Jack Benny (February 14, 1894 – December 26, 1974), born Benjamin Kubelsky, was an American comedian, vaudeville performer, and radio, television, and film actor. He was one of the biggest stars in classic American radio and was also a major television personality.
Benny may have been the first standup comedian, as the term is known, as well as one of the first to work with what became the situation comedy. He was renowned for his flawless comic timing and (especially) his ability to get laughs with either a pregnant pause or a single expression. In hand with his great "rival" Fred Allen — their long-running "feud" was one of the greatest running gags in comedy history — Benny helped establish a basic palette from which comedy since has rarely deviated, no matter how extreme or experimental it has become in their wake.
