French biologist stubs

Jean-Joseph Zéphirin Gerbe (21 December 1810 in Bras – 26 June 1890 in Bras) was a French naturalist. He was the first to discover the pattern of wing taxis, the absence (diastataxis) or presence (eutaxy) of the fifth secondary in birds.He was co-author of Ornithologie européenne, ou Catalogue analytique et raisonné des oiseaux observés en Europe with countryman Côme-Damien Degland (second edition, 1867). He also published a French translation of Alfred Brehm's Illustrirtes Thierleben with the title La vie des animaux illustrée : description populaire du règne animal (4 volumes).Species he described include Gerbe's vole.

Achille Joseph Urbain (9 May 1884 – 5 December 1957) was a French biologist born in Le Havre.

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.

Louis Herbert Manceaux (1865–1934) was a French physician, parasitologist, and co-discover of Toxoplasma gondii with Charles Nicolle in 1908.

Adrien Loir (15 December 1862 – 1941) was a French bacteriologist born in Lyon. He was a nephew of Louis Pasteur, and for much of his career was associated with the Pasteur Institute.
From 1882 to 1888 Loir was an assistant in Pasteur's laboratory in Paris, where he performed research of swine fever. In 1886, he installed the first anti-rabies clinic in Saint Petersburg. Between 1888 and 1893 he made two journeys to Australia to conduct research of anthrax and pleuropneumonia. While there, he investigated the use of chicken cholera bacillus in an attempt to eradicate the country's rabbit infestation.
In 1893 he founded the Pasteur Institute of Tunisia, and for several years was a professor of hygiene and bacteriology at the colonial school in Tunis. In 1906 he traveled to Canada, where he demonstrated that the equine disease, dourine is caused by the parasite trypanosoma equiperdum.

Charles Edouard Chamberland (French pronunciation: [ʃaʁl ʃɑ̃bɛʁlɑ̃]; 12 March 1851 – 2 May 1908) was a French microbiologist from Chilly-le-Vignoble in the department of Jura who worked with Louis Pasteur.

In 1884 he developed a type of filtration known today as the Chamberland filter or Chamberland-Pasteur filter, a device that made use of an unglazed porcelain bar. The filter had pores that were smaller than bacteria, thus making it possible to pass a solution containing bacteria through the filter, and having the bacteria completely removed from the solution. Chamberland was also credited for starting a research project that led to the invention of the autoclave device in 1879.

Raphaël Anatole Émile Blanchard (28 February 1857 – 7 February 1919) was a French physician and naturalist who was a pioneer of medical zoology, with studies on parasites ranging from protozoa to worms and insects.

Blanchard was born in Saint-Christophe-sur-le-Nais. He was a great grand nephew of the balloonist and parachute inventor Jean Pierre Blanchard. He went to study medicine in Paris in 1874. He became interested in zoology and worked at the laboratory at the École des Hautes-Études where he became a histological preparator for Charles Robin and Georges Pouchet, the latter influencing him towards studies on experimental teratology (inducing mutations and malformations). He travelled around Europe in 1877 with a grant from the Paris City Council, studying embryology in Vienna and comparative anatomy in Bonn. He received another grant in 1880 to study the organization of universities and biological education across Europe. He wrote a dissertation on anesthesia induced by nitrous oxide in 1880 under Paul Bert and received a medical degree. He became a professor of natural history at the faculty of medicine in Paris in 1883. In 1884 he also became a professor in the school of anthropology. He taught medical zoology from 1883 to 1887. He became interested in microbiology after studies at the Institut Pasteur in 1896 and took an interest in parasitology. He founded the journal Archives de parasitologie in 1898.In 1889 he served as the secretary general for the 1st International Congress of Zoology in Paris alongside the Universal Exhibition. He was made officer of the Legion of Honor in 1912. Towards the end of his life he studied medical works from the Middle Ages including stone inscriptions.

Francis Hallé (born 15 April 1938) is a French botanist and biologist. He is a specialist on tropical rainforests and of tree architecture. He is best known for the first "Radeau des cimes" ("Navigating the peaks") he initiated with an aerostatic balloon in 1986. He is a Professor Emeritus of the University of Montpellier.In 2010, he and Luc Jacquet started to collaborate for a Wild-Touch film project, La Forêt des pluies, a documentary about primary forests.

Henri-Mamert-Onésime Delafond (13 February 1805 – 15 November 1861) was a French veterinarian born in Saint-Amand-en-Puisaye, Nièvre department. Delafond was one of the primary representatives of veterinary science in France during the first half of the nineteenth century.He served as a professor and director of the Maisons-Alfort veterinary school. He was a member of the Académie de Médecine and of the Société nationale d'agriculture.Delafond is remembered for pioneer microscopic research of Bacillus anthracis, the causative organism of anthrax. Also, with microbiologist David Gruby (1810–1898), he performed extensive investigations of Tritrichomonas suis, a parasite found in swine.
In 1842 with Gabriel Andral (1797–1876) and Jules Gavarret (1809–1890), he was co-author of an important treatise on domestic animal blood composition titled Recherches sur la composition du sang de quelques animaux domestiques, dans l’état de santé et de maladie. With Honoré Bourguignon, he published Traité pratique d'entomologie et de pathologie comparées de la psore ou gale de l'homme et des animaux domestiques (Treatise on the entomology and comparative pathology of scabies affecting humans and domesticated animals).
