Delorme, Philibert, born at Lyons about 1518, studied architecture in Rome and became thoroughly imbued with the principles of classical art. His first patron was Cardinal Du Bellay, through whom he obtained the favour of Catherine de Medici and Henry II. He built the crescent at Fontainebleau, the chateaux of Anet and Meudon, and began the palace of the Tuileries. Primaticcio assisted him in many of his designs. His writings as well as his buildings contributed much to the development of the French Renaissance. He died in 1577.
