Roland Gérard Barthes (; French: [ʁɔlɑ̃ baʁt]; 12 November 1915 – 26 March 1980) was a French literary theorist, essayist, philosopher, critic, and semiotician. His work engaged in the analysis of a variety of sign systems, mainly derived from Western popular culture. His ideas explored a diverse range of fields and influenced the development of many schools of theory, including structuralism, anthropology, literary theory, and post-structuralism.
Barthes is perhaps best known for his 1957 essay collection Mythologies, which contained reflections on popular culture, and the 1967/1968 essay "The Death of the Author," which critiqued traditional approaches in literary criticism. During his academic career he was primarily associated with the École des Hautes Études en Sciences Sociales (EHESS) and the Collège de France.

Maurice Lévy (February 28, 1838, in Ribeauvillé – September 30, 1910, in Paris) was a French engineer and member of the Institut de France.
Lévy was born in Ribeauvillé in Alsace. Educated at the École Polytechnique, where he was a student of Adhémar Jean Claude Barré de Saint-Venant, and the École des Ponts et Chaussées, he became an engineer in 1863. During the Franco-Prussian War (1870–1871), he was entrusted by the Government of National Defense with the control of part of the artillery. During the next decade he held several educational positions, becoming professor at the École Centrale in 1875, member of the commission of the geodetic survey of France in 1879, and professor at the Collège de France in 1885.

Henri Marie René Leriche (12 October 1879 – 28 December 1955) was a French vascular surgeon and physiologist.
He was a specialist in pain, vascular surgery and the sympathetic trunk. He sensitized many who were mutilated in the first World war, he was the first to be interested in pain and to practice gentle surgery with as little trauma as possible.
Two symptoms have the name Algoneurodystrophy and the aortic iliac obliteration. He has trained many students, such as Michael E. DeBakey, Jão Cid dos Santos, René Fontaine et Jean Kunlino.

Prof Emil Clement Jungfleisch FRSE MIF (1839-1916) was a French biochemist and pharmacist. He studied molecular dissymmetry.

Jean Hyppolite (French pronunciation: [ʒɑ̃ ipɔlit]; 8 January 1907 – 26 October 1968) was a French philosopher known for championing the work of G.W.F. Hegel, and other German philosophers, and educating some of France's most prominent post-war thinkers. His major works include Genèse et structure de la Phénoménologie de l'esprit de Hegel (1946) and Études sur Marx et Hegel (1955) and the first translation of Hegel's The Phenomenology of Spirit into French in 1939.

Louis-Félix Henneguy (18 March 1850 – 16 January 1928) was a French zoologist and embryologist born in Paris.
In 1875, he received his medical doctorate from the University of Montpellier with a dissertation on the physiological action of poisons, Étude physiologique sur l'action des poisons. In 1883 he obtained his agrégation with Les lichens utiles, a thesis on useful lichens.
During his career he was a professor of comparative embryology at the Collège de France (1900–28), and a member of the Académie de Médecine, the Académie d'Agriculture and the Académie des sciences (1908–28). From 1894 he was director of the journal, Archives d'anatomie microscopique.
He is known for his extensive research of phylloxera, publishing a number of papers on means of destroying its eggs during the winter (1885, 1887–88). Also he performed studies on the natural history of the apple blossom weevil, proposing methods for its eradication (1891). On behalf of the Marine Fisheries Advisory Committee, he did reviews involving the sale and consumption of mussels throughout the year.
With Hungarian neuroanatomist, Mihály Lenhossék (1863–1937), the "Henneguy–Lenhossek theory" is named, which states the claim that mitotic centrioles and ciliary basal kinetosomes are fundamentally the same structure.As a taxonomist he circumscribed the apicomplexan genus Rhytidocystis, and the protozoan genera Thelohania and Fabrea. The genus Henneguya Thélohan, 1892 is named after him, as are the species Apherusa henneguyi Chevreux & Fage, 1925 and Ectinosoma henneguyi Labbé, 1926.In 1903 he was appointed president of the Société entomologique de France.

Marcel Eugène Émile Gley (French: [glɛ]; 18 January 1857 – 24 October 1930) was a French physiologist and endocrinologist born in Épinal, Vosges.
He studied physiology with Henri-Étienne Beaunis at the medical school in Nancy, and afterwards worked as an assistant to Étienne-Jules Marey (1830–1904) in Paris. Later on, he received the title of professeur agrégé, and in 1908 became a professor at the Collège de France. He was a member of the Académie de Médecine and secretary general of the Société de Biologie. He was a colleague to Charles Richet (1850–1935), and with Richet, published the Journal de physiologie et de pathologie générale. With Belgian pharmacologist Jean-François Heymans, he founded the journal Archives Internationales de Pharmacodynamie et de Thérapie (1895).In 1891 Gley was the first to discover the importance of the parathyroid glands, which are four (or more) small endocrine glands lying close or embedded in the posterior surface of the thyroid gland. These glands had been recently discovered as an anatomical entity in 1880, however their importance was not understood at the time. Gley realized that the cause of tetany after thyroid operations was the inadvertent destruction of the parathyroid glands. He demonstrated this by removing the parathyroid glands from laboratory animals and witnessing their deaths from tetany. Because of his discovery, parathyroid glands have sometimes been referred to as "Gley's glands".
In his studies of the thyroid, he discovered that there was much more iodine in thyroid tissue than in the parathyroid, and noticed that when the thyroid is removed, a disturbance of iodine metabolism occurs.

Charles-Émile François-Franck (7 May 1849, Paris – 8 September 1921, Paris) was a French physiologist.
From 1871 he served as a hospital intern in Bordeaux, later returning to Paris, where he worked as an assistant to Étienne-Jules Marey in the laboratory of pathophysiology at the Collège de France. In 1885 he was named director of the laboratory, and in 1890, attained the title of professor. Among his assistants at the Collège de France was neuropathologist Gustave Roussy. In 1887 he was elected as a member of the Académie Nationale de Médecine.His research included studies of vasomotor regulation, pulmonary blood flow and investigations involving the cerebral localization of function. He was a pioneer of sympathectomy (interruption of the sympathetic nervous system for relieving pain) and remembered for his usage of cinematography to accurately record body movements.

Charles Dufraisse (20 August 1885, in Excideuil – 5 August 1969, in Excideuil) was a French chemist. With Charles Moureu, he conducted pioneer research of autoxidation and antioxidants.
In 1921 he received his doctorate at Paris with the thesis Contribution à l'étude de la stéréoisomérie éthylénique, and served as an associate director in the laboratory of organic chemistry at the Collège de France. In 1927 he was named a professor at the École supérieure de physique et de chimie industrielles de la Ville de Paris, and in 1942 became a professor at the Collège de France. He was cofounder of the Institut français du caoutchouc (French Institute of Rubber).

Stéphane Marcel Delépine (19 September 1871, in Saint-Martin-le-Gaillard – 21 September 1965) was a French pharmacist and chemist, whose name is associated with the Delépine reaction for the preparation of primary amines.
He studied at the Sorbonne and at the École Supérieure de Pharmacie in Paris, receiving his doctorate in 1898 with the thesis Amines et amides dérivés des aldéhydes ("The amines and amide derivatives of aldehydes"). From 1895 to 1902 he served as préparateur at the Collège de France, where he worked in the laboratory of Marcellin Berthelot. In 1902 he was named chief pharmacist to the hospitals of Paris, a position he maintained up until 1927.From 1904 he was an agrégé at the École Supérieure de Pharmacie, attaining the chair of hydrology and hygiene in 1913. In 1930 he was appointed a professor of organic chemistry at the Collège de France.In 1927 he became a scientific advisor for Etablissements Poulenc, and subsequently was named director of pharmaceutical research for Rhône-Poulenc. In 1930 he became a member of the Académie des sciences.His work involved research in the fields of organic, inorganic and general chemistry. He made contributions in his investigations of terpenes, platinum group metals (iridium, rhodium), sulfur compounds, et al. In 1935 he described a general method for catalytic hydrogenation with Raney nickel. Also, when experimenting with thiocarbonic esters and related bodies, he discovered the phenomena of "oxyluminescence". In addition, he is credited for introducing a new process for preparation of pure tungsten.
