In this Stuff You Should Know episode about historical burial practices, the hosts explore how 19th-century society developed an intense fear of premature burial. This cultural shift coincided with the rise of Romanticism and its focus on spiritual matters, combined with the period's limited medical knowledge about determining death.
The episode details various inventive solutions created to address these fears, including specialized "safety coffins" equipped with bells, breathing tubes, and escape mechanisms. These innovations ranged from Eisenbrandt's spring-loaded coffin lid to Michel de Carnic's bell system, and even included unusual grave designs like Timothy Clark Smith's tomb in Vermont, which featured a window positioned above the deceased's face for visual confirmation of death.

The 19th century saw a widespread fear of premature burial, which emerged alongside the rise of Romanticism. As society moved away from the Enlightenment's rational thinking, Romanticism introduced a renewed focus on spiritual and unseen realms, suggesting a delicate boundary between life and death. This shift in perspective, combined with uncertain medical knowledge of the time, created deep anxieties about the possibility of being buried alive, fears that were notably captured in the works of Edgar Allan Poe.
In response to these fears, inventors developed safety coffins, which offered various mechanisms for survival and escape. These ingenious designs typically featured bells that could be rung from inside the coffin or tubes for breathing and communication. Christian Eisenbrandt's 1843 life-preserving coffin showcased a particularly innovative design with a spring-loaded lid that could be activated by slight movements. Michel de Carnic marketed his "Carnice" device by playing on public fears, using questionable statistics about premature burial rates to promote his design featuring a breathing tube and bell system.
Eisenbrandt's 1843 design for above-ground tombs included an internal key, allowing inhabitants to unlock their tomb if they awakened inside. While innovative, this design assumed the person would be conscious enough to use the key. In a striking example of premature burial anxiety, Timothy Clark Smith's grave in New Haven, Vermont, was constructed with a window above his face, allowing passersby to verify his death and serving as a testament to the period's intense fear of being buried alive.
1-Page Summary
The 19th century brought with it a palpable fear of premature burial, a fear intensified by the rise of Romanticism, which shifted society's imagination away from the Enlightenment's rationalism.
Romanticism was a response to the Enlightenment's staunch rationalism, and it harbored a fascination with the spiritual and the unseen realms. This philosophical and artistic movement suggested that life and what lies beyond were closely linked, weaving the notion that death's threshold was delicate and, perhaps, easily mistread. The rise of Romanticism thus played into burgeoning anxieties about the potential horror of being buried alive. Concepts of an afterlife and the potential for the dead to maintain contact or communication only deepened these dark concerns.

19th Century Fear of Premature Burial
Safety coffins, also known as security coffins, were invented to combat the fear of being buried alive. These ingenious designs provided the prematurely buried with ways to alert the living or even escape the grave.
The main purpose of safety coffins was to allow individuals who were buried alive by mistake to signal to others above ground that they were still alive.
The designs for these coffins typically included a variety of features such as bells or tubes. Some safety coffin designs incorporated a simple mechanism like a bell that could be rung by the buried person by pulling a cord placed in their hand. Others took a more elaborate approach by integrating a tube that connected to the outside air, both for breathing and for communication purposes.
One particularly intricate design was Christian Eisenbrandt's 1843 life-preserving coffin, documented in his patent file. It featured a spring-loaded lid that would activate with the slightest motion of the head or hand, potentially allowing a pe ...
The Various Safety Coffin Designs and Features
The fear of being buried alive has a tangible legacy, with inventions such as safety coffins designed for the purpose of safeguarding against such a fate. Here are specific examples of these macabre innovations.
Christian Eisenbrandt devised a coffin design intended specifically for above-ground vaults. His coffin included an important safety feature: a key that was left on the inside. This ensured that if an individual awoke inside the coffin, they could unlock the tomb and escape from a premature burial.
There was an inherent risk in Eisenbrandt's design. The inclusion of an internal key presumed that the person inside the coffin would have the consciousness and presence of mind to use it if they were, in fact, alive but mistakenly entombed.
Moving on from Eisenbrandt's invention, we encounter Timothy Clark Smith's grave in New Haven, Vermont. This grave had a unique modification: a window was installed ab ...
