**Jacques-Louis Lions** (French: [ljɔ̃ːs] ;^{ [1] } 3 May 1928 – 17 May 2001) was a French mathematician who made contributions to the theory of partial differential equations and to stochastic control, among other areas. He received the SIAM's John von Neumann Lecture prize in 1986 and numerous other distinctions.^{ [2] }^{ [3] } Lions is listed as an ISI highly cited researcher.^{ [4] }

After being part of the French Résistance in 1943 and 1944, J.-L. Lions entered the École Normale Supérieure in 1947. He was a professor of mathematics at the Université of Nancy, the Faculty of Sciences of Paris, and the École polytechnique.

In 1966 he sent an invitation to Gury Marchuk, the soviet mathematician to visit Paris. This was hand delivered by General De Gaulle during his visit to Akademgorodok in June of that year.^{ [5] }

He joined the prestigious Collège de France as well as the French Academy of Sciences in 1973. In 1979, he was appointed director of the Institut National de la Recherche en Informatique et Automatique (INRIA), where he taught and promoted the use of numerical simulations using finite elements integration. Throughout his career, Lions insisted on the use of mathematics in industry, with a particular involvement in the French space program, as well as in domains such as energy and the environment. This eventually led him to be appointed director of the Centre National d'Etudes Spatiales (CNES) from 1984 to 1992.

Lions was elected President of the International Mathematical Union in 1991 and also received the Japan Prize and the Harvey Prize that same year.^{ [3] } In 1992, the University of Houston awarded him an honorary doctoral degree. He was elected president of the French Academy of Sciences in 1996 and was also a Foreign Member of the Royal Society (ForMemRS)^{ [6] } and numerous other foreign academies.^{ [2] }^{ [3] }

He has left a considerable body of work, among this more than 400 scientific articles, 20 volumes of mathematics that were translated into English and Russian, and major contributions to several collective works, including the 4000 pages of the monumental *Mathematical analysis and numerical methods for science and technology* (in collaboration with Robert Dautray), as well as the *Handbook of numerical analysis* in 7 volumes (with Philippe G. Ciarlet).

His son Pierre-Louis Lions is also a well-known mathematician who was awarded a Fields Medal in 1994.^{ [7] } Both father and son have received honorary doctorates from Heriot-Watt University in 1986 and 1995 respectively.^{ [8] }

**Laurent Lafforgue** is a French mathematician. He has made outstanding contributions to Langlands' program in the fields of number theory and analysis, and in particular proved the Langlands conjectures for the automorphism group of a function field. The crucial contribution by Lafforgue to solve this question is the construction of compactifications of certain moduli stacks of shtukas. The proof was the result of more than six years of concentrated efforts.

He was the President of the International Mathematical Union from 2003–06 and a Fellow of Queen's College, Oxford. He was educated at the University of Cambridge and Sussex University, and prior to taking up his Oxford post was a professor of mathematics at Heriot-Watt University in Edinburgh.

**Wendelin Werner** is a German-born French mathematician working on random processes such as self-avoiding random walks, Brownian motion, Schramm–Loewner evolution, and related theories in probability theory and mathematical physics. In 2006, at the 25th International Congress of Mathematicians in Madrid, Spain he received the Fields Medal "for his contributions to the development of stochastic Loewner evolution, the geometry of two-dimensional Brownian motion, and conformal field theory". He is professor at ETH Zürich.

**Philippe G. Ciarlet** is a French mathematician, known particularly for his work on mathematical analysis of the finite element method. He has contributed also to elasticity, to the theory of plates ans shells and differential geometry.

**Haïm Brezis** is a French mathematician who works in functional analysis and partial differential equations.

**Andrew Joseph Majda** is an American mathematician and the Morse Professor of Arts and Sciences at the Courant Institute of Mathematical Sciences of New York University. He is known for his theoretical contributions to partial differential equations as well as his applied contributions to diverse areas including shock waves, combustion, incompressible flow, vortex dynamics, and atmospheric sciences. Majda is listed as an ISI highly cited researcher in mathematics.

The **Association française pour l'information scientifique** or **AFIS** is an association regulated by the French law of 1901, founded under the leadership of Michel Rouzé in November 1968. As a skeptical organisation, it has been a member of the European Council of Skeptical Organisations since 2001, and publishes the magazine *Science et pseudo-sciences*.
