Joseph Henri Ferdinand Douvillé (16 June 1846 – 19 January 1937), also known as Henri Douvillé, was French paleontologist, geologist and malacologist. Douvillé worked as a mining engineer in Bourges (1872) and Limoges (1874), afterwards serving as professeur suppléant of paleontology at the École des Mines.

In 1888, he became lecturer at Aix-Marseille University, and in 1889 he became professor of geology at the University of Lyon.

He was an advocate of the controversial prehistoric artifacts findings of Glozel. Along with Edward Drinker Cope, his name is associated with the so-called "Cope-Depéret rule", a law which asserts that in population lineages, body size tends to increase over evolutionary time.

Augustin Alexis Damour (19 July 1808, in Paris – 22 September 1902, in Paris) was a French mineralogist who was also interested in prehistory.

Georges Augustin Albert Charpy (1 September 1865 – 25 November 1945) was the French scientist who created the Charpy impact test. He attended École Polytechnique from 1885 to 1887 and graduated with a degree in Marine Artillery. In 1887 he became a professor at École Monge. In 1892 he published his physics thesis. In 1920 he became a professor of metallurgy at École Nationale Supérieure des Mines de Paris. In 1922 he became the professor of general chemistry at École Polytechnique.

Charles Eugène Bertrand (2 January 1851, in Paris – 18 August 1917) was a French botanist, paleobotanist and geologist. He is remembered for his research involving the formation of coal.
He studied sciences in Paris, where he had as influences botanist Joseph Decaisne and plant physiologist Pierre Paul Deherain. In 1874 he obtained his doctorate in sciences, and was later appointed professor of botany at the University of Lille (1878). From 1881 to 1887, he was head of the Archives botaniques du nord de la France.In 1878 he became a member of the Société botanique de France.
