Marvin Glass (June 14, 1914 - January 1974) was a game designer and artist. He and his employees created some of the most successful toys and games of the 20th century. His creations include Rock 'Em Sock 'Em Robots, Masterpiece, Mouse Trap, and Operation, but he may be most famous for inventing the mechanical and chattering Yakkity-Yak teeth.
He was inducted in to the Toy Industry Hall of Fame in 1985.
"Glass ... never invented a single toy, but he was the only toy 'inventor' ever to achieve recognition outside the industry. He managed to take credit for everything..." -- Burt Meyer, game designer
