Professor Maurice Cranston, who died suddenly on 5 November 1993, was a man of many talents. Pre-eminent as a biographer of Locke and Rousseau, he was also distinguished for his own contribution to political philosophy and for his capacity to expound the political thought of others in clear, simple language. He did this with great success not only in the lecture room but also in numerous broadcast talks and discussions, notably on the Third Programme (later called Radio 3) of the BBC. In his academic work he was particularly well informed on French political thought, contemporary as much as classical, and he wrote extensively on Sartre and more briefly on Camus and Foucault. He was himself fluent in the French language (though he spoke it with a pronounced English accent) and he translated Rousseau's Social Contract and Discourse on Inequality for the Penguin Classics series. He was proficient in German and Italian too, and he knew enough Danish to translate a book on Wittgenstein written in that language. His love of literature often led him to illustrate philosophical points with apt examples from classical novels. He even wrote a couple of novels (of detection) himself in his youth. It will be plain from this brief catalogue that he was an eminently civilized person. He was, in addition, an exceptionally friendly man and engagingly modest about his own abilities.
