Henry Horn's X-Ray Eye Glasses

"Henry Horn's X-Ray Eye Glasses" by Dwight V. Swain is a science fiction short story written during the early 1940s. The narrative follows the misadventures of Henry Horn, a quirky inventor who creates a pair of binoculars that operate on the "x-ray" principle—allowing the user to see through objects. The story unfolds amidst the backdrop of World War II, focusing on espionage and the unintended consequences of Horn's invention. The plot centers around Henry Horn and his colleague, the irate Professor Paulsen, who becomes infuriated when he discovers Horn peddling his x-ray binoculars to curious onlookers at a nudist camp. As the story progresses, the plot thickens when a red-haired man—an actual Nazi spy—purchases the glasses, leading to a race against time to retrieve sensitive military information he might have accessed. Coupled with humorous elements of their nudist encounters and several frantic moments, the story culminates in a showdown that reveals Professor Paulsen's quick wits as they confront the spy, turning an initially comedic invention into a decisive asset in the war effort against the Axis powers.
