Jeremy Bentham (1748-1832) was a philosopher and social reformer.  His work included arguments in favour of the abolition of slavery, women's and animal rights, the end of corporal punishment, free trade and the separation of church and state.  His work influenced many philosophers, politicians and social campaigners, including Robert Owen, the father of socialism.
