Jack Benny was an American comedian, vaudevillian, radio, television, and film actor, and violinist. Recognized as a leading American entertainer of the 20th century, Benny portrayed his character as a miser, playing his violin badly. In character, he would be 39 years of age, regardless of his actual age. Benny was known for comic timing, and the ability to create laughter with a pregnant pause or a single expression, such as his signature exasperated "Well!" His radio and television programs, popular from the 1930s to the 1960s, were a major influence on the sitcom genre.
