Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described.
Ernst Ludwig Bresslau (10 July 1877, Berlin – 9 May 1935, São Paulo) was a German zoologist. He was the son of historian Harry Bresslau.
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.
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French naturalist and explorer.
From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey.
They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest.
The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet, but was prevented by a severe attack of fever.
Grandidier travelled to Zanzibar to recuperate, remaining some time and making important collections and publishing an account of his findings. He then visited the island of Réunion and in 1865 made his first visit to Madagascar. He became devoted to the study of the island, revisiting in 1866 and 1868. He finally returned permanently to France in 1870. During his explorations he crossed the island three times, travelling 3000 kilometers in the interior and 2500 along the coast. He made observations which resulted in the production of a map of the island used in future expeditions.
After returning to France he began to work on his great work, L'Histoire physique, naturelle et politique de Madagascar. This work was undertaken in cooperation with others such as Alphonse Milne-Edwards and Leon Vaillant. This work ran to 40 volumes, the final volumes published posthumously by his son Guillaume Grandidier. He described about 50 new species of reptiles and amphibians.Alfred Grandidier's work drew the attention of the French government to Madagascar, which it would annex at the end of 1890.
He was elected to the French Academy of Sciences in 1885 and was the president of the French Geographical Society from 1901 to 1905. The Royal Geographical Society awarded him their Founder's Medal in 1906.
Auguste Henri André Duméril (30 November 1812 – 12 November 1870) was a French zoologist. His father, André Marie Constant Duméril (1774–1860), was also a zoologist. In 1869 he was elected as a member of the Académie des sciences.
Duméril studied at the University of Paris, and in 1844 became an associate professor of comparative physiology at the university. From 1857, he was a professor of herpetology and ichthyology at the Muséum National d'Histoire Naturelle in Paris.
In 1851, with his father, he published Catalogue méthodique de la collection des Reptiles. With zoologist Marie Firmin Bocourt (1819–1904), he collaborated on a project called Mission scientifique au Mexique et dans l'Amérique Centrale, a publication that was the result of Bocourt's scientific expedition to Mexico and Central America from 1864 to 1866. The section on reptiles is considered to be Dumeril's best written effort in the field of herpetology. Duméril died in 1870 during the siege of Paris, and Mission scientifique au Mexique et dans l'Amérique Centrale was continued by Bocourt, Léon Vaillant (1834–1914) and other scientists.
As part of the Collection des Suites à Buffon, he issued a two-volume ichthyological study titled Histoire naturelle des poissons, ou Ichtyologie générale (1865, 1870), research that complemented the works of Georges Cuvier (1769–1832) and Achille Valenciennes (1794–1865) by describing species not covered by the two famous naturalists. Duméril also conducted significant research involving the axolotl (Ambystoma mexicanum).
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.
Joseph Paul Gaimard (31 January 1793 – 10 December 1858) was a French naval surgeon and naturalist.
Alfred Edmund Brehm (German pronunciation: [ˈalfʁeːt ˈʔɛtmʊnt ˈbʁeːm]; 2 February 1829 – 11 November 1884) was a German zoologist, writer, director of zoological gardens and the son of Christian Ludwig Brehm, a famous pastor and ornithologist.
Through the book title Brehms Tierleben, which he co-authored with Eduard Pechuël-Loesche, Wilhelm Haacke, and Richard Schmidtlein, his name became a household word for popular zoological literature.
