In 1903 he earned his medical doctorate from the University of Giessen, afterwards continuing his studies with Eugen Bostroem (1850-1926) in Giessen, under Morris Simmonds (1855-1925) in Hamburg and with Ilya Ilyich Metchnikoff (1845-1916) in Paris. In 1924, he became director of the pathological institute at the University Medical Center Hamburg-Eppendorf.
Fahr is remembered for his work in nephrology and research of kidney disorders. With internist Franz Volhard (1872-1950) he published a comprehensive monograph on Bright's disease titled Die Brightsche Nierenkrankheit. In 1923, he provided an early correlation between lung cancer (Bronchialkarzinom) and tobacco smoking. Today his name is associated with Fahr's disease, which is a degenerative neurological disorder characterized by calcifications and cell loss within the basal ganglia. Fahr was however not the first describe the disease and there are suggestions that the eponym be avoided.In 1933 Fahr signed the Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State. He committed suicide in 1945.

Dr. Rudolph (Rudolf) Emmerich (29 September 1856– 15 November 1914) was a German bacteriologist noted for his advances against cholera and his co-invention of the first antibiotic drug Pyocyanase with Oscar Löw in 1890s.

Emmerich made experiments on himself by injections of cholera strains and proved that cholera is less virulent when contracted from human to human as opposed to from the ground.
Emmerich was professor Hygiene and Bacteriology at the University of Munich.

Léon Dufourmentel (1884 – July 29, 1957) was a French surgeon, son of a merchant, who specialized in maxillofacial surgery, leading to reconstructive surgery. Intern of Hospitals of Paris, then leader of the clinical faculty of medicine of Paris. He was the son-in-law of the anatomist Pierre Sebileau, and the father of plastic surgeon Claude Dufourmentel (Former head of department at the Hôpital Saint-Louis).
During the First World War, he was responsible for caring for gueules cassées (broken faces), and being led to the creation of units of maxillofacial surgery, he found a method for repairing facial wounds: He described a pedicled vascularized flap from the temporal scalp (popularly called a Dufourmentel flap)(http://www.biusante.parisdescartes.fr/1418/cadre2e.htm) and transferred the tissue to the chin area. This tissue transfer was more reliable than a free skin graft. It was his idea to first use prosthetic inclusions prior to 1930 - then implants used were mostly made of ivory, rubber on the nose.

Jean Alexandre Eugène Dieudonné (French: [ʒɑ̃ alɛksɑ̃dʁ øʒɛn djødɔne]; 1 July 1906 – 29 November 1992) was a French mathematician, notable for research in abstract algebra, algebraic geometry, and functional analysis, for close involvement with the Nicolas Bourbaki pseudonymous group and the Éléments de géométrie algébrique project of Alexander Grothendieck, and as a historian of mathematics, particularly in the fields of functional analysis and algebraic topology. His work on the classical groups (the book La Géométrie des groupes classiques was published in 1955), and on formal groups, introducing what now are called Dieudonné modules, had a major effect on those fields.
He was born and brought up in Lille, with a formative stay in England where he was introduced to algebra. In 1924 he was admitted to the École Normale Supérieure, where André Weil was a classmate. He began working in complex analysis. In 1934 he was one of the group of normaliens convened by Weil, which would become 'Bourbaki'.

Marie-Guillaume-Alphonse Devergie (February 15, 1798 – October 2, 1879) was a French dermatologist born in Paris.

Charles Jean Julien Depéret (25 June 1854 – 18 May 1929) was a French geologist and paleontologist. He was a member of the French Academy of Sciences, the Société géologique de France and dean of the Science faculty of Lyon.

In 1888, he became lecturer at Aix-Marseille University, and in 1889 he became professor of geology at the University of Lyon. He died in Lyon.In 1892 he introduced the Burdigalian Stage (Lower Miocene) based on stratigraphic units found near Bordeaux and in the Rhône Valley. He was an advocate of the controversial prehistoric artifacts findings of Glozel. Along with Edward Drinker Cope, his name is associated with the so-called "Cope-Depéret rule", a law which asserts that in population lineages, body size tends to increase over evolutionary time.

Charles-Pierre Denonvilliers (4 February 1808 – 5 July 1872) was a French surgeon who was a native of Paris.
In 1837 he received his medical doctorate, and later was a professor of surgery and anatomy in Paris.Denonvilliers was a pioneer of facial reconstructive surgery. In 1856 he independently performed the second Z-plasty operation for treatment of lower lid ectropion, after Horner in 1837. He is credited for providing the first description of the rectoprostatic fascia, which is sometimes called "Denonvilliers' fascia".
