Abstract

Few mathematical concepts can trace their origins to the labor camps of World War II and to the mathematical jottings of an abstract artist. In this article we trace the origins of the crossing number of a graph, the minimum number of crossings that arise when the graph is drawn in the plane, with particular reference to the war-time experiences of the Hungarian number-theorist Paul Turan and to the geometrical explorations of the British artist Anthony Hill.
