He served as a military surgeon during the Franco-Prussian War, and a few years later worked in the department of Pierre Potain (1825–1901) at the Hôpital Necker in Paris.

In 1885 he was appointed head of the department of medicine at Hôpital Necker, a position he maintained for the rest of his career.
In 1897 Rendu was elected to the Académie Nationale de Médecine. He was a prolific writer, with many of his medical articles being published in the Bulletin de la Société anatomique de Paris, of which he was its editor in 1873–74. Throughout his career he held an avid interest in natural sciences, and spent considerable time as a botanical collector.

Eduard Müller (4 January 1876, in Annweiler am Trifels – 30 December 1928, in Marburg) was a German internist and neurologist.
He studied medicine at several German universities, receiving his doctorate from the University of Erlangen in 1898.

He is remembered for his work in the field of microbiology. With Joaquín Albarrán (1860–1912) he performed a series of tests in an attempt to find an antidote to the colon bacillus. Eventually the two scientists developed a vaccine that achieved a high degree of immunity in dogs and rabbits. In 1912 with biologist Edouard Dujardin-Beaumetz (1868–1947), he studied the effects of bubonic plague in two Alpine marmots during hibernation. Reportedly, the marmots were able to survive 61 and 115 days after being injected with the disease.In 1911 Mosny reported the first successful embolectomy, a direct arterial surgical procedure that was performed on the femoral artery.

Augustin Marie Morvan (7 February 1819 in Lannilis – 20 March 1897 in Douarnenez) was a French physician, politician, and writer. He is best known for treating the first recorded case of the eponymous Morvan's syndrome, a rare neurological disorder marked by acute insomnia. Morvan served as a deputy to the French National Assembly that inaugurated the Third Republic in 1871. In Brest, France, where he began his medical studies, the Rue Augustin Morvan and the Hôpital Augustin Morvan are named after him.

He studied at the Universities of Würzburg and Zurich, and in 1866 served as a military physician in the Austro-Prussian War. From 1868 to 1870 he was an assistant to Johann Friedrich Horner (1831–1886) at the University Eye Clinic in Zurich. During the Franco-Prussian War (1870–71), he again served as a military doctor, and afterwards worked with Gustav Schwalbe (1844–1916) at Carl Ludwig's Physiological Institute in Leipzig.
In 1872 he earned his habilitation in Leipzig, and subsequently became an associate professor of ophthalmology at the University of Erlangen, where in 1874 he gained a full professorship. In 1879 he was named successor to Robert von Welz at the ophthalmology clinic in Würzburg, and later on, he was a replacement for Karl Ernst Theodor Schweigger at the University of Berlin (1900).
Michel is remembered for work involving tuberculosis of the eye, and his pioneer research of central retinal vein occlusion.Among his written efforts are Lehrbuch der Augenheilkunde (Textbook of ophthalmology, 1890) and Klinischer Leitfaden der Augenheilkunde (Guide to clinical ophthalmology). With Hermann Kuhnt (1850–1925), he founded the journal Zeitschrift für Augenheilkunde.

Karl Mellinger (26 November 1858, in Mainz – 21 May 1917, in Basel) was a German-Swiss ophthalmologist.

Henri Meige (11 February 1866 – 29 September 1940) was a French neurologist born in Moulins-sur-Allier. He characterized Meige's syndrome in 1910.He studied medicine in Paris under Jean Charcot (1825–1893), earning his doctorate in 1893. Afterwards he worked at the Salpêtrière and the École des Beaux-Arts, where in the 1920s he was appointed professor.
With Édouard Brissaud (1852–1909) he researched skeletal changes in acromegaly, concluding that gigantism in adolescents is fundamentally the same disease as acromegaly in adults. During World War I he conducted studies of neuropathy with Pierre Marie (1853–1940).
Meige is best known for his work with extrapyramidal lesions. In 1902, with Eugene Feindel, he published an important work on motor disturbances, blepharospasms and tics. In contrast to Charcot, Meige asserted that disturbances of the extrapyramidal system were manifestations of pathological changes outside the pyramidal system.He was editor of the journals Nouvelle iconographie de la Salpêtrière and Schriftleiter of the Revue Neurologique.
