Jack Benny was an American entertainer who evolved from a modest success playing the violin on the vaudeville circuit to one of the leading entertainers of the twentieth century with a highly popular comedic career in radio, television, and film. He was known for his comic timing and the ability to cause laughter with a long pause or a single expression, such as his signature exasperated summation "Well! "
His radio and television programs, popular from 1932 until his death in 1974, were a major influence on the sitcom genre. Benny portrayed himself as a miser who obliviously played his violin badly and claimed perpetually to be 39 years of age.
