You walk past a glass display case at University College London and see a man sitting in a chair. He is wearing his old clothes. He has a hat on his head. He is dead.

This is Jeremy Bentham.

He died in 1832. His will was weird. He wanted to be preserved. He wrote a detailed document about how to do it. He didn’t want a grave in the ground. He wanted to still teach. Even from the grave.

The result is his “auto-icon.” It is a skeleton. Attached to the skeleton is a wax replica of his head. The head looks like him. The body is real bone. The face is wax. It is an odd mix of reality and representation.

UCL keeps him in a case. The display started in 1850. That is nearly two centuries ago. The skeleton sits upright. It looks like it is listening to a lecture. It is a physical reminder of a philosopher who thought everything should be calculated.

But there is a catch. The head is not always there.

Bentham’s actual mummified head is stored separately. It is at the Institute of Archaeology at UCL. You cannot see it in the main display case.

The anatomy of an auto-icon

Why does it look this way? The process was strict.

Bentham’s skeleton is the real thing. It is his bones. They were cleaned and preserved. The wax head was made later. It matches his facial features. It is dressed in his best clothes. A coat. A hat. He is seated.

The intent was humor. And instruction. Bentham was a philosopher of utility. He believed in maximizing happiness. Or so the argument goes. Some think this was his final joke. A dark one.

He wanted his presence to remain. To scare students. To make them think. To be a permanent fixture in the university he helped build.

Where is the head now?

The wax head in the case is a copy. A substitute.

The real head, which was mummified, is kept at the Institute of Archaeology. It is not on public view in the same way. It is stored.

This split exists for conservation reasons. Wax degrades. Wax cracks. Wax fades. The wax head in the chair is protected. The real head is in a climate-controlled storage facility. It is safer there.

Visitors see the wax head. They see the bones. They see the hat. They do not see the mummified tissue. That is hidden away.

The philosophy behind the display

Bentham wrote his will in 1831. He died in 1832. The plan took years to execute.

Friends and colleagues carried it out. They were eccentric enough to follow through. They believed in his ideas. Or they found the situation amusing.

The auto-icon is a statement. It is about the body. And what happens after death. Bentham rejected burial. He rejected the cost of a grave. He wanted utility.

He wanted to keep teaching. Even as a skeleton.

The display at UCL is famous. It draws tourists. It draws skeptics. It draws people who wonder why a university keeps a dead philosopher in a chair
