Jack Paar
Jack Harold Paar (May 1, 1918 – January 27, 2004) was an American talk show host, writer, radio and television comedian, and film actor. He was the second host of The Tonight Show from 1957 to 1962. Time magazine's obituary of Paar reported wryly, "His fans would remember him as the fellow who split talk show history into two eras: Before Paar and Below Paar."
