French mycologists

Jean Paul Vuillemin (13 February 1861 – 25 September 1932 in Malzéville) was a French mycologist born in Docelles.
He studied at the University of Nancy, earning his medical doctorate in 1884. In 1892 he obtained his doctorate in sciences at the Sorbonne, and from 1895 to 1932 he was a professor of natural history at the medical faculty in Nancy.He described the genera Spinalia and Zygorhynchus. The mushroom genus Vuilleminia (Maire) is named after him.
In 1889 he employed the term "antibiotic" when describing the substance pyocyanin.In 1901 he transferred the yeast-like fungus that was named Saccharomyces hominis by Otto Busse and Saccharomyces neoformans by Francesco Sanfelice to the genus Cryptococcus due to its absence of ascospores. The French Academy of Sciences awarded him the Prix Montagne for 1902.In 1912 Vuillemin created the genus Beauveria to honor Jean Beauverie for his work the previous year on the type species - B. bassiana - transferring it from Botrytis.

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)

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.

Louis Alexandre Mangin (8 September 1852, in Paris – 27 January 1937) was a French botanist and mycologist.
In 1873, he became an associate professor at the Lycée de Nancy, followed by a professorship at the Lycée Louis-le-Grand in Paris (1881–1904). During this time frame, he was also a lecturer on natural sciences at the Sorbonne (from 1890). From 1904 to 1931, he was a professor (Chaire de cryptogamie) at the Muséum national d'histoire naturelle, and was director of the museum from 1919 until his retirement in 1931. For several years he was director of the menagerie at the Jardin des Plantes (1920 to 1926).
Mangin was a member of the Académie des sciences, the Académie d'agriculture de France, the Académie des sciences coloniales and the Société mycologique de France.
His early research dealt largely with plant anatomy and physiology; his doctoral thesis involving the adventitious roots of monocotyledons. With Gaston Bonnier (1853–1922), he performed extensive research of plant respiration, transpiration and carbon assimilation. In the early 1890s he is credited with the discovery of callose, a fundamental substance found in the cell membrane of plants.

René Charles Joseph Ernest Maire (29 May 1878, Lons-le-Saunier – 24 November 1949) was a French botanist and mycologist. His major work was the Flore de l'Afrique du Nord in 16 volumes published posthumously in 1953. He collected plants from Algeria, Morocco, France, and Mali for the herbarium of the National Botanic Garden of Belgium.

René Dujarric de la Rivière (19 April 1885 – 28 November 1969) was a French microbiologist and hygienist.
He studied medicine in Bordeaux and Lyon, then for several years worked as a medical extern at the Hospitals Necker and Ténon in Paris (1905–10). In 1913 he received his medical doctorate, and in 1929, obtained his doctorate in natural sciences. From 1945 to 1958 he was an assistant director of the Pasteur Institute.In 1918 he demonstrated that influenza was caused by a filterable agent that was in all probability a virus. In the 1920s he performed research of Amanita phalloides (death cap mushroom) in Louis Lapicque's laboratory at the Sorbonne, producing an antitoxic serum (serum antiphallinique) as a result. In 1927, at the Pasteur Institute, he established a center for the study of blood groups.In 1930, with Jules Bordet, he founded the Société Internationale de Microbiologie. He was a member of the Société de biologie (from 1928), the Académie Nationale de Médecine (from 1945, department of hygiene) and in 1951, was appointed president of the Société mycologique de France.
