Gaston Maurice Julia was a French mathematician who devised the formula for the Julia set. His works were popularized by French mathematician Benoit Mandelbrot; the Julia and Mandelbrot fractals are closely related.
Jacques Salomon Hadamard was a French mathematician who made major contributions in number theory, complex analysis, differential geometry and partial differential equations.
Claude Chevalley was a French mathematician who made important contributions to number theory, algebraic geometry, class field theory, finite group theory and the theory of algebraic groups. He was a founding member of the Bourbaki group.
Élie Joseph Cartan, ForMemRS was an influential French mathematician who did fundamental work in the theory of Lie groups, differential systems, and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century.
Oswald Veblen was an American mathematician, geometer and topologist, whose work found application in atomic physics and the theory of relativity. He proved the Jordan curve theorem in 1905; while this was long considered the first rigorous proof of the theorem, many now also consider Camille Jordan's original proof rigorous.
Forest Ray Moulton was an American astronomer.
Jean Alexandre Eugène Dieudonné was a French mathematician, notable for research in abstract algebra, algebraic geometry, and functional analysis, for close involvement with the Nicolas Bourbaki pseudonymous group and the Éléments de géométrie algébrique project of Alexander Grothendieck, and as a historian of mathematics, particularly in the fields of functional analysis and algebraic topology. His work on the classical groups, and on formal groups, introducing what now are called Dieudonné modules, had a major effect on those fields.
Szolem Mandelbrojt was a Polish-French mathematician who specialized in mathematical analysis. He was a Professor at the Collège de France from 1938 to 1972, where he held the Chair of Analytical Mechanics and Celestial Mechanics.
Max Abraham was a German physicist known for his work on electromagnetism and his opposition to the theory of relativity.
Arnaud Denjoy was a French mathematician.
Luther Pfahler Eisenhart was an American mathematician, best known today for his contributions to semi-Riemannian geometry.
Paul Matthieu Hermann Laurent was a French mathematician. Despite his large body of works, Laurent series expansions for complex functions were not named after him, but after Pierre Alphonse Laurent.
Lucien Godeaux (1887–1975) was a prolific Belgian mathematician. His total of more than 1000 papers and books, 669 of which are found in Mathematical Reviews, made him one of the most published mathematicians. He was the sole author of all but one of his papers.
Dominique Foata is a mathematician who works in enumerative combinatorics. With Pierre Cartier and Marcel-Paul Schützenberger he pioneered the modern approach to classical combinatorics, that lead, in part, to the current blossoming of algebraic combinatorics. His pioneering work on permutation statistics, and his combinatorial approach to special functions, are especially notable.
Georg Scheffers was a German mathematician specializing in differential geometry. He was born on 21 November 1866 in the village of Altendorf near Holzminden. Scheffers began his university career at the University of Leipzig where he studied with Felix Klein and Sophus Lie. Scheffers was a coauthor with Lie for three of the earliest expressions of Lie theory:
Georges Louis Bouligand was a French mathematician who introduced paratingent cones and contingent cones.
Jacques Charles Émile Jouguet was a French engineer and scientist, whose name is attached to the Chapman–Jouguet condition.
Léon Lecornu was a French engineer and physicist.
Gustave Juvet was a Swiss mathematician.
Louis-Gustave du Pasquier was a Swiss mathematician and historian of mathematics and mathematical sciences.
