Jack Paar (1918-2004) was a radio and television personality who hosted an early version of The Tonight Show (Tonight with Jack Paar; 1957-1962) and later The Jack Paar Program (1962-1965). On both series, he played host to early variety show appearances by Jim Henson and the Muppets.
Paar began his career on radio, as an announcer and disc jockey and then with his own The Jack Paar Show in 1947 (initially as a summer replacement for Jack Benny). He also appeared on various TV game shows, including What's My Line? and To Tell the Truth.
