  • Alexis Clairaut1713–1765

    Leading French Newtonian who derived the figure of the Earth from hydrostatics, resolved the motion of the lunar apogee and predicted the 1759 return of Halley's comet.

    geodesy, celestial mechanics, differential geometry

  • Gaspard Monge1746–1818

    Creator of descriptive geometry and founder of the differential geometry of surfaces, who posed the optimal transport problem and helped found the École Polytechnique.

    descriptive geometry, differential geometry, partial differential equations

  • Sophie Germain1776–1831

    Self-taught French mathematician who proved the main nineteenth-century result on Fermat's Last Theorem before Kummer and won the Paris Academy prize for a theory of vibrating elastic plates.

    number theory, elasticity, differential geometry

  • Carl Friedrich Gauss1777–1855

    Founder of modern number theory and the intrinsic geometry of surfaces, and author of least squares, the normal law and Gauss's law.

    number theory, algebra, differential geometry

  • Joseph Liouville1809–1882

    French analyst who founded the Journal de Mathématiques Pures et Appliquées, published Galois's work, constructed the first transcendental numbers and gave his name to theorems on eigenvalue problems, phase-space volume, elementary integrals and conformal maps.

    analysis, differential equations, mathematical physics

  • Bernhard Riemann1826–1866

    Founder of Riemann surfaces and Riemannian geometry, and author of the 1859 paper linking the primes to the zeros of the zeta function.

    complex analysis, differential geometry, analytic number theory

  • Eugenio Beltrami1835–1900

    Italian geometer who gave the first models of Lobachevsky's hyperbolic geometry, proving it as consistent as Euclid's, and whose name survives on the Laplace–Beltrami operator.

    differential geometry, non-euclidean geometry, mathematical physics

  • Gaston Darboux1842–1917

    French geometer whose work on surfaces, orthogonal systems, integration and Pfaffian forms shaped classical differential geometry, and who led the Paris Faculty of Science and the Academy of Sciences.

    differential geometry, real analysis, differential equations

  • Gregorio Ricci-Curbastro1853–1925

    Italian mathematician who created the absolute differential calculus (tensor calculus), introduced covariant differentiation and the Ricci tensor, and with Levi-Civita wrote the 1900 memoir that became the mathematical language of general relativity.

    differential geometry, tensor calculus, mathematical physics

  • Jacques Hadamard1865–1963

    French analyst who proved the prime number theorem, created the theory of entire functions of finite order, and introduced well-posed problems, Hadamard matrices and the study of chaotic geodesic flows.

    complex analysis, analytic number theory, differential geometry

  • Élie Cartan1869–1951

    Completed the classification of simple Lie algebras, discovered spinors, and created exterior differential forms, moving frames, connections with torsion and symmetric spaces.

    lie groups and lie algebras, differential geometry, exterior differential systems

  • Tullio Levi-Civita1873–1941

    Italian mathematician who co-founded tensor calculus with Ricci-Curbastro, introduced parallel transport in Riemannian geometry, regularized binary collisions in the three-body problem, and was dismissed under the 1938 racial laws.

    differential geometry, tensor calculus, rational mechanics

  • Hermann Weyl1885–1955

    Universal mathematician who founded gauge theory and the representation theory of compact Lie groups, and proved the Weyl law and the equidistribution theorem.

    analysis, lie groups and representation theory, differential geometry

  • Heinz Hopf1894–1971

    Topologist who discovered the Hopf fibration and Hopf invariant, proved the Poincaré–Hopf and Hopf degree theorems, and founded the theory of Hopf algebras and group homology.

    algebraic topology, differential geometry, homological algebra

  • André Weil1906–1998

    Founder of Bourbaki who proved the Riemann hypothesis for curves over finite fields and formulated the Weil conjectures.
