Academic staff of the Coll\u00e8ge de France

Louis Marcel Brillouin (French pronunciation: [lwi maʁsɛl bʁijwɛ̃]; 19 December 1854 – 16 June 1948) was a French physicist and mathematician.
Born in Saint-Martin-lès-Melle, Deux-Sèvres, France, his father was a painter who moved to Paris when Marcel was a boy. There he attended the Lycée Condorcet. The Brillouin family returned to Saint-Martin-lès-Melle during the Franco-Prussian War of 1870 to escape the fighting. There he spent time teaching himself from his grandfather's philosophy books. After the war, he returned to Paris and entered the École Normale Supérieure in 1874 and graduated in 1878. He became a physics assistant to Éleuthère Mascart (his future father-in-law) at the Collège de France, while at the same time working for his doctorates in mathematics and physics, which he gained in 1880 and 1882, respectively. Brillouin then held successive posts as assistant professor of physics at universities in Nancy, Dijon and Toulouse before returning to the École Normale Supérieure in Paris in 1888. Later, he was Professor of Mathematical Physics at the Collège de France from 1900 to retirement in 1931.
In 1911 he was one of only six French physicists invited to the first Solvay Conference. He was awarded the Prix La Caze for 1912.
Brillouin was elected to the Académie des Sciences in 1921. He was an officer of the Legion of Honour.During his career he was the author of over 200 experimental and theoretic papers on a wide range of topics which include the kinetic theory of gases, viscosity, thermodynamics, electricity, and the physics of melting conditions. Most notably he:

built a new model of the Eötvös balance,
wrote on Helmholtz flow and the stability of aircraft,
worked on a theory of the tides.Brillouin died in Paris (16 June 1948). His son Léon Brillouin, also had a prominent career in physics.

Joseph Louis François Bertrand (French pronunciation: [ʒozɛf lwi fʁɑ̃swa bɛʁtʁɑ̃]; 11 March 1822 – 5 April 1900) was a French mathematician whose work emphasized number theory, differential geometry, probability theory, economics and thermodynamics.

Pierre Rosanvallon (born 1 January 1948) is a French historian and sociologist. He was named a professor at the Collège de France in 2001, holding the chair in modern and contemporary political history.
His works are dedicated to the history of democracy, French political history, the role of the state and the question of social justice in contemporary societies.

Jacques Thuillier, (March 18, 1928, Vaucouleurs, Meuse – October 18, 2011, Paris) was a French art historian specializing in 17th-century French painting.
Thuillier was an honorary professor at the Collège de France, where he taught history of artistic creation from 1977 to 1998. He was a renowned specialist of French painting and, alongside the late Anthony Blunt, a leading authority on Nicolas Poussin. He published seminal works on the leading French painters of the time, including Simon Vouet, Georges de La Tour, the Le Nain brothers, Laurent de La Hyre, Sébastien Bourdon, Jacques Blanchard and Lubin Baugin. His publications on those painters often took the form of both an exhibition catalogue and a catalogue raisonné based on extensive archival research.
An avid collector, Thuillier donated, while still alive, along with his brother Guy Thuillier, his collection of drawings (2,000) and engravings (13,000) to the Museum of Fine Arts of Nancy and part of his collection of paintings to the art museum at Vic-sur-Seille. He donated to the city of Nevers part of his archives, his library, a collection of drawings and engravings, and his collections of photographs, thus making the Nevers Médiathèque into a documentation centre for French painting of the 17th century. Another part of these archives and manuscripts is held at the INHA (fr), in Paris.

Louis Robert (15 February 1904 in Laurière – 31 May 1985 in Paris) was a professor of Greek history and Epigraphy at the Collège de France, and author of many volumes and articles on Greek epigraphy (from the archaic period to Late Antiquity), numismatics, and historical geography. He was an international authority on the history, geography, toponymy and archaeology of ancient Asia Minor.

Xavier Le Pichon (born 18 June 1937 in Qui Nhơn, French protectorate of Annam (later South Vietnam and today Vietnam)) is a French geophysicist. Among many other contributions, he is known for his comprehensive model of plate tectonics (1968), helping create the field of plate tectonics. In 1968 he combined the kinematic ideas of W. J. Morgan, D. McKenzie and R. L. Parker with the large data sets collected by Lamont, and especially with the respective magnetic profiles, to show that Plate Tectonics could accurately describe the evolution of the major ocean basins. He is professor at the Collège de France, holder of the Chair of Geodynamics (1986–2008). He is a lifelong devout Catholic, and has come to think of caring attention to others' weakness as an essential quality that allowed humanity to evolve. He lives with his wife and has five children and eleven grandchildren.

Claude Hagège (French: [aʒɛʒ]; born 1 January 1936) is a French linguist.

Pierre Hadot (; French: [ado]; 21 February 1922 – 24 April 2010) was a French philosopher and historian of philosophy specializing in ancient philosophy, particularly Epicureanism and Stoicism.

Pascal Georges Dusapin (born 29 May 1955) is a French composer. His music is marked by its microtonality, tension, and energy.
A pupil of Iannis Xenakis and Franco Donatoni and an admirer of Varèse, Dusapin studied at the University of Paris I and Paris VIII during the 1970s. His music is full of "romantic constraint". Despite being a pianist, he refused to compose for the piano until 1997. His melodies have a vocal quality, even in purely instrumental works.
Dusapin has composed solo, chamber, orchestral, vocal, and choral works, as well as several operas, and has been honored with numerous prizes and awards.

Jean Léon Marie Delumeau (18 June 1923 – 13 January 2020) was a French historian specializing in the history of the Catholic Church, and author of several books regarding the subject. He held the Chair of the History of Religious Mentalities (1975–1994) at the Collège de France (former emeritus professor) and was a member of the Académie des inscriptions et belles-lettres.
