Jack Benny (born Benjamin Kubelsky) was an American comedian, vaudevillian, radio, television, and film actor, and also a notable violinist. Widely recognized as one of the leading American entertainers of the 20th century, Benny played the role of the comic penny-pinching miser, insisting on remaining 39 years old on stage despite his actual age, and often playing the violin badly. Benny was known for his comic timing and his ability to get laughs with either 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 foundational influence on the situation comedy genre.
