Senator Estes Kefauver

 What's My Line? - Senator Estes Kefauver (Mar 18, 1951)

What's My Line? is a panel game show that originally ran in the United States on the CBS Television Network from 1950 to 1967, originally in black and white and later in color, with subsequent U.S. revivals. The game uses celebrity panelists to question contestants in order to determine their occupation, i.e. their "line of work". The majority of the contestants were from the general public. However, there was one weekly celebrity "mystery guest" for which the panelists were blindfolded. It is on the list of longest-running U.S. primetime network television game-shows. Originally moderated by John Charles Daly and most frequently with regular panelists Dorothy Kilgallen, Arlene Francis, and Bennett Cerf, What's My Line? won three Emmy Awards for "Best Quiz or Audience Participation Show" in 1952, 1953, and 1958 and the Golden Globe Awards for Best TV Show in 1962.[1][2]

Some nostalgia writers have used the adjective live to describe the series as it existed for 17 years, but in fact during the last eight years many episodes were videotaped weeks or months in advance of their telecasts.[3] The show’s announcer acknowledged this fact during the closing credits of every “prerecorded” episode.
