Kazimierz Zarankiewicz (1902-1959) was a Polish mathematician and professor at the Warsaw University of Technology whose main interests were topology and graph theory. Born in Czestochowa, he studied at the University of Warsaw among a remarkable circle of Polish topologists and earned his doctorate there in 1923 under Waclaw Sierpinski, with a thesis on points of division in connected sets. He taught in Warsaw, visited Vienna and Berlin in 1930 and 1931, and took part in clandestine teaching during the German occupation, for which he was sent to a concentration camp, though he survived. His name is attached to two problems in graph theory: the Zarankiewicz problem on forbidden complete bipartite subgraphs and the Zarankiewicz crossing number conjecture on complete bipartite graphs. He died in London in 1959.
