John Keown is a leading and widely-published authority on the law and ethics of medicine. Before being appointed to the Rose Kennedy Chair in the Kennedy Institute of Ethics at Georgetown, he taught medical law in the Faculty of Law at Cambridge. In 2015 he was made a Doctor of Civil Law by Oxford for his contribution to law and bioethics. A focus of his research, which has been cited by the Law Lords and by the US Supreme Court, has been the law and practice of euthanasia in the Netherlands. That research formed the centrepiece to the first edition of this work, which was widely acclaimed.
