CT Scans Reveal Chronic Dental Pain in Jeremy Bentham’s Preserved Head
Advanced imaging confirms the philosopher suffered from severe dental decay and jaw arthritis.
1Philosopher's Final Request
Jeremy Bentham, the influential philosopher who founded University College London, left specific instructions in his 1832 will. He requested that his body be dissected and preserved as an auto-icon, a lasting likeness of himself. Since 1850, his skeleton has been displayed in his own clothes within the university's science collections.
2Modern Diagnostic Imaging
Researchers recently utilized advanced CT scanning technology to examine Bentham’s preserved head without causing any physical damage to the remains. Because the head was wider than the scanner's standard field, the team captured front and back images separately. These were then merged into a single, comprehensive 3D model for analysis.
3Evidence of Chronic Pain
The scans confirmed that Bentham suffered from significant dental damage and an arthritic jaw. These findings align perfectly with his personal correspondence from 1830, where he described enduring agonizing toothaches. He even documented treating his severe nerve pain by applying a heated knitting needle directly to the affected area.
4Preservation Techniques Analyzed
The imaging process provided new insights into how the head was preserved after his death. While the brain was successfully removed, the scan revealed that the dura mater, a tough membrane, remains attached to the skull. Additionally, the glass eyes were found to accurately replicate the structure of the optic nerve.
5Scientific Legacy Continued
Tim Causer of the Bentham Project noted that the philosopher was a strong advocate for experimentation and observation. The team believes Bentham would have approved of this non-invasive study. By digitizing the remains, curators have ensured that this historical object can be studied and protected for future generations of researchers.
6Technological Applications
The 3D data generated from the scans allows for the creation of printed skull replicas. These models serve as valuable tools for healthcare professionals, museum curators, and archaeologists. This digital preservation method allows experts to generate new knowledge about the past without risking the integrity of the original human remains.
7Historical Context of Auto-icons
Thomas Southwood Smith, who originally prepared the auto-icon, struggled to preserve the real head effectively for public viewing. Consequently, a wax replacement was created, and the authentic head was stored in a wooden box in 1948. It is currently kept in a secure safe, protected from environmental degradation and light.
8Future Research Potential
This project highlights the intersection of medical physics and historical preservation. Beyond confirming Bentham's physical suffering, the study opens doors for potential facial reconstruction projects. By combining historical records with modern imaging, scholars can now better understand the daily life and physical reality of figures from the nineteenth century.
