Walter Darcy Ryan and His Electric Scintillator

Abstract

In order to publicize the capabilities of General Electric’s lighting department and to solicit more contracts, lead engineer Walter Darcy Ryan came up with a spectacular lighting effect. He called it the “Scintillator.” It was showcased at Wonderland, a local amusement park and to illuminate Niagara Falls, and then appeared at international exhibitions and World’s Fairs in New York, Chicago, San Francisco, and elsewhere for the next quarter of a century. It was also used atop some buildings, and helped inspire the “searchlight” motif in Art Deco depictions of cities. Wanter Darcy Ryan had effectively invented the light show.
