By his mid-thirties his literary activities precipitated a four-year exile in England where he won the praise of Swift and Pope for his political tracts. His publication, three years later in France, of Lettres philosophiques sur les Anglais (1733)—an attack on French Church and State—forced him to flee again. For twenty years Voltaire lived chiefly away from Paris. In this, his most prolific period, he wrote such satirical tales as “Zadig” (1747) and “Candide” (1759). His old age at Ferney, outside Geneva, was made bright by his adopted daughter, “Belle et Bonne,” and marked by his intercessions in behalf of victims of political injustice. Sharp-witted and lean in his white wig, impatient with all appropriate rituals, he died in Paris in 1778—the foremost French author of his day.
