On returning home to Fort Bragg after the war, Larry opened the only television sales and service shop in town, on East Redwood Avenue. Much as he had with his plane during his war service, Larry used his own TV repair equipment to independently measure the speed of light, among other home-grown experiments. When he wasn’t experimenting or investigating the laws of nature and physics, Larry was a gifted craftsman, making delightful creations from found materials, some of which can still be seen today at the museum bearing his name.
When Larry retired from the TV business, he converted his shop into the Larry Spring School of Common Sense Physics, where he taught students about his experiments, inventions, and philosophy. Today, Larry’s former shop and school is the Larry Spring Museum, highlighting Larry’s experiments, hand-made creations, collections, and artworks.
