Joseph Jean Baptiste Xavier Fournet (May 15, 1801 – January 8, 1869), French geologist and metallurgist, was born at Strasbourg.
He was educated at the École des Mines in Paris, and after considerable experience as a mining engineer he was in 1834 appointed professor of geology at Lyon.
He was a man of wide knowledge and extensive research, and wrote memoirs on chemical and mineralogical subjects, on eruptive rocks, on the structure of the Jura, the metamorphism of the Western Alps, on the formation of oolitic limestones, on kaolinization and on metalliferous veins. On metallurgical subjects he also was an acknowledged authority; and he published observations on the order of sulphurability of metals (loi de Fournet).
He died in Lyon. His chief publications were: Études sur les dépôts métallifères (Paris, 1834); Histoire de la dolomie (Lyon, 1847); De l'extension des terrains houillers (1855); and Géologie lyonnaise (Lyon, 1861).

Alphonse Briart (1825–1898) was supervisor of the coal mines at Bascoup and Mariemont near Morlanwelz in the Hainaut province of Belgium, and a geologist who studied that region. During the period 1863–1896 he and Francois Cornet published a number of books and papers describing fossils and geological structures found near Mons. They devised theories - now generally accepted - as to the geological history of the region. After Cornet's death in 1887, Briart continued to write alone.
The mineral Briartite is named for his grandson, Gaston Briart. In 1890 his son Paul took part in Delcommune's Katanga expedition.

Charles Frederick Rogers (December 30, 1921 – disappeared June 23, 1965) was an American seismologist, pilot, and murder suspect who disappeared in June 1965 after police discovered the dismembered bodies of his elderly parents in the refrigerator of the Houston home all three shared, in what the media later dubbed "The Icebox Murders". Rogers has never been found and was declared dead in absentia in July 1975. He remains the only suspect in the murders, which are still considered unsolved.

Henry de Lumley (born 1934 in Marseille) is a French archeologist, geologist and prehistorian. He is director of the Institute of Human Paleontology in Paris, and Professor Emeritus at the Museum of Natural History in Paris. He is also a corresponding member of the Academy of Humanities of the Institute of France and former director of the French National Museum of Natural History. He is best known for his work on archeological sites in France and Spain, notably Arago cave in Tautavel, Southern France, Terra Amata in Nice and Grotte du Lazaret near Nice, and Baume Bonne at Quinson, where some of the earliest evidence of man in Europe were found.

Vincent E. Courtillot (born 6 March 1948) is an emeritus French geophysicist, prominent among the researchers who are critical of the hypothesis that impact events are a primary cause of mass extinction of life forms on the Earth. He is known for his book "La Vie en catastrophes" (Paris, Fayard, 1995), translated into English as "Evolutionary catastrophes" (1999).

François Bordes (December 30, 1919 – April 30, 1981), also known by the pen name of Francis Carsac, was a French scientist, geologist, archaeologist, and science fiction writer.
