In a future where privacy is heavily regulated, a mild-mannered historian, Arnold Potterley, seeks permission to use a chronoscope—a device that allows viewing past events—for his research on ancient Carthage. After two years of frustration, he becomes increasingly desperate and considers unethical means to achieve his goal. He encounters Jonas Foster, a young physics instructor, who becomes intrigued by Potterley's passion but is initially resistant to his ideas. Potterley believes that understanding Carthage will correct historical misconceptions, particularly regarding accusations of child sacrifice. He becomes obsessed with the idea of using the chronoscope to reveal the truth. Meanwhile, Foster grapples with the ethical implications of their discussions and the potential consequences of using such a device. As Potterley’s obsession grows, he reveals his plan to build a chronoscope illegally, hoping to bypass government restrictions. Foster, initially skeptical, becomes drawn into Potterley’s vision and begins to see the potential for scientific discovery. However, he also recognizes the dangers of such a device, particularly the invasion of privacy it could enable. The narrative escalates as Foster and Potterley work together, with Foster secretly constructing a rudimentary chronoscope in Potterley’s basement. Their discussions reveal deep philosophical questions about the nature of the past, memory, and the ethical responsibilities of scientists. Potterley’s wife, Caroline, becomes a pivotal figure, representing the emotional stakes involved in their quest. She longs to see their deceased daughter, Laurel, through the chronoscope, highlighting the personal motivations that drive their actions. As the story unfolds, the consequences of their actions become apparent. The government, represented by Thaddeus Araman, seeks to suppress any unauthorized research into chronoscopy, fearing the societal chaos that could ensue if everyone could access their pasts. Araman confronts Foster and Potterley, emphasizing the need for control over such powerful technology to prevent societal collapse. The climax occurs when Foster’s uncle, Ralph Nimmo, inadvertently complicates matters by leaking information about the chronoscope to the media. This act threatens to expose the existence of home-built chronoscopes, leading to widespread panic and potential misuse of the technology. The characters are forced to confront the implications of their actions, as the line between scientific inquiry and ethical responsibility blurs. In the end, the narrative raises profound questions about the nature of curiosity, the ethics of scientific exploration, and the consequences of tampering with the past. The characters grapple with their desires and the potential fallout of their choices, ultimately leading to a world forever changed by the revelations of the chronoscope. The story concludes with a sense of foreboding, as the characters realize that their pursuit of knowledge has unleashed forces they cannot control, leaving humanity to navigate a new reality where the past is no longer a distant memory but an ever-present possibility.

Readers of this story who are up on today's muckraking literature will be familiar with the name of Vance Packard. True, the dangers of electronic spying that Mr. Packard so ominously described In his best-seller The Naked Society do not even approach the terrifying possibilities that are unveiled in the tale you are about to read; but Packard's reports of the misuse of lie detectors, bugged rooms, secret television cameras, and other techniques of listening-and-looking-in on the behavior of Twentieth Century Man are only too suggestive of the final horror Professor Potterly here bestows on the Twenty-First Century world with his innocent-seeming portable chronoscope.
The Dead Past is listed on Textopian as a novel by Isaac Asimov, dated 1956 CE.
