Died May 4, 2012. Born August 27, 1920.

American television game show producer. He was active in the TV industry from 1956 until his retirement in 1992.

Stewart is known for creating some of the most popular game shows for Mark Goodson-Bill Todman Productions. These shows include To Tell the Truth, Password, and The Price Is Right. His biggest success as an independent producer was the Pyramid series, starting with The $10,000 Pyramid in 1973.

The Price Is Right and To Tell the Truth, both created by Stewart, are the only two game shows to be seen nationally in either first-run network or syndication airings in the US in every decade from the 1950s onward, although the version of The Price Is Right that has been seen since 1972 on CBS features a retooled format in which Stewart was not involved.

On May 4, 2012, Stewart died at age 91 in a medical center in Los Angeles from natural causes, just sixteen days after Dick Clark, who hosted Pyramid for fifteen years.
