He studied medicine at Paris and Padua, and became physician to Louis XIII. In 1629 he became librarian to Cardinal Bagni at Rome, and on Bagni's death in 1641 librarian to Cardinal Barberini.
At the desire of Richelieu he began a wearisome controversy with the Benedictines, denying Gerson's authorship of De Imitatione Christi. Richelieu intended to make Naudé his librarian, and on his death Naudé accepted a similar offer on the part of Mazarin, and for the next ten years devoted himsel to bringing together from all parts of Europe the noble assemblage of books known as the Bibliothéque Mazarine.
Mazarin's library was sold by the parlement of Paris during the trouble of the Fronde, and Queen Christina invited Naudé to Stockholm. He was not happy in Sweden, and on Mazarin's appeal that he should re-form his scattered library Naudé returned at once. But his health was broken, and he died on the journey at Abbeville on the 10th of July I653.
The friend of Gui Patin, of Pierre Gassendi and all the liberal thinkers of his time, Naudé was no mere bookworm; his books show traces of the critical spirit which made him a worthy colleague of the humorists and scholars who prepared the way for the better known writers of the "siècle de Louis XIV"
