Jacques Salomon Hadamard was a French mathematician who made major contributions in number theory, complex analysis, differential geometry and partial differential equations.
Norman Levinson was an American mathematician. Some of his major contributions were in the study of Fourier transforms, complex analysis, non-linear differential equations, number theory, and signal processing. He worked closely with Norbert Wiener in his early career. He joined the faculty of the Massachusetts Institute of Technology in 1937. In 1954, he was awarded the Bôcher Memorial Prize of the American Mathematical Society and in 1971 the Chauvenet Prize of the Mathematical Association of America for his paper A Motivated Account of an Elementary Proof of the Prime Number Theorem. In 1974 he published a paper proving that more than a third of the zeros of the Riemann zeta function lie on the critical line, a result later improved to two fifths by Conrey.
Oskar Perron was a German mathematician.
Édouard Jean-Baptiste Goursat was a French mathematician, now remembered principally as an expositor for his Cours d'analyse mathématique, which appeared in the first decade of the twentieth century. It set a standard for the high-level teaching of mathematical analysis, especially complex analysis. This text was reviewed by William Fogg Osgood for the Bulletin of the American Mathematical Society. This led to its translation into English by Earle Raymond Hedrick published by Ginn and Company. Goursat also published texts on partial differential equations and hypergeometric series.
Edward Charles "Ted" Titchmarsh was a leading British mathematician.
Francis Joseph Murray was a mathematician, known for his foundational work on functional analysis, and what subsequently became known as von Neumann algebras. He received his PhD from Columbia University in 1936. He taught at Duke University.
Hans Lewy was a Jewish American mathematician, known for his work on partial differential equations and on the theory of functions of several complex variables.
Théophile Ernest de Donder was a Belgian mathematician and physicist famous for his work in developing correlations between the Newtonian concept of chemical affinity and the Gibbsian concept of free energy.
Lipman "Lipa" Bers was a Latvian-American mathematician, born in Riga, who created the theory of pseudoanalytic functions and worked on Riemann surfaces and Kleinian groups. He was also known for his work in human rights activism.
Joseph Fels Ritt was an American mathematician at Columbia University in the early 20th century. He was born and died in New York.
Hans F. Weinberger was an Austrian-American mathematician, known for his contributions to variational methods for eigenvalue problems, partial differential equations, and fluid dynamics.
Shmuel Agmon is an Israeli mathematician. He is known for his work in analysis and partial differential equations.
Edward James McShane was an American mathematician noted for his advancements of the calculus of variations, integration theory, stochastic calculus, and exterior ballistics. His name is associated with the McShane–Whitney extension theorem and McShane integral. McShane was professor of mathematics at the University of Virginia, president of the American Mathematical Society, president of the Mathematical Association of America, a member of the National Science Board and a member of the National Academy of Sciences.
Lynn Harold Loomis was an American mathematician working on analysis. Together with Hassler Whitney, he discovered the Loomis–Whitney inequality.
Paul Charles Rosenbloom was an American mathematician.
Rudolf Ernest Langer was an American mathematician, known for the Langer correction and as a president of the Mathematical Association of America.
Nolan Russell Wallach is a mathematician known for work in the representation theory of reductive algebraic groups. He is the author of the 2-volume treatise Real Reductive Groups.
Lloyd Lyne Dines was an American-Canadian mathematician, known for his pioneering work on linear inequalities.
George Roger Sell was an American mathematician, specializing in differential equations, dynamical systems, and applications to fluid dynamics, climate modeling, control systems, and other subjects.
Ernest Preston Lane was an American mathematician, specializing in differential geometry.
