The limit of the empirical spectral measure for Wigner matrices was described by Eugene Wigner ; see Wigner semicircle distribution. 16. The theory was fully developed by Joe Moyal, each building off earlier ideas by Hermann Weyl and Eugene Wigner . 17. Eugene Wigner ( 1960 ) noted that this culture need not be restricted to mathematics, physics, or even humans.18.
