas was the first to recognize the volcanic nature of the basaltic columns of Fingal's Cave, on Staffa. The island was visited in 1772 by Sir Joseph Banks, who remarked that the stone was a coarse kind of basalt, very much resembling the Giant's Causeway in Ireland as noted in. Faujas' Voyage en Angleterre, en Écosse et aux Îles Hébrides contains anecdotes about Sir Joseph Banks and Dr. John Whitehurst, including an amusing account of The Dinner of an Academic Club, which was translated into English.
