Spencer W.C. Cogswell (simply as: Mr. Cogswell) is a character in The Jetsons. He is the CEO of Cosmo Spacely's rival company Cogswell Cogs and the descendent of Mr. Slate from The Flinstones.
Mr. Cogswell is Spacely's big competitor. He owns Cogswell Cogs company and causes a lot of trouble for Spacely and George. To a lesser extent Cogswell is another of the series' antagonists. He and Spacely are always finding ways to bring each other's businesses down. Cogswell has often tried to steal Spacely's ideas and make them his own to gain an advantage (only for it to backfire on both bosses). He's also not above firing his employees when any little thing goes wrong. Mr. Cogswell's first name, "Spencer", is revealed in the 1980s version of The Jetsons. Cogswell slightly resembles Mr. Slate of The Flintstones.
