Isaiah Edwin Leopold (November 9, 1886 – June 19, 1966), better known as Ed Wynn, was an American actor and comedian noted for his Perfect Fool comedy character, his pioneering radio show of the 1930s, and his later career as a dramatic actor.

Ed Wynn first appeared on television on July 7, 1936 in a brief, ad-libbed spot with Graham McNamee during an NBC experimental television broadcast. In the 1949–50 season, Ed Wynn hosted one of the first network, comedy-variety television shows, on CBS, and won both a Peabody Award and an Emmy Award in 1949. Buster Keaton, Lucille Ball, and The Three Stooges all made guest appearances with Wynn. This was the first CBS variety television show to originate from Los Angeles, which was seen live on the west coast, but filmed via kinescope for distribution in the Midwest and East, as the national coaxial cable had yet to be completed. Wynn was also a rotating host of NBC's Four Star Revue from 1950 through 1952.
