Jacques_Stern

Jacques Stern (born 21 August 1949) is a cryptographer, currently a professor at the École Normale Supérieure. He received the 2006 CNRS Gold medal. His notable work includes the cryptanalysis of numerous encryption and signature schemes, the design of the Pointcheval–Stern signature algorithm, the Naccache–Stern cryptosystem and Naccache–Stern knapsack cryptosystem, and the block ciphers CS-Cipher, DFC, and xmx. He also contributed to the cryptanalysis of the SFLASH signature scheme.

Laurent_Nottale

Laurent Nottale (born 29 July 1952) is an astrophysicist, a retired director of research at CNRS, and a researcher at the Paris Observatory. He is the author and inventor of the theory of scale relativity, which aims to unify quantum physics and relativity theory.

Auguste_Bravais

Auguste Bravais (French pronunciation: [oɡyst bʁavɛ]; 23 August 1811, Annonay, Ardèche – 30 March 1863, Le Chesnay, France) was a French physicist known for his work in crystallography, the conception of Bravais lattices, and the formulation of Bravais law. Bravais also studied magnetism, the northern lights, meteorology, geobotany, phyllotaxis, astronomy, statistics and hydrography.
He studied at the Collège Stanislas in Paris before joining the École Polytechnique in 1829, where he was a classmate of groundbreaking mathematician Évariste Galois, whom Bravais actually beat in a scholastic mathematics competition. Towards the end of his studies he became a naval officer, and sailed on the Finistere in 1832 as well as the Loiret afterwards. He took part in hydrographic work along the Algerian Coast. He participated in the Recherche expedition and helped the Lilloise in Spitzbergen and Lapland.
Bravais taught a course in applied mathematics for astronomy in the Faculty of Sciences in Lyon, starting in 1840. He succeeded Victor Le Chevalier in the Chair of Physics at the Ecole Polytechnique from 1845 until 1856 when he was replaced by Henri Hureau de Sénarmont. In 1844 he published a paper on the statistical concept of correlation, and arrived at a definition of the correlation coefficient before Karl Pearson. He is, however, best remembered for his work on Bravais lattices, particularly his 1848 discovery that there are 14 unique lattices in three-dimensional crystalline systems, correcting the previous scheme, with 15 lattices, conceived by Frankenheim three years before.
Bravais published a memoir about crystallography in 1847. A co-founder of the Société météorologique de France, he joined the French Academy of Sciences in 1854. Bravais also worked on the theory of observational errors, a field in which he is especially known for his 1846 paper "Mathematical analysis on the probability of errors of a point".
The mountain Bravaisberget, in Svalbard, is named after Bravais.

Adrien_Douady

Adrien Douady (French: [adʁijɛ̃ dwadi]; 25 September 1935 – 2 November 2006) was a French mathematician born in La Tronche, Isère. He was the son of Daniel Douady and Guilhen Douady.Douady was a student of Henri Cartan at the École normale supérieure, and initially worked in homological algebra. His thesis concerned deformations of complex analytic spaces. Subsequently, he became more interested in the work of Pierre Fatou and Gaston Julia and made significant contributions to the fields of analytic geometry and dynamical systems. Together with his former student John H. Hubbard, he launched a new subject, and a new school, studying properties of iterated quadratic complex mappings. They made important mathematical contributions in this field of complex dynamics, including a study of the Mandelbrot set. One of their most fundamental results is that the Mandelbrot set is connected; perhaps most important is their theory of renormalization of (polynomial-like) maps. The Douady rabbit, a quadratic filled Julia set, is named after him.
Douady taught at the University of Nice and was a professor at the Paris-Sud 11 University, Orsay. He was a member of Bourbaki and an invited speaker at the International Congress of Mathematicians in 1966 at Moscow and again in 1986 in Berkeley.
He was elected to the Académie des Sciences in 1997, and was featured in the French animation project Dimensions.
He died after diving into the cold Mediterranean from a favourite spot near his vacation home in the Var.
His son, Raphael Douady, is also a noted mathematician and an economist.

Raymond_Daudel

Raymond Daudel (2 February 1920 – 20 June 2006) was a French theoretical and quantum chemist.
Trained as a physicist, he was an assistant to Irène Joliot-Curie at the Radium Institute. Daudel spent almost the entirety of his career as professor at the Sorbonne and director of a laboratory of the Centre National de la Recherche Scientifique (CNRS). He is quoted as saying that the latter "was much better because the CNRS was very rich". This allowed Daudel to attract many co-workers from elsewhere in France and internationally.
Raymond Daudel was Officier de la Légion d'honneur and Officier de l'Ordre National du Mérite. He served as President of the European Academy of Arts Sciences and Humanities, in Paris, France. Daudel was a founding member and Honorary President of the International Academy of Quantum Molecular Science.An author as well as an academic, Raymond Daudel authored several books, including Quantum chemistry, originally with R. Lefebyre and C. Moser in 1959 (Interscience Publishers, Inc., New York) and later with G. Leroy, D. Peeters, and M. Sana, published by Wiley in 1983. He was responsible for the organization of the first International Congress in Quantum Chemistry, held in Menton, France in 1973.

Robert_Esnault-Pelterie

Robert Albert Charles Esnault-Pelterie (8 November 1881 – 6 December 1957) was a French aircraft designer and spaceflight theorist. He is referred to as being one of the founders of modern rocketry and astronautics, along with the Russian Konstantin Tsiolkovsky, the Germans Hermann Oberth, Wernher Von Braun and the American Robert H. Goddard.

Michel_Broué

Michel Broué (born 28 October 1946) is a French mathematician. He holds a chair at Paris Diderot University. Broué has made contributions to algebraic geometry and representation theory.
In 2012 he became a fellow of the American Mathematical Society.He is the son of French historian Pierre Broué and the father of French director and screenwriter Isabelle Broué and of French journalist and radio producer Caroline Broué.

Édouard_Brézin

Édouard Brézin (French: [bʁezɛ̃]; born 1 December 1938 Paris) is a French theoretical physicist. He is professor at Université Paris 6, working at the laboratory for theoretical physics (LPT) of the École Normale Supérieure since 1986.
