American jazz musician, band leader
According to Wikipedia,
Benjamin David Goodman was an American clarinetist and bandleader known as the "King of Swing". From 1936 until the mid-1940s, Goodman led one of the most popular swing big bands in the United States. His concert at Carnegie Hall in New York City on January 16, 1938, is described by critic Bruce Eder as "the single most important jazz or popular music concert in history: jazz's 'coming out' party to the world of 'respectable' music."
