Gustave Flaubert was an influential French novelist who was perhaps the leading exponent of literary realism in his country. He is known especially for his first published novel, Madame Bovary, for his Correspondence, and for his scrupulous devotion to his style and aesthetics. The celebrated short story writer Guy de Maupassant was a protégé of Flaubert.
