WJános Dezső Aczél, also known as John Aczel, was a Hungarian-Canadian mathematician, who specialized in functional equations and information theory.
WImre Bárány is a Hungarian mathematician, working in combinatorics and discrete geometry. He works at the Rényi Mathematical Institute of the Hungarian Academy of Sciences, and has a part-time job at University College London.
WJózsef Beck is a Harold H. Martin Professor of Mathematics at Rutgers University.
WPaul Erdős was a renowned Hungarian mathematician. He was one of the most prolific mathematicians and producers of mathematical conjectures of the 20th century. He was known both for his social practice of mathematics and for his eccentric lifestyle. He devoted his waking hours to mathematics, even into his later years—indeed, his death came only hours after he solved a geometry problem at a conference in Warsaw.
WIstván Fenyő was a Hungarian mathematician, whose first name was also known as "Étienne, Stefan, Stephan or Stephen". He was best known for his publications of applied mathematics. He made significant contributions to analysis, algebra, geometry, integral equations and many other fields that pertain to his interests.
WMarcel Grossmann was a mathematician and a friend and classmate of Albert Einstein. Grossmann was a member of an old Swiss family from Zurich. His father managed a textile factory. He became a Professor of Mathematics at the Federal Polytechnic School in Zurich, today the ETH Zurich, specializing in descriptive geometry.
WBéla Kerékjártó was a Hungarian mathematician who wrote numerous articles on topology.
WKlára (Klari) Dán von Neumann was a Hungarian-American computer scientist, noted as one of the first computer programmers.
WRózsa Péter, born Rózsa Politzer, was a Hungarian mathematician and logician. She is best known as the "founding mother of recursion theory".
WGeorge Pólya was a Hungarian mathematician. He was a professor of mathematics from 1914 to 1940 at ETH Zürich and from 1940 to 1953 at Stanford University. He made fundamental contributions to combinatorics, number theory, numerical analysis and probability theory. He is also noted for his work in heuristics and mathematics education. He has been described as one of The Martians.
WFrigyes Riesz was a Hungarian mathematician who made fundamental contributions to functional analysis, as did his younger brother Marcel Riesz.
WAurel Friedrich Wintner was a mathematician noted for his research in mathematical analysis, number theory, differential equations and probability theory. He was one of the founders of probabilistic number theory. He received his Ph.D. from the University of Leipzig in 1928 under the guidance of Leon Lichtenstein. He taught at Johns Hopkins University.
