Jack Benny (born Benjamin Kubelsky; February 14, 1894 – December 26, 1974) was an American entertainer who evolved from a modest success as a violinist 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! "

Benny had been a minor vaudeville performer before becoming a national figure with The Jack Benny Program, a weekly radio show that ran from 1932 to 1948 on NBC and from 1949 to 1955 on CBS. It was among the most highly rated programs during its run.
