“ From his earliest years he devoted himself to historical and geographical research, and his first work, Egregiarum seu selectarum lectionum et antiquitatum liber, published in his eighteenth year, displayed great erudition. He enjoyed the patronage of Cardinal Richelieu, a native of the same district with himself, through whose influence he was appointed historiographer and geographer to the king. ”

“ Besides these du Chesne published a great number of genealogical histories of illustrious families, of which the best is that of the house of Montmorency. His Histoire des cardinaux français (2 vols. fol. 1660–1666) and Histoire des chanceliers et gardes des sceaux de France (1630) were published by his son François. André also published a translation of the Satires of Juvenal, and editions of the works of Alcuin, Abelard, Alain Chartier and Étienne Pasquier. ”
