Nicolas Francois Mansard
Architect, born Paris, France, 1598; died there, 1666.
An exponent of the French Renaissance at its best, he erected several chateaux and hotels distinguished for simplicity and essential beauty of construction.
His best works are Maison Lafitte and the plan for the abbey church of Val-de-Grace which he executed, on a smaller scale, in the chapel of the Chateau de Fresnes.
The curbed roof with large dormer windows was named mansard from his extensive use of it.
