Alexandre Joseph Émile Brumpt (10 March 1877, in Paris – 8 July 1951) was a French parasitologist.He studied zoology and parasitology in Paris, obtaining his degree in science in 1901, and his medical doctorate in 1906. In 1919 he succeeded Raphaël Blanchard (1857-1919) as professor of parasitology to the Faculté de Médecine de Paris, a position he maintained until 1948. Much of his career was spent performing research in Africa and Latin America.
Brumpt is credited for introducing a technique known as xenodiagnosis into parasitological research. In 1935, he described Plasmodium gallinaceum, an avian malarial parasite that infects chickens and other fowl. He also conducted important research involving the African tsetse fly (Glossina palpalis) as a biological vector for trypanosomiasis. In addition, he did extensive studies of the diseases: schistosomiasis, Chagas disease, onchocerciasis and leishmaniasis.
He described Blastocystis hominis and Entamoeba dispar. The latter species helped to explain why most people who appeared to be infected with Entamoeba histolytica were asymptomatic. However, because there are no morphological differences between the two species, his proposal was largely ignored for over 50 years before being proven correct using molecular techniques.The French Academy of Sciences awarded him the Prix Savigny for 1910. A number of parasitic species bear his name, including Plasmodium brumpti and Xenocoeloma brumpti. Also, a genus of phlebotomine sand flies, Brumptomyia, and a species of Corsican mosquito, Culex brumpti, are named after him.
Brumpt's best known written work is Précis de Parasitologie, which was published in six editions between 1910 and 1949. He was the author of many scientific papers, including several on the Anopheles mosquito and its relationship to malaria. He was the President of the Société zoologique de France in 1922. With Maurice Neveu-Lemaire and Maurice Langeron, he founded in 1923 the parasitological journal Annales de Parasitologie Humaine et Comparée, now continued as Parasite.

Julius Oscar Brefeld (19 August 1839 – 12 January 1925), usually just Oscar Brefeld, was a German botanist and mycologist.

Eugène Louis Bouvier (9 April 1856 in Saint-Laurent-en-Grandvaux – 14 January 1944 in Paris) was a French entomologist and carcinologist. Bouvier was a professor at the Muséum national d'histoire naturelle.

Jean-Baptiste Édouard Bornet (September 2, 1828, Guérigny – December 18, 1911, Paris) was a French botanist. The standard author abbreviation Bornet is used to indicate this person as the author when citing a botanical name.

Rudolf Albert Martin Boehm (Böhm) (19 May 1844, in Nördlingen – 19 August 1926, in Bad Kohlgrub) was a German pharmacologist, known for his work in the field of experimental pharmacology.
He studied medicine at the universities of Munich and Würzburg, and in 1868–70 served as an assistant to Franz von Rinecker at the Juliusspital in Würzburg. In 1871 he obtained his habilitation under Adolf Fick, then during the following year was named a professor of pharmacology, dietetics and history of medicine at the University of Dorpat. Later on, he worked as professor of pharmacology at the universities of Marburg (from 1881) and Leipzig (from 1884), where on four separate occasions he was named dean to the medical faculty. During his tenure at Leipzig, he oversaw the construction of its pharmacological institute (1886–88). Today the institute at Leipzig is known as the Rudolf-Boehm-Institut für Pharmakologie und Toxikologie.
His main research dealt with the pharmacological and toxicological properties of substances of plant origin and their effect(s) on the animal organism. He conducted extensive studies on the actions of digitalis, muscarine (a product of certain mushrooms), choline and curare. In 1895 he classified curare into three groups; "calabash curares" (usually taken from the family Loganiaceae, Strychnos species), "tubo curares" (derived from the family Menispermaceae) and "pot curares" (mixed Menispermaceae and Loganiaceae substances). He also performed significant research of carbohydrate metabolism.

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.

Karl Beurlen (17 April 1901 – 27 December 1985) was a German paleontologist.Beurlen was born in Aalen. He attended University of Tübingen. He completed a PhD in 1923.Beurlen was a proponent of orthogenesis and saltational evolution. He used the term metakinesis (coined by Otto Jaekel) to describe sudden changes of development in organisms. He also invented the term palingenesis as a mechanism for his orthogenetic theory of evolution.He was an assistant of Edwin Hennig.He was a proponent of National Socialist ideology and wrote about the Aryan race.He was director of the Zoologische Staatssammlung München.

Gabriel Bertrand (born 17 May 1867 in Paris, died 20 June 1962 in Paris) was a French pharmacologist, biochemist and bacteriologist.
Bertrand introduced into biochemistry both the term “oxidase” and the concept of trace elements.
The laccase, a polyphenol oxidase and an enzyme oxidating urishiol and laccol obtained from the lacquer tree, was first studied by Gabriel Bertrand in 1894.Bertrand's rule refers to the fact that the dose–response curve for many micronutrients is non-monotonic, having an initial stage of increasing benefits with increased intake, followed by increasing costs as excesses become toxic. In 2005, Raubenheimer et al. fed excess carbohydrates to Spodoptera littoralis and extended Bertrand's rule to macronutrients.In 1894, with Césaire Phisalix, he developed an antivenom for use against snake bites.Bertrand was made a member of the Académie Nationale de Médecine in 1931. In 1932 he became foreign member of the Royal Netherlands Academy of Arts and Sciences.

Pierre-Joseph van Beneden FRS FRSE FGS FZS (19 December 1809 – 8 January 1894) was a Belgian zoologist and paleontologist.

Hermann Beitzke (21 June 1875 – 8 June 1953) was a German pathologist born in Tecklenburg, Westphalia.
Beitzke studied medicine at several universities, earning his doctorate in 1899 from the University of Kiel. In 1900-01 he was an assistant at the institute of hygiene in Halle an der Saale, and afterwards worked at the pathology institutes in Göttingen and Berlin. In 1911 he became a professor at the University of Lausanne, and in 1922 relocated to the University of Graz, where he taught classes until 1941.
He specialized in pathological investigations of infectious diseases, in particular tuberculosis studies. He was co-editor of Ergebnisse der gesamten Tuberkuloseforschung, a journal involving tuberculosis research.
