Claudius Regaud (born 30 January 1870 in Lyons, France; died 29 December 1940 in Couzon-au-Mont-d'Or, France) was a French medical doctor and biologist, one of the pioneers in radiotherapy at the Curie Institute.

Louis Étienne Ravaz or Louis Ravaz (Saint-Romain-de-Jalionas, Isère, 1863 — Montpellier, 1937) was a specialist of ampelography and one of the creators of modern viticulture. In 1892, he founded the grape research station of Cognac (French: Station viticole de Cognac), that he directed for several years. He was professor of viticulture (and from 1919 director) at the National School of Agriculture of Montpellier (École nationale d’agriculture de Montpellier). He contributed to the diffusion of the use of the American varieties in the regions affected by French blight (Phylloxera) and investigated the pathologies of the grapevine. He published several works on viticulture. With Pierre Viala, he described the causes of the black-rot disease of grapevine and founded the "Revue de viticulture".
He was the taxon author of:

Guignardia Viala & Ravaz, Bull. Soc. mycol. Fr. 8: 63 (1892)

August Rauber (March 9, 1841 – February 16, 1917) was a German anatomist and embryologist born in Obermoschel in the Rhineland-Palatinate.
Rauber was born the fourth of five children to Stephan Rauber and Rosalie née Oberlé. He studied medicine in Munich, obtaining his doctorate in 1865. At Munich his instructors included Theodor Bischoff (1807–1882), Nicolaus Rüdinger (1832–1896) and Julius Kollmann (1834–1918).

Paul Theodor Range (1 May 1879 in Lübeck – 29 August 1952 in Lübeck) was a German geologist and naturalist.
He studied natural sciences at the universities of Würzburg and Leipzig, receiving his doctorate in 1903. From 1906 to 1914 he worked as a government geologist in German South-West Africa, and afterwards performed scientific studies in the Sinai Peninsula. From 1921 he gave lectures in geology at the University of Berlin, becoming an associate professor in 1934. In 1936, he was named president of the Deutschen Geologischen Gesellschaft.Range is commemorated in the scientific name of the Namib sand gecko (Pachydactylus rangei), which was described as a species new to science by herpetologist Lars Gabriel Andersson in 1908.

Gaston Ramon (30 September 1886 – 8 June 1963) was a French veterinarian and biologist best known for his role in the treatment of diphtheria and tetanus.
He was born in Bellechaume (Yonne, France) and attended l'École vétérinaire d'Alfort from 1906 to 1910. In 1917 he married Marthe Momont, grandniece of Emile Roux.
During the 1920s, Ramon, along with P. Descombey, made major contributions to the development of effective vaccines for both diphtheria and tetanus. In particular, he developed a method for inactivating the diphtheria toxin and the tetanus toxin using formaldehyde which, in its essentials, is still used in vaccines manufactured today. He also developed a method for determining the potency of the vaccines, an essential element required for the reproducible production of these pharmaceuticals.
He received 155 Nobel Prize Nominations but never received the prize.A collection of his papers is held at the National Library of Medicine in Bethesda, Maryland.

Louis-Joseph Alcide Railliet (also known as Alcide Railliet, born 11 March 1852 at La Neuville-lès-Wasigny in the Ardennes – died 25 December 1930) was a French veterinarian and helminthologist.
Professor at the Veterinary School of Alfort, he is considered one of the founders of modern parasitology and wrote several books of veterinary parasitology. He chaired the Société zoologique de France in 1891. He was a member of the French Académie Nationale de Médecine, from 29 December 1896 to his death. He received the Legion of Honor.

Édouard Ernest Prillieux (11 January 1829 in Paris – 7 October 1915 in Mondoubleau) was a French botanist and agronomist known for his work with plant diseases.
He took courses at the Muséum National d'Histoire Naturelle as a pupil of Adrien-Henri de Jussieu and Adolphe-Théodore Brongniart, then from 1850 studied botany at the Institut national agronomique in Versailles under Pierre Étienne Simon Duchartre. For a number of years afterwards he served in various functions at the Sorbonne and at the natural history museum. From 1874 he taught classes at the École Centrale des Arts et Manufactures, and in 1876 was named a professor of botany and plant physiology at the agronomic institute. In 1887 he became director of the Station de Pathologie végétale in Paris.In 1876 he was chosen as president of the Société nationale d'agriculture, and in 1883 became inspector general of agricultural education. In 1897 he replaced Charles Victor Naudin at the French Academy of Sciences (botanical section). From 1897 to 1906 he served as a senator representing the department of Loir-et-Cher.The mycological genera Prillieuxia (Sacc. & Syd., 1899) and Prillieuxina (G.Arnaud, 1918) commemorate his name.

André-Romain Prévot (born in Douai, Nord on 22 July 1894, died in Clamart, Hauts-de-Seine on 21 November 1982) was a French bacteriologist. He authored a classification of bacteria, gave his name to a genus of Gram-negative bacteria, prevotella, and created in 1978 the médaille Pasteur of Académie des Sciences of France.
In 1914 as the war starts, he was assigned as an auxiliary physician in Infanterie; he knew the life in the trenches, the murderous battles of the Chemin des Dames, the hell of Verdun where his heroic conduct earned him the Croix de Guerre. This constant communion with suffering and death will influence his taste and direct him towards the medicine to which he will devote himself.
After the armistice he will be released and evacuated to Denmark, where the exchange of medical prisoners takes place. It was there that he met a medical student, Anna Sorensen, whom he married in 1919. They will stay together all their lives and have four children.
He was elected member of Académie des Sciences on 28 January 1963, member of IVe Section de l'Académie Nationale de Médecine in 1966, Officier de la Légion d'Honneur and Grand Officier du Mérite National.

Félix-Archimède Pouchet (26 August 1800 – 6 December 1872) was a French naturalist and a leading proponent of spontaneous generation of life from non-living materials, and as such an opponent of Louis Pasteur's germ theory. He was the father of Georges Pouchet (1833–1894), a professor of comparative anatomy.
From 1828 he was director of the Rouen Jardin des Plantes. Later, in 1838, he became professor at the School of Medicine at the University of Rouen. His major scientific work Hétérogénie was published in 1859. He also wrote a layperson's encyclopedia The Universe, published in 1870, which gives an overview of the sciences, but in which Pouchet ridicules Louis Pasteur's theories (calling them panspermism) and atomic theory.
In 1847, Pouchet effectively launched the study of the physiology of cytology. In 1848, he was elected as a member to the American Philosophical Society.

Nicolas Auguste Pomel (20 September 1821 – 2 August 1898) was a French geologist, paleontologist and botanist. He worked as a mines engineer in Algeria and became a specialist in north African vertebrate fossils. He was Senator of Algeria for Oran from 1876 to 1882.
