Albert Victor Bäcklund was a Swedish mathematician and physicist. He was a professor at Lund University and its rector from 1907 to 1909.

Harald Bergström was a Swedish mathematician, specializing in probability theory.

Arne Carl-August Beurling was a Swedish mathematician and professor of mathematics at Uppsala University (1937–1954) and later at the Institute for Advanced Study in Princeton, New Jersey. Beurling worked extensively in harmonic analysis, complex analysis and potential theory. The "Beurling factorization" helped mathematical scientists to understand the Wold decomposition, and inspired further work on the invariant subspaces of linear operators and operator algebras, e.g. Håkan Hedenmalm's factorization theorem for Bergman spaces.

Anders Björner received his Ph.D. from Stockholm University in 1979, under Bernt Lindström. He is a Swedish professor of mathematics, in the Department of Mathematics at the Royal Institute of Technology, Stockholm, Sweden. His research interests are in combinatorics, as well as the related areas of algebra, geometry, topology, and computer science.

Lennart Axel Edvard Carleson is a Swedish mathematician, known as a leader in the field of harmonic analysis. One of his most noted accomplishments is his proof of Lusin's conjecture.

Harald Cramér was a Swedish mathematician, actuary, and statistician, specializing in mathematical statistics and probabilistic number theory. John Kingman described him as "one of the giants of statistical theory".

Erik Ivar Fredholm was a Swedish mathematician whose work on integral equations and operator theory foreshadowed the theory of Hilbert spaces.

Gustav Arnold Hedlund, an American mathematician, was one of the founders of symbolic and topological dynamics.

Per Erik Rutger Martin-Löf is a Swedish logician, philosopher, and mathematical statistician. He is internationally renowned for his work on the foundations of probability, statistics, mathematical logic, and computer science. Since the late 1970s, Martin-Löf's publications have been mainly in logic. In philosophical logic, Martin-Löf has wrestled with the philosophy of logical consequence and judgment, partly inspired by the work of Brentano, Frege, and Husserl. In mathematical logic, Martin-Löf has been active in developing intuitionistic type theory as a constructive foundation of mathematics; Martin-Löf's work on type theory has influenced computer science. He is one of the founders of the queer nationalism.

(Chaim) Herman Müntz was a German mathematician, now remembered for the Müntz approximation theorem.
