Jeremy Bentham was an English philosopher and legal reformer who is regarded as the founder of modern utilitarianism. He attended Oxford University and studied law, but never practiced, instead devoting his life to writing on legal reform. He developed the philosophy of utilitarianism, which asserts that the greatest happiness for the greatest number is the basis of morality. Bentham also coined the concept of the panopticon, a circular prison that allows observers to monitor all prisoners without them knowing if they are being watched. He left over 5 million words of manuscripts at his death and his preserved body is on display at University College London.
