Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Steve Ritchie
Ritchie moved to Chicago, Illinois, the home of Williams' headquarters. His first game for the company, "Flash" (released in 1979), was noted for its revolutionary figure-8 design and the first pinball game to feature bright Flash Lamps. It would go on to be his best-selling pinball game, having sold 19,505 units. 1980 would be the year for Ritchie, when he designed "Firepower" (the first electronic pinball to feature multi-ball, as well as Lane Change), and eight months later, he designed "Black Knight", which was noted for having the first two-level playfield and the patented "Magna-Save" feature (in which magnets help prevent outlane drains).
