Jeremy Bentham was an interesting guy who advocated for things like equal rights for women and the abolition of slavery.
Jeremy Bentham also had written into his Will that his body be preserved, stored in a cabinet and brought out for special board meetings.

Then one day his head, which was not preserved well…fell off. So they made a wax one and stuck his real head between his feet ( see picture above) .

I’m sorry to say I couldn’t have made this stuff up.
God, I wish I had.
