Jean-Étienne Guettard (1715–1786) Jean-Etienne Guettard, curator of the Natural History collection of the Duke of Orléans, was the first to publicise the volcanic nature of the Chaîne des Puys. In 1752 he published a Memoir on the various mountains of France which he interpreted as having been volcanoes, based on the association of form and process. This was the first geomorphological approach to landscape. In addition he proposed that these mountains were potentially dormant rather than extinct, which  Basalt: provoked perhaps the greatest controversy in the history of geology. 8 Chaumont, 11 Fraisse, 14 Traversin;  : 1 Louchadière, 2 Jumes, 4 Coquille, 7 Gouttes, 9 Goules, Abraham Werner (1749-1817) & James (1726-1797) 15 Petit puy de Dôme, 16 Nid de Poule;  : In the second half of the 18th century the scientists allied themselves to one of two 5 Nugère, 12 Pariou; opposing groups, the Neptunists and the Plutonists.

He drew up the first geological map of the Chaîne des Puys and Monts Dore Massif, which terminology of Alfred Rittman (1962), as they are volcanic chain, whose human scale allows it to be was published in 1780. He belonged to the Plutonist camp, and he succeeded in demonstrating that the basaltic features observed were not marine in origin, but primary lava features.

He came up with a theory in 1802 to explain the origin of domes and other craterless volcanoes after visiting the Auvergne. He broadened this hypothesis by introducing the notion of the structures being ‘uplift craters’ (1819), and publication of this work proved contentious enough, once again, to divide the European geological community.

The Englishman, Scrope, after studying the volcanic rocks of Vesuvius, Etna and the Eiffel region, visited the the Auvergne several times in the 1820’s, culminating in the publication of his classic Memoir on the geology of Central France, including the Volcanic formations of Auvergne, the Velay and the Vivarais (1827), illustrated with his own maps and engravings. The revised edition was published under the title The Geology and extinct Volcanoes of Central France in 1858, and became very popular.

Maurice and Katia Krafft (1946-1991 and 1942-1991)

In the 1980’s it was the dream of the famous volcanologists, Maurice and Katia Krafft to create a European volcanology museum in the heart of the Chaîne des Puys. This became a reality in 2002 with the opening of Vulcania, a European centre for Volcanology, which Aerial view of the Chaîne des Puys seen from the north, with the Limagne Fault hidden by clouds houses a large part of their private collections.
