The Coffin Torpedo
In the late 19th century, concerns over grave robbing and body snatching led to the invention of the "coffin torpedo," a device designed to deter would-be grave robbers through explosive means. Patented in 1878 by Philip K. Clover, an artist from Columbus, Ohio, the coffin torpedo functioned like a small shotgun secured inside the coffin lid. If someone attempted to open the coffin, the device would discharge a lethal blast of lead balls, aiming to prevent the unauthorized resurrection of dead bodies.
Another inventor, Thomas N. Howell, patented a similar device in 1881. Howell's coffin torpedo was buried above the coffin and wired to it, operating like a landmine that would detonate when disturbed. An advertisement for Howell's invention read:
"Sleep well sweet angel, let no fears of ghouls disturb thy rest, for above thy shrouded form lies a torpedo, ready to make minced meat of anyone who attempts to convey you to the pickling vat."
Despite the fear of grave robbing, these devices were not widely manufactured or commercially successful. In most cases, having someone watch over the grave for a few days or weeks was sufficient to ensure the body had decomposed enough to be of no use to body snatchers.
