Eminent mathematician David Hilbert (1862-1943) is not known for his interest or works in economics. In fact, Hilbert never did any work in economics. His primary obsession was mathematics, and sometimes—such as when he raced Einstein to find the field equations of general relativity
David Hilbert did discuss in his lectures the axiomatization of economics. Hilbert's pupil, Herman Weyl, wrote in 1944: "In his lectures he liked to illustrate the method by examples taken from biology, economics, and so on." See: Weintraub (2002) How Economics Became a Mathematical Science, p. 88.
