Random matrix theory (RMT) was introduced into the theoretical physics community by Eugene Wigner in the 1950s as a model for scattering resonances of neutrons off large nuclei. In multivariante statistics, random matrix models were introduced in the late 1920s by John Wishart and subsequently developed by Anderson, James and …
