Benjamin Kubelsky, known professionally as Jack Benny, was an American entertainer, who evolved from a modest success playing violin on the vaudeville circuit to 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 pregnant pause or a single expression, such as his signature exasperated "Well! "
His radio and television programs, popular from 1932 until his death in 1974, were a major influence on the sitcom genre. Benny often portrayed his character as a miser who obliviously played his violin badly and ridiculously claimed to be 39 years of age, regardless of his actual age.
