Otto Szász (11 December 1884 in Hungary to 19 December 1952 in Cincinnati, Ohio) was a Hungarian mathematician who worked on real analysis, in particular on Fourier series. He proved the Müntz-Szász theorem and introduced the Szász-Mirakyan operator. The Hungarian Mathematical and Physical Society awarded him the Julius Kőnig prize in 1939. His collected mathematical papers were published by the department of mathematics of the University of Cincinnati in 1955, and an obituary by Gábor Szegő appeared in the Bulletin of the American Mathematical Society in 1954. His life is also documented in the MacTutor History of Mathematics archive and the Mathematics Genealogy Project.
