Kazimierz Kuratowski (b. February 2, 1896, d. June 18, 1980) was a Polish mathematician who worked primarily in general topology and mathematical logic.
He is probably best known for a celebrated theorem in graph theory: that a graph is planar iff neither the complete graph on vertices nor the complete bipartite graph on a pair of -element sets appear as edge subdivisions of subgraphs of (closely related to Wagner’s theorem that this is the case iff neither nor appear as graph minors of ).
