GameShow creator and producer who, as part Creator/MarkGoodson's staff from 1956-65, created ''Series/{{Password}}'' and ''Series/ToTellTheTruth''. He developed ''Series/ThePriceIsRight'' independently (as ''Auction-Aire''), and it was picked up by Goodson-Todman in 1956. In 1965, Stewart left Goodson-Todman and started his own production company with BillCullen as emcee many times.

Stewart died on May 4, 2012 and, while he had nothing to do with the current Creator/{{CBS}} version of ''Price'', the show recognized him as its creator in a post-show memorial on May 7 a marked (and welcome) change from several instances in the 1980s-90s where Bob Barker referred to Goodson as the show's creator.
