Whatever improvement our penal laws have undergone in the last hundred years is due primarily to Beccaria, and to an extent that has not always been recognised. Lord Mansfield is said never to have mentioned his name without a sign of respect. Romilly referred to him in the very first speech he delivered in the House of Commons on the subject of law reform. And there is no English writer of that day who, in treating of the criminal law, does not refer to Beccaria.
