Ferdinand Andr Fouqu

French geologist and petrologist who rendered much assistance on the Geological Survey of France, but in the course of time gave his special attention to the study of volcanic phenomena and earthquakes, to minerals and rocks; and he was the first to introduce modern petrographical methods into France. He also worked on volcanic gas analyses, using the methods of Robert Bunsen, notably on the island of Santorini, Greece. One prominent student of his was Alfred Lacroix, to whom Fouqué's daughter was married. His studies of the eruptive rocks of Corsica, Santorini and elsewhere; his researches on the artificial reproduction of eruptive rocks, and his treatise on the optical characters of feldspars deserve special mention; but he was perhaps best known for the joint work which he carried on with his friend Auguste Michel-Lévy. His chief publications were Santorin et ses éruptions (1879), Minéralogie micrographique : roches éruptives françaises (1879) and Synthèse des minéraux et des roches (1882); the latter two works written in collaboration with Auguste Michel-Lévy. He died on 7 March 1904, aged 75, in Paris. Link to Wikipedia biography
