"Webb2 History of Random Matrix Theory Random matrix theories have fascinated both mathematicians and physicists since they were ﬁrst introduced in mathematical statistics by Wishart in 1928 [2]. After a slow start, the subject gained prominence when Wigner [3] intro-duced the concept of statistical distribution of nuclear energy levels in 1950.
