Peter Marshall (Ralph Pierre LaCock 1926) is an actor, singer, TV host, and radio personality on television, movie, and Broadway. He is the brother of actress Joanne Dru (Red River, She Wore a Yellow Ribbon, and All the King's Men).
Born into a show business family, he came by his Broadway credits and singing career naturally. By the 1950s Marshall earned his living in a comedy act with Tommy Noonan, appearing in nightclubs, on television variety shows, and in three forgettable films. The team attempted to capitalize on the popularity of Dean Martin & Jerry Lewis with Noonan as Lewis to Marshall's Martin.
But he is best known to television viewers as the unflappable host of some 5,000 episodes of The Hollywood Squares from 1966 to 1981. When his tenure expired, Marshall continued as a game show host and actor in various television shows. For cable subscribers, Marshall, along with co-host, singer Debby Boone, was featured in a successful infomercial presented by Time Life, the Music of Your Life Collection. Featuring hit songs from the 1950s, 1960s, and 1970s, the infomercial was re-released in 2016. Marshall retired in 2021.
