Ernst von Herzog (23 November 1834, Esslingen am Neckar – 16 November 1911) was a German classical philologist and archaeologist, who as an expert in the field of Roman epigraphy.
He studied theology and classical philology at the University of Tübingen, and afterwards continued his education at the University of Munich. From 1857 he worked as a tutor in Paris, then studied archaeology at Berlin, followed by research at the German Archaeological Institute in Rome. In 1861 he conducted studies of ancient Roman inscriptions in southern France. In 1862 he obtained his habilitation for classical philology at Tübingen, where in 1867 he became an associate professor, followed by a full professorship in classical philology in 1874. Herzog was a prominent member of the Reichs-Limeskommission (German Limes Commission) and of the Römisch-Germanische Kommission des Deutschen Archäologischen Instituts (Roman-Germanic Commission of the German Archaeological Institute).As a result of his scientific research in France, he published a book on the history of Gallia Narbonensis titled "Galliae narbonensi Commis provinciae Romanae historia descriptio institutorum expositio" (1864). In his studies associated with Limes Germanicus, he conducted archaeological excavations at several sites in Württemberg — Rottenburg am Neckar (1883–84), near Öhringen (1892), and Mainhardt and Jagsthausen (1893).He was the author of a well-received work on the history and structure of the Roman Constitution, titled "Geschichte und system der Römischen Staatsverfassung" (2 volumes; 1884, 1891). In 1871 he published "Untersuchungen über die bildungsgeschichte der griechischen und lateinischen sprache" (Studies on the educational history of Greek and Latin languages).

Erna Dorothea Luise Sack (née Weber; 6 February 1898 – 2 March 1972) was a German lyric coloratura soprano, known as the German Nightingale for her high vocal range.

Melchior Treub (26 December 1851 – 3 October 1910) was a Dutch botanist. He worked at the Bogor Botanical Gardens in Buitenzorg on the island of Java, south of Batavia, Dutch East Indies, gaining renown for his work on tropical flora. He also founded the Bogor Agricultural Institute. He traveled and collected across many areas of Southeast Asia.
He was born in Voorschoten, and in 1873 he graduated in biology from the University of Leiden. Subsequently, he remained in Leiden as a botanical assistant. From 1880 to 1909 he was a botanist based in the Dutch East Indies.
In 1879 he was appointed a member of the Royal Dutch Academy of Sciences (KNAW) and was appointed as director of Bogor Botanical Gardens' Lands Plantentuin in Buitenzorg (Bogor) in the year 1880. Treub worked on tropical flora on Java and organized the Botanical Garden as a world-renowned scientific institution of botany. Under his leadership many crucial researches were successfully completed on plant diseases of economic crops.
In 1903 he established the Buitenzorg Landbouw Hogeschool, a school that later evolved into the Bogor Agricultural Institute. In 1905 he became director of the newly established Department of Agriculture in the Dutch East Indies. In 1907 Treub was the recipient of the Linnean Medal for his outstanding achievements in sciences. The Dutch "Society for the Promotion of the Physical Exploration of the Dutch Colonies" is sometimes referred to as the Treub Maatschappij.
As a botanical collector, he travelled throughout the Indies, and to the Philippines, Sri Lanka, Singapore and Penang. He was interested in plant morphology and physiology, and published treatises on the morphology of Balanophoraceae, Loranthaceae and Lycopodiaceae. He is credited for coining the term "protocorm" to describe the early stages in the germination of lycopods.He worked for nearly 30 years at the gardens before returning to the Netherlands in 1909 due to his worsening health. Dr. Treub then settled on the village of Saint-Raphael on French Riviera, where he died in 1910.

Pierre-Marie Termier (3 July 1859 – 23 October 1930) was a French geologist.

He was born in Lyon, in Rhône, France, the son of Joseph François Termier and Jeanne Mollard. At the age of 18 he entered the Polytechnic School, then the Paris School of Mines in 1880. After graduation, he became professor at the school of mines at Saint-Etienne. In 1894 he left for Paris, where he would teach for the remainder of his career.
He was elected as a member of the French Academy of Sciences in 1909, in the mineralogy section. Two years later he became the director of the French geological cartography service. In 1930 he became vice-president of the Academy.
During his career he performed geological studies of the Alps, as well as Corsica and North Africa. He was a proponent of the nappe concept and of tectonics as a mountain-building force.
The wrinkle ridge Dorsum Termier on the Moon is named after him.

Ernest Saint-Charles Cosson (22 July 1819 – 31 December 1889) was a French botanist born in Paris.
Cosson is known for his botanical research in North Africa, and during his career he participated in eight trips to Algeria. In several of these he was accompanied by Henri-René Le Tourneux de la Perraudière (1831–1861), whom he honoured in the naming of several species and genera (e.g., Perralderia, Galium perralderii). In 1863 he was elected president of the Société botanique de France, and from 1873 to 1889, he was a member of the Académie des sciences.In 1882 Jules Ferry, as Minister of Public Instruction, decided to create a mission to explore the Regency of Tunisia.
The expedition was headed by Cosson and included the botanist Napoléon Doumet-Adanson and other naturalists.
In 1884 a geological section under Georges Rolland was added to the Tunisian Scientific Exploration Mission.
Rolland was assisted by Philippe Thomas from 1885 and by Georges Le Mesle in 1887.With Jacques Nicolas Ernest Germain de Saint-Pierre (1815–1882), Cosson published the influential Atlas de la Flore des Environs de Paris.Botanical specimens collected by Cosson are held in many herbaria around the world, including the National Museum of Natural History, France, Harvard University Herbaria, the herbarium at the Royal Botanic Gardens, Kew, the National Herbarium of Victoria at the Royal Botanic Gardens Victoria, Copenhagen University Botanical Museum, the New York Botanical Garden, and the Komarov Botanical Institute, among others.

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.

Robert William Schmieder (born July 10, 1941) is an American scientist and explorer. Schmieder has had a multidisciplinary career, broadly divided between physics and related physical sciences, and natural science and exploration. In most of his projects, he created and led teams of both professional scientists and volunteers. His work is documented in about 100 technical publications and 10 books. Among his most significant work was the invention of laser spark spectroscopy (now commercialized), the formulation of nanologic (the use of nanoscale devices in computers), and the concept of underwater islands (which led to designation of the Cordell Bank National Marine Sanctuary).

Jane Hading (25 November 1859 – 28 February 1941) was a French actress. Her real name was Jeanne-Alfrédine Tréfouret.
