Michel Georges Francois Peissel (February 11, 1937 – October 7, 2011) was a French ethnologist, explorer and author. He wrote twenty books mostly on his Himalayan and Tibetan expeditions. Peissel was an emeritus member of the Explorers Club and a Fellow of the Royal Geographical Society.

Catherine_Bréchignac

Catherine Bréchignac (French pronunciation: [katʁin bʁeʃiɲak] ; born 12 June 1946) is a French physicist. She is a commander of the Légion d'honneur, "secrétaire perpétuel honoraire" of the Académie des sciences and former president of the CNRS ("National Centre for Scientific Research"). The Times says she has "a formidable reputation for determination, decisiveness and an aptitude for analysing and clarifying complex matters." As a president of the CNRS, she was responsible for 25,000 employees, 12,000 of whom are researchers, and a budget of 2.42 billion Euros.

Henri_Berestycki

Henri Berestycki (born 25 March 1951) is a French mathematician who obtained his PhD from Université Paris VI – Pierre and Marie Curie University in 1975. His Dissertation was titled Contributions à l'étude des problèmes elliptiques non linéaires, and his doctoral advisor was Haïm Brezis. He was an L.E. Dickson Instructor in Mathematics at the University of Chicago from 1975–77, after which he returned to France to continue his research. He has made many contributions in nonlinear analysis, ranging from nonlinear elliptic equations, hamiltonian systems, spectral theory of elliptic operators, and with applications to the description of mathematical modelling of fluid mechanics and combustion. His current research interests include the mathematical modelling of financial markets, mathematical models in biology and especially in ecology, and modelling in social sciences (in particular, urban planning and criminology). For these latter topics, he obtained an ERC Advanced grant in 2012.
He worked at the French National Center of Scientific Research (CNRS), then moved to an appointment as Professor at University Paris XIII (1983–1985). He became a Professor of Mathematics in 1988 at Université Pierre et Marie Curie, Paris VI (1988–2001 of “exceptional class” since 1993), and became professor at École normale supérieure, Paris (1994–1999), and part-time professor at the École Polytechnique (1987–1999). He is also a visiting Professor in the Department of Mathematics at the University of Chicago, and was also co-director of the Stevanovich Center of Financial Mathematics in Chicago. He is currently the Directeur d'études (Research Professor) at École des hautes études en sciences sociales (EHESS), since 2001.

Henry_Louis_Le_Chatelier

Henry Louis Le Chatelier (French pronunciation: [ɑ̃ʁi lwi lə ʃɑtəlje]; 8 October 1850 – 17 September 1936) was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists and chemical engineers to predict the effect a changing condition has on a system in chemical equilibrium.

Pierre_Janssen

Pierre Jules César Janssen (22 February 1824 – 23 December 1907), usually known as Jules Janssen, was a French astronomer who, along with English scientist Joseph Norman Lockyer, is credited with discovering the gaseous nature of the solar chromosphere, and with some justification the element helium.
