Benny Goodman, born Benjamin David Goodman, (May 30, 1909 – June 13, 1986) was an American jazz musician, known as King of Swing, Patriarch of the Clarinet, The Professor, and Swing's Senior Statesman. Goodman was regarded by some as a demanding taskmaster, by others an arrogant and eccentric martinet. Many musicians spoke of The Ray, Goodman's trademark glare that he bestowed on a musician who failed to perform to his demanding standards. Anita O'Day and Helen Forrest spoke bitterly of their experiences singing with Goodman.
