Marcel Lermoyez (24 July 1858 – 1 February 1929) was a French otolaryngologist and surgeon who was a native of Cambrai.

Jacques Raphaël Lépine (6 July 1840 – 17 November 1919) was a French physiologist who was a native of Lyon.

Clément Georges Lemoine (16 January 1841 in Tonnerre – 13 November 1922 in Paris) was a French chemist and hydrologist. He was the father of geologist Paul Lemoine (1878–1940).
He studied at the École Polytechnique and the École des ponts et chaussées, obtaining a doctorate in physical sciences in 1865. For many years he was associated with the École Polytechnique in Paris, where he ultimately served as a professor of chemistry from 1898 to 1911.In 1866 he began work as an engineer in charge of hydrometric services in the Seine Basin. In 1881 he was appointed chief engineer of bridges and roads, and in 1901, was named inspector general of bridges and roads. He is credited with organizing a flood warning service throughout France.As a chemist he discovered phosphorus sesquisulfide, a compound that will later be used in the manufacture of matches. He continued research on the allotropic transformation of phosphorus, and was also the author of works on chemical equilibria.In 1899 he became a member of the Académie des sciences (chemistry section), of which in 1921, he was named its president.

Hermann Kümmell (22 May 1852, Korbach, Waldeck-Pyrmont – 19 February 1937) was a German surgeon.
In 1875, he received his medical doctorate at Berlin, later working as an assistant physician to Max Schede (1833-1902) at the municipal hospital in Friedrichshain. In 1883 he became chief physician of the surgical department at the "Marienkrankenhaus" in Hamburg, and in 1895 was appointed surgeon-in-chief of the Allgemeinen Krankenhaus Hamburg-Eppendorf. In 1907 he became a titled professor, and in 1919 was a professor of surgery at the University of Hamburg.
Kümmell's work involved the treatment of fractures, bone implants and diseases of the spinal column. He also conducted extensive research of bladder and kidney disturbances, diseases of the chest, et al. He was among the first surgeons to advocate removal of the appendix in cases of recurrent appendicitis, and in 1886 attempted the first choledochotomy.
Among his numerous publications on surgery was Chirurgische Operationslehre, a three-volume work that he co-authored with August Bier (1861-1949) and Heinrich Friedrich Wilhelm Braun (1862-1934).

Charles Frédéric Kuhlmann (22 May 1803 – 27 January 1881) was a French chemist who patented the reaction for converting ammonia to nitric acid, which was later used in the Ostwald process.He was both a research scientist and a professor at Université Lille Nord de France. He promoted chemical engineering education for science graduates in Lille and supported the development of École centrale de Lille (IDN).
As an entrepreneur starting in 1829, he established his own chemical company producing sulfuric acid. This company later merged into Pechiney Ugine Kuhlmann group.

Rocco Jemma (1866–1949) was an Italian pediatrician.

Nestor Louis François Gréhant (2 April 1838 in Laon – 26 March 1910) was a French physiologist.
In 1864 he received his medical doctorate in Paris, where he later earned a doctorate in natural sciences (1870). He served as a préparateur to Claude Bernard at the faculty of sciences in Paris, and subsequently became director of the laboratory of general physiology at the École pratique des Hautes Études. In Paris, he also served as a professor of physiology at the Muséum d’Histoire Naturelle. In 1905 he became a member of the Académie de médecine.He is best remembered for his studies of blood and blood circulation (measurement of cardiac output in animals) and respiration. He also made contributions in his research of the nervous system, of muscle activity, toxicology, anaesthesia and experimental hygiene. He developed a number of devices that he used in research, including a grisoumètre (firedamp detector) that was still in use in coal mines up until 1950.

Paul Gibier (October 9, 1851–June 23, 1900) was a French medical doctor and bacteriologist, a researcher into contagious diseases, who founded the New York Pasteur Institute. This was a pioneering private research laboratory concerned with developing bio-medical cures including vaccines and anti-toxins. He was also known for his interest in psychic phenomena.

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.
