Harry E. Williams (1906–1983) was a pioneering American pinball designer, engineer, and entrepreneur who earned the nickname “the Father of Pinball.” In the 1930s, he electrified the game with his groundbreaking creation Contact—one of the first machines to incorporate battery-powered solenoids—and introduced the tilt mechanism to combat cheating. His restless inventive streak shaped pinball’s evolution from simple mechanical novelty to a skillful, action-packed arcade mainstay.
Over a career spanning five decades, Williams founded or co-founded several pivotal companies—including Williams Manufacturing in 1944—and designed more than 150 machines, ranging from classics like Advance and World Series to later-era electronic pinballs like Dracula. His emphasis on fair play, free-game rewards, and dynamic gameplay pushed the industry forward and helped legitimize pinball as a legitimate form of family-friendly amusement. Even today, his influence can be felt on virtually every pinball machine that lights up, buzzes, and challenges players with the timeless tilt warning.
