Henri Villat

Henri René Pierre Villat ( born December 24, 1879 in Paris, † March 19, 1972 ) was a French Applied mathematician who dealt with theoretical fluid dynamics.

He came from a modest background and lost six years old his father. He went to school in Caen. In 1899 he began to study at the Ecole Normale Superieure, where he specialized in theoretical mechanics. He taught after graduating from a high school in Caen, then became Maître of conférences in Montpellier. He received his Ph.D. in 1911 in Montpellier ( Sur la résistance of the fluid ) in Émile Picard ( Louis and Brillouin ) and dealt not only with applied mathematics, but also with Greek philology ( the Anthologia Palatina ) and visited in a congress in Athens. In 1919 he moved to the now French University of Strasbourg and in 1927, he became professor of hydrodynamics at the Sorbonne. There he was director of the Institute of Mechanics and developed a close collaboration with the sponsored by the French Ministry of Aviation aerodynamic research ( Albert Caquot 1929 coordinated ).

He also taught at the Ecole d' Aéronautique and at the Ecoles Normal Supérieures de Sèvres, a University for Women, where he taught not only mathematics but also philosophy.

In 1932 he became a member of the Academie des Sciences, which he was president in 1948.

In 1920 he organized the International Congress of Mathematicians in Strasbourg and he was until his death the editor of the Journal de Mathématiques et pure appliquées that he saved from decline. He was also the Memorial of Sciences Physique out ( Gauthier -Villars, 1928 ). In 1946, he led the 6th International Congress of Applied Mechanics in Paris.

His doctoral include Jean Leray, Henri Cabannes and the Romanian Caius Iacob.
