Ákos Császár (born 26 February 1924, Budapest) is a Hungarian mathematician, specializing in general topology and real analysis. He discovered the Császár polyhedron, a nonconvex polyhedron without diagonals. He introduced the notion of syntopogeneous spaces, a generalization of topological spaces. During the end of 1944 his grandfather lost his life during the siege of Budapest. Then his father, older brother and himself werearrested by the conquerors and sent in a concentration camp approximatively 45 miles East of Budapest. An infectious illnessspread in the camp and his brother and father died but Ákos survived. He is a member of the group of five students ofthe late professor Lipót Fejér who called them "The Big Five". Four members of the group are retired mathematics professorsin North America and only Császár became a university professor in Budapest. Between 1952 and 1992 he was head of the Department of Analysis at the Eötvös Loránd University, Budapest.Corresponding member (1970), member (1979) of the Hungarian Academy of Sciences. He has been general secretary (1966–1980), president (1980–1990), honorary president (since 1990) of the János Bolyai Mathematical Society. He received the Kossuth Prize (1963) and the Gold Medal of the Hungarian Academy of Sciences (2009).
