Louis-Félix Henneguy (18 March 1850 – 16 January 1928) was a French zoologist and embryologist born in Paris.
In 1875, he received his medical doctorate from the University of Montpellier with a dissertation on the physiological action of poisons, Étude physiologique sur l'action des poisons. In 1883 he obtained his agrégation with Les lichens utiles, a thesis on useful lichens.
During his career he was a professor of comparative embryology at the Collège de France (1900–28), and a member of the Académie de Médecine, the Académie d'Agriculture and the Académie des sciences (1908–28). From 1894 he was director of the journal, Archives d'anatomie microscopique.
He is known for his extensive research of phylloxera, publishing a number of papers on means of destroying its eggs during the winter (1885, 1887–88). Also he performed studies on the natural history of the apple blossom weevil, proposing methods for its eradication (1891). On behalf of the Marine Fisheries Advisory Committee, he did reviews involving the sale and consumption of mussels throughout the year.
With Hungarian neuroanatomist, Mihály Lenhossék (1863–1937), the "Henneguy–Lenhossek theory" is named, which states the claim that mitotic centrioles and ciliary basal kinetosomes are fundamentally the same structure.As a taxonomist he circumscribed the apicomplexan genus Rhytidocystis, and the protozoan genera Thelohania and Fabrea. The genus Henneguya Thélohan, 1892 is named after him, as are the species Apherusa henneguyi Chevreux & Fage, 1925 and Ectinosoma henneguyi Labbé, 1926.In 1903 he was appointed president of the Société entomologique de France.

Lucien Leon Hauman-Merck (8 July 1880, in Ixelles – 16 September 1965, in Brussels) was a Belgian botanist, who studied and collected plants in South America and Africa.
He received his education in Gembloux, and afterwards relocated to Argentina, where he obtained a position in the department of agronomy and veterinary medicine at the University of Buenos Aires. From 1904 to 1925 he taught classes in botany, plant pathology and agricultural microbiology at the university. In 1910 he laid the foundations for its botanical garden.In Argentina he conducted important phytogeographical research, and he also performed plant collection duties that involved excursions to Paraguay, Chile and Uruguay. In 1927 he returned to Europe, where from 1928 to 1949, he served as a professor of botany at the Free University of Brussels. During this time period, he studied African flora, about which, he collected numerous plants in the Belgian Congo. In 1949 he returned to Argentina as an honorary professor at the University of Buenos Aires. The "Jardín Botánico Lucien Hauman" at the university is named in his honor.The genera Haumania (J.Léonard, 1949) and Haumaniastrum (P.A.Duvign. et Plancke, 1959) commemorate his name, as do species with the epithet of haumanii.

Carl (or Karl) Otto Harz (28 November 1842 in Gammertingen – 5 December 1906 in Munich) was a German mycologist, pharmacist and botanist.
After spending time as an intern in several pharmacies, he studied botany at the University of Berlin. Later, he relocated to Munich, where he served as a lecturer at the Technische Universität München (from 1873) and at the Tierärztlichen Hochschule (from 1874). In 1880 he was appointed professor of botany and pharmacognosy at the Tierärztlichen Hochschule.In 1877, with pathologist Otto Bollinger, he conducted early studies of actinomycosis in cattle, and is credited for naming the causal agent Actinomyces bovis. From his observations, he believed the culprit to be a mould, related to the genera Botrytis or Monosporium.As a taxonomist, he circumscribed a number of varieties from the species Cucurbita pepo. His name is associated with the following mycological genera:

Harzia (family Ceratostomataceae), named by Julien Noël Costantin (1888).
Harziella (family Chaetomiaceae), named by Otto Kuntze (1891).

Dr. Édouard Marie Heckel (March 24, 1843 – January 20, 1916) was a French botanist and medical doctor, and director of the Jardin botanique E.M. Heckel in Marseille.
Heckel was born in Toulon, studied pharmacy and medicine, and in 1861 visited the Caribbean and Australia. In 1875, he was appointed professor in the faculty of sciences at Marseille, and in 1877 professor of medicine. He became a professor of natural history in Nancy in 1878, and is known for his studies of tropical plants and their use as medicinal plants and oilseeds.
From 1885, Heckel turned to the study of tropical plants such as medicinal or industrial oilseeds. In 1893 he founded the Colonial Institute and Museum of Marseille and creates a tropical pathology professorship at the medical school.
In 1887, he won the Prix Barbier from the French Academy of Sciences.In 1896, French botanist Jean Baptiste Louis Pierre named a genus of flowering plants (belonging to the family Meliaceae) from western central Tropical Africa, Heckeldora in his honour.In 1901, he launched the idea of creating an exhibition devoted exclusively to French colonies. This project would be supported by Jules Charles-Roux, who would become the Commissioner General while Heckel was his deputy. The exhibition was held at Parc Chanot in Marseille and was a great success from its opening on April 14, 1906 to its closure Nov. 18, 1906.

Icilio Guareschi (24 December 1847 – 20 June 1918) was an Italian chemist.
Icilio Guareschi studied at the University of Bologna and received his Ph.D there in 1871. He became professor at the University of Siena and in 1879 at the University of Turin, where he worked until his death in 1918.
Guareschi worked in the field of organic chemistry, pharmacy, toxicology and the history and chemistry. In 1894 he discovered a reaction to synthesise 2-Pyridones, today known as the Guareschi-Thorpe condensation.

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.

François Cyrille Grand'Eury (9 March 1839, Houdreville – 22 July 1917, Malzéville) was a French geologist, paleontologist and mathematics teacher.
He studied at the École Loritz in Nancy and at the École des mines in Saint-Étienne, and later worked as a mining engineer in Roche-la-Molière. From 1863 to 1899 he taught classes in mathematics at the École des mines in Saint-Étienne, where in 1883 he received the title of professor.From 1877 he was a member of the Société géologique de France and in 1885 was elected a correspondent member of the Académie des Sciences.He is remembered for his stratigraphic research of coal fields and for his investigations involving the formation of coal. He is credited with establishing the chronological succession of floras associated with the coal seams of the Stephanian stage (named after the development of this stage at Saint-Étienne). He conducted exhaustive studies of coal flora (Cordaites, Calamites, et al), and in 1877 described the genus Tubiculites.

Dominique Alexandre Godron (25 March 1807 - 16 August 1880) was a French physician, botanist, geologist and speleologist born in the town of Hayange, in the département Moselle.
Godron studied medicine at the University of Strasbourg, and during his career distinguished himself in natural sciences as well as in the field of medicine. In 1854 he became dean and professor of natural history to the Faculty of Sciences at Nancy. Here he established a natural history museum and reorganized its botanical garden (now the Jardin Dominique Alexandre Godron, renamed in his honor).
Among his numerous writings were a publication on the flora of the Lorraine region of France called "Flore de Lorraine" (1843), and the three-volume "Flore de France", a work on flora native to France and Corsica that was co-written with botanist Jean Charles Marie Grenier (1808-1875). In addition to his botanical works, he published a number of studies in the field of ethnology.Before Mendel, he discovered the main features of hybridation. In "de l'Espece et des races dans les êtres organises" he also demonstrated that hybridization in the vegetal world was, against the dominant thinking at the time, similar to hybridization in the animal world. He finally demonstrated the unity of mankind in his book dedicated to our species.
In 1846, he was honoured by botanists Jean Baptiste Mougeot and Joseph Henri Léveillé who named Godronia, which is a genus of fungi in the family Helotiaceae. Then in 1927, William Webster Diehl and Edith Katherine Cash published Godroniopsis, which is also a genus of fungi in the family Helotiaceae.

Adriano Fiori (17 December 1865, Casinalbo – 5 November 1950, Casinalbo) was an Italian botanist.
He studied medicine and natural sciences at the University of Modena, then spent several years working as an assistant at the botanical institute in Padua (1892–1900). From 1900 to 1913 he was a professor of natural sciences at the Forestry Institute of Vallombrosa, and from 1913 to 1936, he served as a professor in Florence.During his career, he travelled extensively throughout Italy, during which, he studied and collected many plant specimens. He also spent considerable time botanizing in the Italian colony of Eritrea. He donated tens of thousands of specimens to the herbarium in Florence that included 1300 items from Eritrea.

Joseph Duval-Jouve (7 August 1810 – 25 August 1883) was a French botanist born in Boissy-Lamberville. He was the father of histologist Mathias-Marie Duval (1844-1907).
He taught classes at the college in Grasse (1832–52), afterwards serving as an academic inspector in Algiers, Strasbourg and Montpellier. A portion of his herbarium was donated to the faculty of sciences at Montpellier.
He specialized in research of the family Poaceae and the genus Equisetum. The plant genus Jouvea is named in his honor. He is the taxonomic authority for the grass genus Loretia.
