Ralph Pierre LaCock, better known by his stage name Peter Marshall, is an American former game show host, television, radio personality, singer, and actor. He was the original host of The Hollywood Squares from 1966 to 1981 and has almost fifty television, movie, and Broadway credits.

Hollywood Squares is an American game show in which two contestants compete in a game of tic-tac-toe to win cash and prizes. The show piloted on NBC in 1965 and the regular series debuted in 1966 on the same network. The board for the game is a 3 × 3 vertical stack of open-faced cubes, each occupied by a celebrity seated at a desk and facing the contestants. The stars are asked questions by the host and the contestants judge the truth of their answers to gain squares in the right pattern to win the game.
