Adolfo Ferrata (26 April 1880 in Brescia – 9 March 1946) was an Italian pathologist and hematologist.
In 1904 he earned his medical degree from the University of Parma, spending the following years performing scientific research in clinics at Parma, Berlin and Naples. From 1921 to 1924 he was a professor of special medical pathology at the Universities of Messina and Siena, afterwards serving as a professor of clinical medicine at the University of Pavia, a position he kept for the remainder of his career.Among his contributions to medical science are investigations on the structure and embryology of the kidney, research on the morphology of intestinal villi and haematopoietic studies in normal and pathological conditions. In his research of haematopoiesis, Ferrata helped demonstrate the systemic nature of leukemia, leading him to support an hypothesis that elements of the blood (erythrocytes, leukocytes, and blood platelets) all originate from the hemocytoblast, a direct descendant of a mesenchymal cell, which he referred to as an emoistioblasto (hemohistioblast).In 1907 he was the first scientist to show that the complement could be split into two components that were singularly inactive, only regaining their activity when reunited.In 1920 Ferrata founded the journal "Haematologica".

Clemente Estable (23 May 1894 – 27 October 1976) was a Uruguayan biologist, researcher and professor. Best known for being a pioneer in cellular biology and neurobiology research.
The 'Instituto de Investigaciones Biologicas Clemente Estable' (of which he was a founding member) carries on his scientific work and carries his name.

Theodor Escherich (German pronunciation: [ˈteːodoːɐ̯ ˈʔɛʃəʁɪç]; 29 November 1857 – 15 February 1911) was a German-Austrian pediatrician and a professor at universities in Graz and Vienna. He discovered and described the bacterium Escherichia coli.

Alexander Ellinger (17 April 1870 in Frankfurt am Main – 26 July 1923 in Frankfurt am Main) was a German chemist and pharmacologist.
From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.He is remembered for his extensive biochemical research of several amino acids, especially tryptophan. In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan. His other work included studies on the water exchange between body tissues and blood, on the formation on lymph, and with chemist Karl Spiro, he conducted investigations of blood coagulation.

Prosper Menière (18 June 1799 – 7 February 1862) was a French doctor who first identified that the inner ear could be the source of a condition combining vertigo, hearing loss and tinnitus, which is now known as Ménière's disease.

Ludwig Edinger (13 April 1855 – 26 January 1918) was an influential German anatomist and neurologist and co-founder of the University of Frankfurt. In 1914 he was also appointed the first German professor of neurology.
Edinger was born into a Jewish family and grew up in Worms, where his father was a successful textile salesman and democratic congressman in the state parliament of Hesse-Darmstadt. His mother was the daughter of a physician from Karlsruhe. He was not ashamed that he started his career as a poor man. Indeed, he proposed free schooling for all children in 1873, but without success.
Edinger studied medicine from 1872 to 1877 in Heidelberg and Strasbourg. His studies into neurology began during his time as an assistant physician in Giessen (1877 - 1882). His habilitation was in 1881 about neurological researches. He became a docent for these themes. He worked in Berlin, Leipzig and Paris and opened his own practice for neurology in Frankfurt am Main in 1883.
Due to Edingers initiative in 1885, the pathologist Karl Weigert became director of the Dr. Senckenbergische Anatomie in Frankfurt. Weigert opposed antisemitism. Weigert gave his friend Edinger a place to work in his institute. In 1902, Edinger received enough space to start his own neurological department.
In 1909, after a dispute between Edinger and the Senckenberg foundation about the finances of the neurological institute, Edinger moved to the University of Frankfurt under the condition that he was responsible for the financing of the department. His problems had eased in 1886, when he married Anna Goldschmidt, the daughter of an old family of traditional Jewish bankers in Frankfurt; she received a large inheritance in 1906.
Edinger died suddenly on 26 January 1918 in Frankfurt of a heart attack. He had left instructions for his brain to be examined in his institute. The institute continued with the introduction of a foundation set-up by Edinger. The Neurology department of the Goethe University's Faculty of Medicine is named after him.
Edinger is credited with coining the terms "gnosis" and "praxis". These terms were later used in psychological descriptions of agnosia and apraxia. Also, he was the first to describe the ventral and dorsal spinocerebellar tracts and to distinguish the paleocerebellum from the neocerebellum.

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.

René Dujarric de la Rivière (19 April 1885 – 28 November 1969) was a French microbiologist and hygienist.
He studied medicine in Bordeaux and Lyon, then for several years worked as a medical extern at the Hospitals Necker and Ténon in Paris (1905–10). In 1913 he received his medical doctorate, and in 1929, obtained his doctorate in natural sciences. From 1945 to 1958 he was an assistant director of the Pasteur Institute.In 1918 he demonstrated that influenza was caused by a filterable agent that was in all probability a virus. In the 1920s he performed research of Amanita phalloides (death cap mushroom) in Louis Lapicque's laboratory at the Sorbonne, producing an antitoxic serum (serum antiphallinique) as a result. In 1927, at the Pasteur Institute, he established a center for the study of blood groups.In 1930, with Jules Bordet, he founded the Société Internationale de Microbiologie. He was a member of the Société de biologie (from 1928), the Académie Nationale de Médecine (from 1945, department of hygiene) and in 1951, was appointed president of the Société mycologique de France.

Pierre Étienne Simon Duchartre (27 October 1811, Portiragnes – 5 November 1894, Meudon) was a French botanist.
He studied biology in Toulouse, where after graduation he worked as a teacher. From 1837 he taught classes in Fumel, several years later moving to Paris, where in 1848 he was accepted by the faculty of sciences. During the following year, he was appointed a professor of botany and plant physiology at the Institut agronomique in Versailles. In 1861 he attained the chair of botany at the Sorbonne.In 1854 he was co-founder of the Société Botanique de France, an institution in which he served as president on several separate occasions.In 1850 he experimented with sulfur as a remedy against powdery mildew, a fungus that had a serious negative impact on European grapes during the mid-19th century. The genus Duchartrea (family Gesneriaceae) was named in his honor by botanist Joseph Decaisne. He is the binomial author of many species from the botanical family Aristolochiaceae.

Hermann Dold (born 5 October 1882 in Stuttgart, died 31 October 1962 in Freiburg im Breisgau) was a German physician and bacteriologist.
